django_heroku ModuleNotFoundError虽然正确安装

Question

我正在制作一个django项目并使用css文件，但是在部署到heroku时我得到了：

ModuleNotFoundError: No module named 'django_heroku'

我已经为django-heroku安装了所有东西...最后说：

Or, you can disable collectstatic for this application:
remote:
remote:           $ heroku config:set DISABLE_COLLECTSTATIC=1

但是我正在使用css文件并通过禁用此applicaton错误发生 请帮助，,,我几乎放弃了我尝试了2天的机会

这里是我执行git push heroku master时发生错误的程序
