python - django.db.utils.OperationalError：（2013年，“握手时与MySQL服务器的连接丢失：读取ini

我正在使用django开发一个应用程序以将其推送到Heroku，并且尝试将mysql中的数据库迁移到heroku时，我安装了mysql-python，并且在尝试运行服务器时遇到了以下错误：

django.db.utils.OperationalError：（2013年，“握手时与MySQL服务器的连接丢失：读取初始通信数据包”，系统错误：0”）

（我启用了虚拟环境）。
奇怪的是，即使我已经安装了该软件包，该软件包也安装了python。
我发现它没有安装django和以前安装的几个模块，甚至是pip！

我重新安装了模块，但是现在当我运行服务器时，上面出现了该错误。
如果我从另一个应用程序目录运行服务器，则数据库运行良好。
它可能与我安装在目录中的内容有关，或者可能被奇怪的软件包覆盖了吗？

这是我的点冻结结果：

certifi==2019.6.16<br>
dj-database-url==0.5.0<br>
Django==2.2.3<br>
django-heroku==0.3.1<br>
gunicorn==19.9.0<br>
mysql-connector-python==8.0.16<br>
mysqlclient==1.4.2.post1<br>
protobuf==3.6.0<br>
psycopg2==2.8.3<br>
PyMySQL==0.9.3<br>
python-decouple==3.1<br>
pytz==2019.1<br>
six==1.12.0<br>
sqlparse==0.3.0<br>
whitenoise==4.1.2<br>
wincertstore==0.2<br>

现在，我将删除该项目并尝试重新构建它，只要我了解，搞砸该项目的原因就是我尝试安装mysql-python。
