When working on Python projects, pyenv
is a
great python environment / version manager, especially on macOS wherein you
cannot easily control the python system version.
I’d recommend to install it with homebrew (brew install pyenv
).
The upstream documentation is great. The commands you’ll typically use are:
pyenv versions
: list all installed versionspyenv global <version>
: set a specific python version for your whole systempyenv local
: set a specific python version only for a specific project (directory)
And then it’s handy to add the following blurb to your shell rc file to make
pyenv
work properly out-of-the-box:
# pyenv: https://github.com/pyenv/pyenv
if hash pyenv >/dev/null 2>&1; then
export PYENV_ROOT="$HOME/.pyenv"
path_munge "$PYENV_ROOT/bin"
eval "$(pyenv init -)"
fi
Note that path_munge
is a custom function, it merely appends the given
argument to the $PATH
.
