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。因为我想将我的 Django 项目连接到数据库。 当我想安装必要的包时，除了MySQLClient之外，每个人都安装。 它还给出一个错误：

Collecting mysqlclient

我不明白这个错误，我不知道它说什么。 无论我如何搜索，我都没有找到任何有用的东西。 感谢您的帮助。

Answer 1

我在安装 mysqlclient

error: subprocess-exited-with-error 时遇到以下类型的错误

1. （运行 setup.py install for
   mysqlclient没有运行成功）

2. Python 错误：命令“X86_64-Linux-Gnu-Gcc”失败，退出状态为 1（含代码示例）

---

让我们使用以下命令解决此问题：

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用，您至少可以尝试一下。我希望它有帮助。
谢谢！

Answer 2

我发现我尝试安装 MySQLclient 的主机必须由提供商配置为 Python 3.9
但因为我比较着急，没能等到主机配置好，所以我在Python 3.7上运行项目并没有出现问题。
