MAMPでPythonのWebアプリケーション開発を行っているのですが, PythonのMySQL-Pythonがエラーでインストールできません.
調べてみたところMySQL-Pythonのインストールに関してエラーが発生するケースが多いようですが, 色々調べて試してみたもののうまくいきません.  
以下, ターミナルのログです.

## Pythonのバージョン

2.7.10です.

```

    $ python --version
    Python 2.7.10

question
python mysql macos pip
macOS Sierra 10.12.4でMySQL-Pythonがインストールできない (pip)
`pip freeze` で pyOpenSSL が入っていることは確認したのですが, どうやらバージョンが古すぎたようです.

`brew unlink openssl && brew link openssl --force` を実行したところ新しいバージョンにリンクされたようで,
その後は `$ sudo pip install MySQL-Python` でインストールに成功しました.
