无法在 linux 共享主机服务器上安装 'mysqlclient'。 'Failed to build wheel for mysqlclient'

Question

我在本地开发了一个Django App (django版本-3.0.5,python版本3.8.2,OS-Windows10)。在我的本地服务器上，我使用以下命令安装了 'mysqlclient'。

python -m pip install mysqlclient

该应用程序在我的本地服务器上完全正常运行。我为生产部署购买了共享主机。它是一个 linux 服务器（django 版本 - 3.0.5，python 版本 3.7.3）。我在 virtualenv 上安装了 Django 和 Python，但无法安装 'mysqlclient'。我使用了以下命令。

pip install mysqlclient

显示错误如下：

$ pip install mysqlclient

我尝试了以下方案作为解决方案，但没有奏效。

升级'pip'版本
升级'wheel'版本
试图通过Github
pip install MySQL-python 并得到 (ModuleNotFoundError)
pip3 install MySQL-python 得到同样的错误

(注意: 'sudo' 或 'apt' 命令无效。

我不允许使用非官方的 mysqlclient 包。

这个问题的解决方案是什么？

或者如何在没有 mysqlclient 包的情况下将我的应用程序连接到数据库？

Answer 1

问题由服务商解决。他们能够使用他们的管理员权限安装 mysqlclient。
