错误：
WARNING: Image for service django was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.

CMD source develvenv/bin/activate
起初，我以为虚拟环境是问题
所以，我尝试添加CMD source develvenv/bin/activate，但错误仍然没有消失。.
据我所知，这种错误不是Django本身的问题。我认为虚拟环境会引起问题。
你的主意如何？
