我正在努力在系统范围内或在安装了 MariaDB 10 的 Ubuntu 14.04 上的 venv 中安装 mysql-python pip。还尝试使用 MariaDB 5.5 并得到相同的错误。安装了 vanilla mysql-server 时我没有这个问题。
我通过 apt-get 安装了以下内容:
最初我认为这是将它安装到 venv 中的问题，但我随后注意到 mysql-python 也不会在系统范围内安装。以下是我用来安装在 venv 中的 cmds。
virtualenv venv
. venv/bin/activate
pip install mysql-python==1.2.5

请您参考如下方法:
您需要安装 OpenSSL 的开发库。如果您的发行版为开发库提供了单独的包，则它可以是 libssl-dev、libssl-devel。或者如果没有安装完整的 openssl 包。

libssl-dev提供这两个库的包。
