python - Linux 上的 Django MySQLClient pip 编译失败

Question

自 v1.8 起的 Django 文档建议为框架使用 mysqlclient 连接器。我正在尝试使用 Python 3.4 在 Ubuntu 14.04 上 pip 安装软件包，但遇到了一个我无法找到引用的 GCC 错误。我不是编译软件方面的专家，所以希望有人能看到解决方案。

我认为我遇到了链接错误。我已经安装了发行版特定的 mysql header ，但看起来它们只适用于 Python 2.7.x。

不确定其中有多少是有用的，所以对于冗长的粘贴表示歉意，但这是错误日志:

Answer 1

看起来你缺少 zlib；你会想要安装它:apt-get install zlib1g-dev

我还建议阅读自述文件并确认您满足所有其他依赖项:https://github.com/dccmx/mysqldb/blob/master/README

此外，我建议使用 mysqlclient 而不是 MySQLdb 作为 MySQLdb 和 what Django recommends 的分支。 .
