Install pyenv, but don't use shims and pyenv init to prevent pyenv from
intercepting common executables with its shim. e.g. if you have tox installed
as a pex standalone executable, but also in a pyenv-managed virtual
environment, pyenv will intercept a call to tox.
Use the pyenv installer with curl https://pyenv.run | bash.
Remove any eval of pyenv init or pyenv virtualenv-init that the installer
added to ~/.bash_profile. Keep or add export PATH="$HOME/.pyenv/bin:$PATH"
in ~/.bash_profile.
pyenv will only be used to manage installation of different
versions of Python. e.g. install Python 3.8.8 with pyenv install 3.8.8. Then
add this version's location to your path to make it the default Python.
Restart your shell to update PATH.
Now install poetry.
curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3
And add poetry bash completions (assuming homebrew on a Mac here):
poetry completions bash > $(brew --prefix)/etc/bash_completion.d/poetry.bash-completion
echo "source $(brew --prefix)/etc/bash_completion.d/poetry.bash-completion" >> ~/.bash_profile
In the end, the cumulative changes to ~/.bash_profile should look like this:
export PATH="$HOME/.pyenv/bin:$PATH"
export PATH="$HOME/.pyenv/versions/3.8.8/bin:$PATH"
export PATH="$HOME/.poetry/bin:$PATH"
source /usr/local/etc/bash_completion.d/poetry.bash-completion
