# pyenv-pip-migrate
pyenv-pip-migrate is a [pyenv](https://github.com/pyenv/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](http://brew.sh) 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
