You can actually `brew search python@` to see the available versions (major/minor only, not patch) and then `brew install python@3.7` to install an older version. Caveat is that this depends on someone having made a separate formula, under the correct versioned naming scheme, and uploaded it to homebrew. There doesn't seem to be a python2 formula, for example. I think it's a difference in philosophy? Brew does a "good enough" job for the most common use case, supplementing Apple's janky *nix environment with commonly-needed tools, without a built-in package manager. It doesn't try to do complex simultaneous versions... in my (admittedly limited) experience, if you need to do that, you either do that in something like a project-based setup (npm/composer) or in a VM/container with its own packages. In your situation, when you have multiple pythons running in the same environment, how does anyone given script know which one to call? What's a better way of doing this? |
