我在本地开发了Django应用（django版本-3.0.5，python版本3.8.2，操作系统-Windows 10）。 在我的本地服务器上，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可以正常运行。我购买了用于生产部署的共享主机。这是一个 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
它显示以下错误：
$ pip install mysqlclient

我尝试了以下方案作为解决方案，但是没有用。
pip install MySQL-python并得到（ModuleNotFoundError）pip3 install MySQL-python并得到相同的错误（注意：'sudo'或'apt'命令不起作用）。
不允许我使用非官方的mysqlclient软件包。
该问题的解决方案是什么？
或者如何在没有mysqlclient软件包的情况下将我的应用程序与数据库连接？
答案 0 :(得分：0)
服务提供商解决的问题。他们能够使用管理员权限安装mysqlclient。
