我正在AWS实例（amazon2 64位，Linux / 4.14.128-112.105.amzn2.x86_64）上部署Django应用程序。我花了很多时间在堆栈溢出中查找和搜索，而没有找到解决方案。
我的问题：正确安装mysqlclient。
错误：
mod_wsgi (pid=14418): Failed to exec Python script file '/var/www/html/project_x/project_x/wsgi.py'.
mod_wsgi (pid=14418): Exception occurred processing WSGI script '/var/www/html/project_x/project_x/wsgi.py'.

Did you install mysqlclient?
我已经安装了所有东西，但是没有用。
我在项目文件夹中创建了虚拟环境：
$ virtualenv projectenv --python=python3.7
$ source projectenv/bin/activate
之后，我用pip安装了插件：
$ pip list
Package Version
----------- -------
Django 2.2.5
mysqlclient 1.4.4
pip 19.2.3
pytz 2019.2
setuptools 41.2.0
sqlparse 0.3.0
wheel 0.33.6
如您所见，软件包已正确安装。还将安装msqlclient。我不知道该怎么办，我已经咨询了很多有关Stackoverflow的帖子，但是都没有解决我的问题。
