【问题描述】：

当我尝试在 virtualenv (pip install mysql-python) 中安装 MySQL-python 时，我收到以下错误（截断到最后几行）

_mysql.c: At top level:
_mysql.c:2551: error: ‘_mysql_ConnectionObject’ has no member named ‘open’    
_mysql.c:2558: error: ‘_mysql_ConnectionObject’ has no member named ‘converter’

谷歌搜索告诉我我需要安装 python-devel，虽然当我运行 yum install python-devel 时我得到了

Package python-devel-2.6.6-52.el6.x86_64 already installed and latest version
Nothing to do

我在安装了 python 2.6 和 2.7 的 CentOS 6.5 机器上。我在我的 virtualenvs 中使用 python 2.7。我在运行pip install mySQL-python 时激活了 virtualenv。

我尝试在激活和停用 virtualenv 的情况下运行 yum install python-devel，两次都显示“已安装”消息。

这是否意味着 python 27 安装没有得到python-devel 安装？

另一个线程建议尝试yum install mysql-devel.x86_64，尽管这给出了

Resolving Dependencies

--> Processing Dependency: mysql = 5.1.73-3.el6_5 for package: mysql-devel-5.1.73-3.el6_5.x86_64

               mysql = 5.1.73-3.el6_5
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

（使用--skip-broken 不起作用，它只是跳过它）

【参考方案1】：

已解决：我需要运行 sudo yum --enablerepo=remi install mysql-devel

然后，运行 pip install MySQL-python 工作（激活了我的 virtualenv）
