Managing package installations connected macOS tin beryllium a difficult concern. Fortunately, Homebrew simplifies the procedure, however what occurs once you demand a circumstantial interpretation of a expression? Whether or not you’re troubleshooting compatibility points, replicating a ancient situation, oregon merely necessitate an older interpretation, realizing however to instal circumstantial variations with Homebrew is a important accomplishment for immoderate developer oregon scheme head. This usher volition locomotion you done the procedure, offering broad directions, adept insights, and champion practices for managing your Homebrew installations efficaciously.
Pinning to a Circumstantial Interpretation
1 simple manner to instal a circumstantial interpretation is by “pinning” the expression. Pinning prevents Homebrew from routinely upgrading a expression throughout regular operations. This is peculiarly utile once a newer interpretation introduces breaking adjustments. Archetypal, place the desired interpretation utilizing brew hunt
Erstwhile put in, usage brew pin
Utilizing brew variations (Deprecated)
Piece antecedently a communal technique, brew variations is present deprecated. It’s crucial to beryllium alert of this arsenic older tutorials whitethorn inactive mention it. This bid allowed customers to browse and instal older variations straight. Nevertheless, owed to maintainability points, it has been eliminated from Homebrew’s center performance.
The most well-liked technique is present utilizing a pat for older variations oregon putting in from origin if essential.
Putting in from Origin
For eventual power, compiling from origin is an action, although it requires much method experience. Obtain the desired interpretation’s origin codification from the task’s authoritative web site oregon repository. Past, travel the task’s compilation directions, which sometimes affect configuring, gathering, and putting in the package manually. This technique is mostly much analyzable however presents granular power and is utile for border circumstances wherever pre-constructed variations are unavailable.
Retrieve that compiling from origin mightiness present dependencies that aren’t managed by Homebrew, requiring other attraction to scheme configuration.
Leveraging Faucets for Older Variations
Homebrew faucets are 3rd-organization repositories that widen the disposable formulation. Any faucets specialize successful offering older variations of package. For illustration, the homebrew/center pat comprises galore fashionable formulation, and any maintainers supply archived variations successful abstracted faucets. Hunt on-line oregon connected the Homebrew web site to discovery due faucets for your circumstantial wants.
To usage a pat, adhd it utilizing brew pat <tap_name>. Past, instal the circumstantial interpretation utilizing brew instal <tap_name>/
Cardinal Issues for Interpretation Direction
- Compatibility: Guarantee chosen variations activity with another put in package.
- Safety: Older variations whitethorn person identified vulnerabilities. See the safety implications earlier putting in outdated package.
Steps to Instal a Circumstantial Expression Interpretation
- Place the desired interpretation.
- Effort brew instal
@ . - If unavailable, research faucets oregon compiling from origin.
- Pin the interpretation if essential to forestall undesirable upgrades.
Selecting the correct interpretation is important for task stableness. Larn much astir interpretation direction champion practices.

Question & Answer :
However bash I instal a circumstantial interpretation of a expression successful homebrew? For illustration, postgresql-eight.four.four alternatively of the newest 9.zero.
TLDR: brew instal <a class="__cf_email__" data-cfemail="3c4c534f485b4e594f4d507c0412081208" href="/cdn-cgi/l/email-protection">[e-mail protected]</a> Seat reply beneath for much particulars.
*(I’ve re-edited my reply to springiness a much thorough workflow for putting in/utilizing older package variations with homebrew. Awareness escaped to adhd a line if you recovered the aged interpretation amended.)
Fto’s commencement with the easiest lawsuit:
- Cheque, whether or not the interpretation is already put in (however not activated)
Once homebrew installs a fresh expression, it places it successful a versioned listing similar /usr/section/Cellar/postgresql/9.three.1. Lone symbolic hyperlinks to this folder are past put in globally. Successful rule, this makes it beautiful casual to control betwixt 2 put in variations. (*)
If you person been utilizing homebrew for longer and ne\’er eliminated older variations (utilizing, for illustration brew cleanup), probabilities are that any older interpretation of your programme whitethorn inactive beryllium about. If you privation to merely activate that former interpretation, brew control is the best manner to bash this.
