这种情况是我想使用virtualenv自动执行我的部署过程。我在一个git仓库中有一个python项目。我使用jenkins来自动化所有的东西。里面一个詹金斯建设，我做到以下几点：virtualenv pip安装mysql-python失败
- 连接到远程测试服务器
- 创建一个空的virtualenv
- 下载我的项目（GIT克隆）
- 安装依赖 - 进入virtualenv中
最后一步失败。那里有python 2.6.6。我运行. bin/activate来输入virtualenv并运行pip install mysql-python来安装我的依赖项。以下是我得到的控制台输出：

这里有很多C错误我会省略。

和最终就是这样：

这是怎么回事？这是很奇怪的，因为在服务器上安装了全球MySQLdb的：
