【问题描述】：

我试图让 mysql 与 django 一起工作。使用 pip 在 virtualenv 中安装所需的绑定会产生错误。

pip install MySQL-python

软件包已下载，但我收到以下错误消息，指出缺少头文件 my_config.h。

以下软件包已安装和更新。

yum install -y gcc gcc-c++ libxml2-devel libxslt-devel

我也跑了

yum groupinstall "Development Tools" "Development Libraries"

问题仍然存在。是包有问题还是缺少任何依赖项？

【问题讨论】：

yum install mysql-devel
是的。它解决了这个问题。谢谢。

标签： python mysql django python-2.7 pip

【解决方案1】：

你需要安装mysql库的头文件。我不知道你的发行版，在 Ubuntu 上，包名是 libmysqlclient-dev。

顺便说一句，如果开始一个新项目，我会推荐 PostgreSQL 而不是 MySQL，因为对 MySQL 的支持充其量是不确定的。

编辑：原来事情发生了变化，现在有bindings for Python 3

【讨论】：

是的，安装 yum 对应的 mysql-devel 解决了这个问题。我正在运行 MySQL，因为我的项目涉及许多读取操作和 PostgreSQL，我了解到读取操作较慢。

【解决方案2】：

yum info mysql-devel

如果没有安装，请安装

yum install mysql-devel

现在试试

sudo pip install mysql-python

【讨论】：

【解决方案3】：

安装 mysql-dev 也解决了我的问题。非常感谢！

【解决方案4】：

yum install mysql-devel

然后

pip install MySQL-python
