### Installing with Homebrew (for OS X users)
Mac OS X users can install python-build with the [Homebrew](http://brew.sh)
package manager. This will give you access to the `python-build` command. If you
have pyenv installed, you will also be able to use the `pyenv install` command.
*This is the recommended method of installation if you installed pyenv with
Homebrew.*
brew install pyenv
Or, if you would like to install the latest development release:
brew install --HEAD pyenv
## Usage ## Usage
Before you begin, you should ensure that your build environment has the proper
system dependencies for compiling the wanted Python Version (see our [recommendations](https://github.com/yyuu/pyenv/wiki#suggested-build-environment)).

### Building as `--enable-shared` ### Applying patches to Python before compiling
Both `pyenv install` and `python-build` support the `--patch` (`-p`) flag that
signals that a patch from stdin should be applied to Python, Jython or PyPy
source code before the `./configure` and compilation steps.
Example usage:
```sh
# applying a single patch
$ pyenv install --patch 2.7.10 < /path/to/python.patch
# applying a patch from HTTP
$ pyenv install --patch 2.7.10 < <(curl -sSL http://git.io/python.patch)
# applying multiple patches
$ cat fix1.patch fix2.patch | pyenv install --patch 2.7.10
