Manage multiple versins of Go on MacOS with Homebrew

MacOS-Multi-Version-Go-With-Homebrew.md

This process would likely apply to other Homebrew formula also.

First search for your desired package:

brew search go

You should get a list of results that include the below. Not "go" is very unspecific so you may get a lot of results:

==> Formulae
go ✔
go@1.10
go@1.11
go@1.9

Then install the desired version:

brew install go@1.10

Remember that you can have more than one package installed at the same time, but you cannot have them all available at the same time. So if you have the latest/generic go package already installed you need to unlink it first:

brew unlink go

And then you can link a different version:

brew link go@1.10

In some cases you may need to link them with the --force and --overwrite options:

brew link --force --overwrite go@1.10
