Heroku run python抛出错误ModulenotfoundError

Question

我尝试运行heroku run Python manage.py migrate

抛出错误ModulenotfoundError no module named django

还有

ImportError: Could not import django.are you sure it's installed
and available on you Python path environment variable? 
Did you forget to activate a virtual environment?

我尝试了所有这些，我检查我的django它工作正常，

如果我尝试Python manage.py run server服务器运行没有任何问题。
