【问题标题】：Error installing mysqlclient for python on Ubuntu 18.04在 Ubuntu 18.04 上为 python 安装 mysqlclient 时出错
【发布时间】：2023-04-05 08:26:01
【问题描述】：

我在 Ubuntu 上安装了 Python 2.7.15rci 和 Python 3.6.7。当我在 virtualenv 上执行 'pip list' 时，它返回给我：

Django (2.1.5)
pip (9.0.1)
pkg-resources (0.0.0)
pytz (2018.9)
setuptools (39.0.1)
wheel (0.32.3)

我正在尝试安装 mysqlclient (pip install mysqlclient) 并返回错误。

  unable to execute 'x86_64-linux-gnu-gcc': No such file or directory
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

所以，我尝试了不同的方法，例如：

sudo apt-get install python-dev
sudo apt-get install python3-dev
sudo apt-get install libmysqlclient-dev

还有更多...但它们都不适合我，问题仍然存在。
有什么建议吗？

谢谢！

【问题讨论】：

您需要根据文档安装default-libmysqlclient-dev，而不是libmysqlclient-dev。
我也安装了default-libmysqlclient-dev，但是还是不行……
你说你试过sudo apt-get install python-dev python3-dev，那些还在安装吗？还是每次都卸载？所有这些都需要安装。
这很奇怪，我刚刚在 Ubuntu 18.0.4 上使用默认 python (3.6) 安装它，没有任何问题。完全通过安装python3-dev gcc default-libmysqlclient-dev。这些就足够了。
我不知道为什么我没有安装这些库，但我安装了libssl-dev 并且它起作用了！谢谢！ ;)
