    # Setting up Python on OSX
    # Awesomely easy virtualenvs on OSX using pyenv and direnv

    Never forget to activate that virtualenv or set that environment variable ever again...

    ## Install

    1. Install pyenv
    brew install pyenv

    brew install pyenv

    2. Install a few different pythons

    pyenv install 3.6.0
    pyenv install 3.5.2
    pyenv install 2.7.who-cares

    3. Install direnv

    brew install direnv

    4. If you're using zsh add the following to your `~/.zshrc`:

    echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc

    5. If you're using bassh add the following to your `~/.bashrc`:

    echo 'eval "$(direnv hook bash)"' >> ~/.bashrc

    6. Copy `.direnvrc` into `~/`

    You now have everything setup to *use* direnv.

    ## In use

    Now, time to actually use it.

    1. Create a directory, I usually put this in `~/workspace`, others prefer `!/projects`.

    mkdir ~/projects/w00t

    2. Create the file `~/projects/w00t/.envrc`

    echo "use python 3.6.0" > ~/projects/w00t/.envrc
    echo "export AN_ENVIRONMENT_VARIABLE=1" >> ~/projects/w00t/.envrc

    3. Go into that directory and say "yes, I trust this .envrc". You only need to do this when your `.envrc` file changes.

    cd ~/projects/w00t
    direnv allow
    This will cause a new python virtualenv to be created in `~/projects/w00t/.direnv`

    Now anytime you `cd` into `~/projects/w00t` or a directory below that the virtualenv will automatically be enabled for you.

    w00t!
    This will cause a new python virtualenv to be created in `~/projects/w00t/.direnv`

    Now anytime you `cd` into `~/projects/w00t` or a directory below that the virtualenv will automatically be enabled for you and environment variable `AN_ENVIRONMENT_VARIABLE` will be set.

    w00t!
