MySQL pip3 安装错误：元数据生成失败

Question

我尝试更新 pip 并安装不同的软件包，但似乎没有任何效果。 我不确定我是否必须在 konsole 或 alacritty 中运行命令，但我们将不胜感激。 我用fedora顺便说一句

 sh-5.1$ pip3 install mysql

  note: This error originates from a subprocess, and is likely not a problem with pip.

Answer 1

在安装之前，您必须解决依赖关系。

sudo apt-get install python3-dev libmysqlclient-dev

然后在虚拟环境中：

pip3 install mysqlclient

然后

  pip3 install mysql

它应该工作
