Python virtualenv pip install MySQL-Python 导致“RuntimeError：超出最大递归深度”

Question

我设置了一个 virtualenv，然后尝试使用 pip (after activating env) 安装 MySQL-Python。我的requirements.txt如下：

MySQL-python==1.2.5
argparse==1.2.1
pymongo==2.6.3
wsgiref==0.1.2

当我运行pip install -r requirement.txt 时。我得到一些输出，最后一行是：

RuntimeError: maximum recursion depth exceeded

正如一篇文章中提到的，我什至运行了这个命令来升级我的分发：

easy_install distribute==0.6.28

即使这样也没有用。我的 python 版本（在 env 中）是 2.7.6，机器是 Ubuntu 14.04

更新：堆栈跟踪如下：

Answer 1

也得到这个！

我的设置中的一些注意事项：

• Ubuntu 13.10
  • Python-MySQLdb 和 libmysqlclient-dev 都是通过 apt-get 安装的

我也看到了这个，我怀疑这是根本原因：

x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-Qunused-arguments’
x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-Qunused-arguments’

编辑：

看起来我仍然得到这个（MySQL-Python 1.2.4），没有设置 CFLAGS 或 CPPFLAGS 环境变量。 1.2.5 适合我。
