Hello, friends!

As I have [mentioned before]({{ site.url }}/2020/09/21/working-with-pyenv-on-macos/), I am using pyenv to manage multiple Python installations, but since I installed some Hombrew formulae that depend on [email protected] I decided to uninstall Python 3 installed via pyenv and use the one from Homebrew.

So here I will share a quick guide on how I accomplished that.

  1. If you've installed the latest Python 3.9 version via pyenv, uninstall it by running uninstall and then rehash

    pyenv uninstall 3.9.X
pyenv rehash

  2. Create a symlink at ~/.pyenv/versions

    $ cd ~/.pyenv/versions
$ ln -sfv "$(brew --prefix [email protected])" 3.9
$ ls -al
total 0
drwxr-xr-x  4 cesarcoatl  staff  128 Aug 31 07:51 .
drwxr-xr-x  6 cesarcoatl  staff  192 Jun  8 10:58 ..
drwxr-xr-x  6 cesarcoatl  staff  192 Aug 31 07:48 2.7.18
lrwxr-xr-x  1 cesarcoatl  staff   25 Aug 31 07:51 3.9 -> /usr/local/opt/[email protected]

  3. If you wish to also include the include directory, run the following

    $ cd "$(brew --prefix [email protected])"
$ ln -sfv Frameworks/Python.framework/Versions/3.9/include/python3.9 include
include -> Frameworks/Python.framework/Versions/3.9/include/python3.9
$ ls -al
total 64
drwxr-xr-x  14 cesarcoatl  staff    448 Aug 31 07:43 .
drwxr-xr-x   3 cesarcoatl  staff     96 Jul  3 09:36 ..
drwxr-xr-x   3 cesarcoatl  staff     96 Jun 28 01:57 .brew

drwxr-xr-x  19 cesarcoatl  staff    608 Aug 31 07:50 bin
lrwxr-xr-x   1 cesarcoatl  staff     58 Aug 31 07:43 include -> Frameworks/Python.framework/Versions/3.9/include/python3.9
drwxr-xr-x   3 cesarcoatl  staff     96 Jun 28 01:57 lib
drwxr-xr-x   4 cesarcoatl  staff    128 Jun 28 01:57 libexec
drwxr-xr-x   3 cesarcoatl  staff     96 Jun 28 01:57 share

  4. Create symlinks for idle, pip, python and wheel at the following location:

    $ cd "$(brew --prefix [email protected])/bin"
$ ln -sfv idle3 idle
idle -> idle3
$ ln -sfv pip3 pip 
pip -> pip3
$ ln -sfv python3 python
python -> python3
$ ln -sfv wheel3 wheel
wheel -> wheel3

  5. Once that's done, run pyenv rehash as recommended by pyenv whenever you install new versions

    pyenv rehash

  6. Now, you're ready to verify all versions managed by pyenv, and select a global, local, or shell version

    $ pyenv versions
* system (set by /Users/cesarcoatl/.pyenv/version)
  2.7.18
  3.9

  7. If you want to set 3.9 as global, just run by running

    pyenv global 3.9

  8. Verify your selection by running

    $ pyenv versions
  system
  2.7.18
* 3.9 (set by /Users/cesarcoatl/.pyenv/version)

  9. And now when I run python --version I get the following output:

    $ python --version
Python 3.9.6

And that's it! You've done it!

Thanks for reading and happy coding!
