pyenv-pip-migrate

pyenv-pip-migrate is a pyenv plugin that provides a pyenv migrate command to migrate pip package from a Python version to another.

Installation

Installing as a pyenv plugin

Installing pyenv-pip-migrate as a pyenv plugin will give you access to the pyenv migrate command.

$ git clone https://github.com/pyenv/pyenv-pip-migrate.git $(pyenv root)/plugins/pyenv-pip-migrate

This will install the latest development version of pyenv-pip-migrate into the $(pyenv root)/plugins/pyenv-pip-migrate directory. From that directory, you can check out a specific release tag. To update pyenv-pip-migrate, run git pull to download the latest changes.

Installing with Homebrew (for macOS users)

macOS users can install pyenv-pip-migrate with the Homebrew package manager. This will give you access to the pyenv-migrate command. If you have pyenv installed, you will also be able to use the pyenv migrate command.

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

$ brew install pyenv-pip-migrate

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

$ brew install --HEAD pyenv-pip-migrate

Usage

Using pyenv migrate with pyenv

pyenv-pip-migrate uses pip freeze to dump all installed packages in a Python version, and then tries to pip install them into another version.

Let's say if you have following two versions in pyenv.

$ pyenv versions
* 2.7.4 (set by /home/yyuu/.pyenv/version)
  2.7.5
$ pip freeze
distribute==0.6.43
nose==1.3.0
wsgiref==0.1.2

To migrate installed packages from 2.7.4 to 2.7.5, use pyenv migrate.

$ pyenv migrate 2.7.4 2.7.5
$ pyenv global 2.7.5
$ pip freeze
distribute==0.6.43
nose==1.3.0
wsgiref==0.1.2
