当我尝试启动新的Django项目并运行服务器时，我有
"SOURCE /lo-fi-radio HTTP/1.0" 404 1987，但这是一个全新的空项目，带有自己的virtualenv。 lo-fi-radio是我上一个项目的根目录。还有另一个奇怪的错误。

----------------------------------------
pip freeze在virtualenv给出
Django==2.2.6
psycopg2==2.8.3
pytz==2019.2
sqlparse==0.3.0
我什至都没猜到是什么问题，因为它是在新的空项目中发生的，而且我没有从以前的项目中复制任何文件。
UPD：重新安装virtualenv和virtualenvwrapper没有帮助