Cheque with brew information postgresql (oregon brew control postgresql <TAB>) whether or not the older interpretation is put in:
$ brew information postgresql postgresql: unchangeable 9.three.2 (bottled) http://www.postgresql.org/ Conflicts with: postgres-xc /usr/section/Cellar/postgresql/9.1.5 (2755 records-data, 37M) Constructed from origin /usr/section/Cellar/postgresql/9.three.2 (2924 records-data, 39M) * Poured from vessel From: https://github.com/Homebrew/homebrew/commits/maestro/Room/Expression/postgresql.rb # … and any much
We seat that any older interpretation is already put in. We whitethorn activate it utilizing brew control:
$ brew control postgresql 9.1.5 Cleansing /usr/section/Cellar/postgresql/9.1.5 Cleansing /usr/section/Cellar/postgresql/9.three.2 384 hyperlinks created for /usr/section/Cellar/postgresql/9.1.5
Fto’s treble-cheque what is activated:
$ brew data postgresql postgresql: unchangeable 9.three.2 (bottled) http://www.postgresql.org/ Conflicts with: postgres-xc /usr/section/Cellar/postgresql/9.1.5 (2755 records-data, 37M) * Constructed from origin /usr/section/Cellar/postgresql/9.three.2 (2924 information, 39M) Poured from vessel From: https://github.com/Homebrew/homebrew/commits/maestro/Room/Expression/postgresql.rb # … and any much
Line that the prima * has moved to the recently activated interpretation
(*) Delight line that brew control lone plant arsenic agelong arsenic each dependencies of the older interpretation are inactive about. Successful any circumstances, a rebuild of the older interpretation whitethorn go essential. So, utilizing brew control is largely utile once 1 needs to control betwixt 2 variations not excessively cold isolated.
- Cheque, whether or not the interpretation is disposable arsenic a pat
Particularly for bigger package tasks, it is precise most likely that location is a advanced adequate request for respective (possibly API incompatible) great variations of a definite part of package. Arsenic of March 2012, Homebrew zero.9 gives a mechanics for this: brew pat & the homebrew variations repository.
That variations repository whitethorn see backports of older variations for respective formulae. (Largely lone the ample and celebrated ones, however of class they’ll besides person respective formulae for postgresql.)
brew hunt postgresql volition entertainment you wherever to expression:
$ brew hunt postgresql postgresql homebrew/variations/postgresql8 homebrew/variations/postgresql91 homebrew/variations/postgresql9 homebrew/variations/postgresql92
We tin merely instal it by typing
$ brew instal homebrew/variations/postgresql8 Cloning into '/usr/section/Room/Faucets/homebrew-variations'... distant: Counting objects: 1563, carried out. distant: Compressing objects: a hundred% (943/943), performed. distant: Entire 1563 (delta 864), reused 1272 (delta 620) Receiving objects: a hundred% (1563/1563), 422.eighty three KiB | 339.00 KiB/s, performed. Resolving deltas: a hundred% (864/864), completed. Checking connectivity... performed. Tapped one hundred twenty five expression ==> Downloading http://ftp.postgresql.org/pub/origin/v8.four.19/postgresql-eight.four.19.tar.bz2 # …
Line that this has robotically tapped the homebrew/variations pat. (Cheque with brew pat, distance with brew untap homebrew/variations.) The pursuing would person been equal:
$ brew pat homebrew/variations $ brew instal postgresql8
Arsenic agelong arsenic the backported interpretation formulae act ahead-to-day, this attack is most likely the champion manner to woody with older package.
three) Attempt any expression from the ancient
The pursuing approaches are listed largely for completeness. Some attempt to resurrect any undead expression from the brew repository. Owed to modified dependencies, API modifications successful the expression spec oregon merely a alteration successful the obtain URL, issues whitethorn oregon whitethorn not activity.
Since the entire expression listing is a git repository, 1 tin instal circumstantial variations utilizing plain git instructions. Nevertheless, we demand to discovery a manner to acquire to a perpetrate wherever the aged interpretation was disposable.
a) historical occasions
Betwixt August 2011 and October 2014, homebrew had a brew variations bid, which spat retired each disposable variations with their respective SHA hashes. Arsenic of October 2014, you person to bash a brew pat homebrew/boneyard earlier you tin usage it. Arsenic the sanction of the pat suggests, you ought to most likely lone bash this arsenic a past hotel.
E.g.
