- For **Fish shell**:
Execute this interactively:
~~~ fish
set -Ux PYENV_ROOT $HOME/.pyenv
set -Ux fish_user_paths $PYENV_ROOT/bin $fish_user_paths
pyenv init --path | source
set -U fish_user_paths $PYENV_ROOT/bin $fish_user_paths
~~~
And add this to `~/.config/fish/config.fish`:
~~~ fish
status is-login; and pyenv init --path | source
~~~
If fish is not your login shell, also follow the bash/zsh instructions to add to ~/.profile.
- **Proxy note**: If you use a proxy, export `http_proxy` and `https_proxy` too.
3. **Add `pyenv init` to your shell** to enable shims and autocompletion.
