为什么没有安装mySQLclient

Question

我想通过终端在我的Cpanel主机上安装MySQLclient包。因为我想把我的Django项目连接到数据库。当我想安装必要的软件包时，除了MySQLClient，其他人都会安装。它还给出了一个错误：

我不理解这个错误，也不知道它说了什么。不管我找了多少，都没有找到任何有用的东西。谢谢你的帮助。

我在安装mysqlclient 时遇到以下类型的错误

1. 错误：子进程退出并出现错误(正在为运行setup.py installmysqlclient未成功运行(

2. Python错误：命令"X86_64-Linux-Gnu-Gcc"失败，退出状态为1，代码示例为

让我们使用以下命令来解决这个问题：

sudo apt-get install gcc python3.x-dev # choose correct python version
sudo apt-get install libxml2-dev libxslt1-dev

这个解决方案对我有效，你至少可以试试。我希望它能有所帮助。谢谢

Answer 2

我发现我试图安装MySQLclient的主机必须由Python 3.9的提供程序配置但因为我很着急，等不及主机配置，所以我在Python 3.7上运行了这个项目，没有出现任何问题。