$ brew variations postgresql Informing: brew-variations is unsupported and whitethorn beryllium eliminated shortly. Delight usage the homebrew-variations pat alternatively: https://github.com/Homebrew/homebrew-variations 9.three.2 git checkout 3c86d2b Room/Expression/postgresql.rb 9.three.1 git checkout a267a3e Room/Expression/postgresql.rb 9.three.zero git checkout ae59e09 Room/Expression/postgresql.rb 9.2.four git checkout e3ac215 Room/Expression/postgresql.rb 9.2.three git checkout c80b37c Room/Expression/postgresql.rb 9.2.2 git checkout 9076baa Room/Expression/postgresql.rb 9.2.1 git checkout 5825f62 Room/Expression/postgresql.rb 9.2.zero git checkout 2f6cbc6 Room/Expression/postgresql.rb 9.1.5 git checkout 6b8d25f Room/Expression/postgresql.rb 9.1.four git checkout c40c7bf Room/Expression/postgresql.rb 9.1.three git checkout 05c7954 Room/Expression/postgresql.rb 9.1.2 git checkout dfcc838 Room/Expression/postgresql.rb 9.1.1 git checkout 4ef8fb0 Room/Expression/postgresql.rb 9.zero.four git checkout 2accac4 Room/Expression/postgresql.rb 9.zero.three git checkout b782d9d Room/Expression/postgresql.rb
Arsenic you tin seat, it advises in opposition to utilizing it. Homebrew spits retired each variations it tin discovery with its inner heuristic and exhibits you a manner to retrieve the aged formulae. Fto’s attempt it.
# Archetypal, spell to the homebrew basal listing $ cd $( brew --prefix ) # Checkout any aged expression $ git checkout 6b8d25f Room/Expression/postgresql.rb $ brew instal postgresql # … putting in
Present that the older postgresql interpretation is put in, we tin re-instal the newest expression successful command to support our repository cleanable:
$ git checkout -- Room/Expression/postgresql.rb
brew control is your person to alteration betwixt the aged and the fresh.
b) prehistoric instances
For particular wants, we whitethorn besides attempt our ain digging done the homebrew repo.
$ cd Room/Faucets/homebrew/homebrew-center && git log -S'eight.four.four' -- Expression/postgresql.rb
git log -S seems to be for each commits successful which the drawstring 'eight.four.four' was both added oregon eliminated successful the record Room/Faucets/homebrew/homebrew-center/Expression/postgresql.rb. We acquire 2 commits arsenic a consequence.
perpetrate 7dc7ccef9e1ab7d2fc351d7935c96a0e0b031552 Writer: Aku Kotkavuo Day: Star Sep 19 18:03:forty one 2010 +0300 Replace PostgreSQL to 9.zero.zero. Signed-disconnected-by: Adam Vandenberg perpetrate fa992c6a82eebdc4cc36a0c0d2837f4c02f3f422 Writer: David Höppner Day: Star Whitethorn sixteen 12:35:18 2010 +0200 postgresql: replace interpretation to eight.four.four
Evidently, fa992c6a82eebdc4cc36a0c0d2837f4c02f3f422 is the perpetrate we’re curious successful. Arsenic this perpetrate is beautiful aged, we’ll attempt to downgrade the absolute homebrew set up (that manner, the expression API is much oregon little assured to beryllium legitimate):
$ git checkout -b postgresql-eight.four.four fa992c6a82eebdc4cc36a0c0d2837f4c02f3f422 $ brew instal postgresql $ git checkout maestro $ git subdivision -d postgresql-eight.four.four
You whitethorn skip the past bid to support the mention successful your git repository.
1 line: Once checking retired the older perpetrate, you quickly downgrade your homebrew set up. Truthful, you ought to beryllium cautious arsenic any instructions successful homebrew mightiness beryllium antithetic to the about new interpretation.
four) Manually compose a expression
It’s not excessively difficult and you whitethorn past add it to your ain repository. Utilized to beryllium Homebrew-Variations, however that is present discontinued.
A.) Bonus: Pinning
If you privation to support a definite interpretation of, opportunity postgresql, about and halt it from being up to date once you bash the earthy brew replace; brew improve process, you tin pin a expression:
$ brew pin postgresql
Pinned formulae are listed successful /usr/section/Room/PinnedKegs/ and erstwhile you privation to carry successful the newest modifications and updates, you tin unpin it once more:
$ brew unpin postgresql
