How can I brew link a specific version?
homebrew
Solution
This is probably the best way as of 11.1.2022:
To install a specific version, e.g. postgresql 9.5 you simply run:
$ brew install postgresql@9.5
To list the available versions run a search with @:
$ brew search postgresql@
==> Formulae
postgresql postgresql@11 postgresql@13 postgresql@9.5 qt-postgresql
postgresql@10 postgresql@12 postgresql@9.4 postgresql@9.6 postgrest
==> Casks
navicat-for-postgresql
DEPRECATED in Homebrew 2.6.0 (December 2020):
The usage info:
Usage: brew switch <formula> <version>
Example:
brew switch mysql 5.5.29
You can find the versions installed on your system with `info`.
brew info mysql
And to see the available versions to install, you can provide a dud version number, as brew will helpfully respond with the available version numbers:
brew switch mysql 0
Update (15.10.2014):
The `brew versions` command has been removed from brew, but, if you do wish to use this command first run `brew tap homebrew/boneyard`.
The recommended way to install an old version is to install from the `homebrew/versions` repo as follows:
$ brew tap homebrew/versions
$ brew install mysql55
