将 Django 应用程序部署到 Heroku 时出错

Question

I am trying to deploy a django app but I am getting a push rejected error(Traceback attached). I am using whitenoise to handle the static files and done the correct configuration in settings.py file. This error has really been bugging me .

-----> $ python manage.py collectstatic --noinput
       Traceback (most recent call last):

       See traceback above for details.
       You may need to update application code to resolve this error.
       Or, you can disable collectstatic for this application:
          $ heroku config:set DISABLE_COLLECTSTATIC=1

 !     Push failed

Answer 1

在您的开发环境中，运行pip freeze > requirements.txt这将添加您当前安装的所有模块，并且假设您的开发环境具有其所有依赖项，将使 Heroku 能够安装所有需要的模块。
