Python虚拟环境下pip安装MySQL-Python导致“RuntimeError: 超出最大递归深度”

Question

我设置了一个虚拟环境，然后尝试通过 pip 安装 MySQL-Python（在激活环境后）。我的 requirements.txt 文件内容如下：

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，最后一行输出是：

RuntimeError: maximum recursion depth exceeded

正如某个帖子提到的，我甚至运行了这个命令来升级我的 distribute：

easy_install distribute==0.6.28

结果还是不行。我的 Python 版本（在虚拟环境中）是 2.7.6，机器是 Ubuntu 14.04。

更新：错误追踪信息如下：

Answer 1

我也遇到这个问题！

这是我设置的一些说明：

• 使用的是 Ubuntu 13.10
• 通过 apt-get 安装了 Python-MySQLdb 和 libmysqlclient-dev

我还发现了这个，我怀疑这可能是根本原因：

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：

看起来我在没有设置 CFLAGS 或 CPPFLAGS 环境变量的情况下，仍然会遇到这个问题（MySQL-Python 1.2.4）。1.2.5 对我来说是可以的。
