cc1：错误：在Mac 10.7.5上安装python-mysql时出现无法识别的命令行选项“ -Wno-null-conversion”

Question

此错误中断了我在Mac 10.7.5上的python-mysql安装。步骤如下

1. 安装的python是2.7.1，mysql是5.6.11的64位。
2. 正在安装的python-mysql是1.2.4，也尝试过1.2.3
3. 安装配置

   1) sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql
   

   2) Edit the setup_posix.py and change the following mysql_config.path = “mysql_config” to mysql_config.path = “/usr/local/mysql/bin/mysql_config”
   3) sudo python setup.py build
   

这是构建的堆栈跟踪

欢迎您提出建议和想法。谢谢。

尝试删除cflags -Wno-null-conversion -Wno-unused-private-field在

/usr/local/mysql/bin/mysql_config.
