pyenv-which-ext

Integrate pyenv and system commands. This pyenv plugin automatically lookup system command if the specified command has not been installed in pyenv.

Installation

Installing as a pyenv plugin

Make sure you have pyenv 0.4.0 or later, then run:

git clone https://github.com/pyenv/pyenv-which-ext.git $(pyenv root)/plugins/pyenv-which-ext

Installing with Homebrew (for macOS users)

macOS users can install pyenv-which-ext with the Homebrew package manager.

This is the recommended method of installation if you installed pyenv with Homebrew.

$ brew install pyenv-which-ext

Or, if you would like to install the latest development release:

$ brew install --HEAD pyenv-which-ext

Usage

Nothing have to do manually. Just installing the plugin lets pyenv to fallback to the system version.

Examples

Let us say if you have 3 versions in pyenv.

$ pyenv versions
  system (set by /home/yyuu/.pyenv/version)
  3.4.0
  anaconda-1.9.2

If you use anaconda-1.9.2, you can use the curl installed in anaconda-1.9.2.

$ pyenv shell anaconda-1.9.2
$ pyenv which curl
/home/yyuu/.pyenv/versions/anaconda-1.9.2/bin/curl

Then, switch to the 3.4.0. Without pyenv-which-ext, the pyenv refuses to execute the curl since it is not installed in 3.4.0.

$ pyenv shell 3.4.0
$ pyenv which curl
pyenv: curl: command not found

The `curl' command exists in these Python versions:
  anaconda-1.9.2

So, it is the time to install pyenv-which-ext. This plugin lets pyenv to find the commands outside from pyenv if not found in current version(s).

$ pyenv shell 3.4.0
$ pyenv which curl
/usr/bin/curl
