我正在努力将我的Django 1.10应用程序部署到Heroku。正如前言一样，我正在使用Pycharm并且必须在某一时刻重命名我的项目，但它重构并在所有地方更改了名称，所以我希望这与问题无关。当我将此站点推送到Heroku时，我收到应用程序错误。
错误消息
在Heroku应用程序错误日志中，我看到：
2017-01-13T22:04:48.911324+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=secret-anchorage-68558.herokuapp.com request_id=71351a21-2264-4ca7-ad0a-1ae110d72ca7 fwd="162.247.89.174" dyno= connect= service= status=503 bytes=

它曾在我的计算机上本地工作，但现在当我尝试运行应用程序时，我得到：

remote: You may need to update application code to resolve this error.
remote: Or, you can disable collectstatic for this application:
remote:
remote: $ heroku config:set DISABLE_COLLECTSTATIC=1
remote:
remote: https://devcenter.heroku.com/articles/django-assets
remote: ! Push rejected, failed to compile Python app.
remote:
remote: ! Push failed

To https://git.heroku.com/secret-anchorage-68558.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/secret-anchorage-68558.git'
我尝试用
禁用COLLECTSTATICheroku config:set DISABLE_COLLECTSTATIC=0
似乎很有希望。它允许我将我的代码推送到Heroku，但是当我尝试
时heroku run python3 manage.py migrate
或
heroku open
我得到的错误与之前相同，并且不会在线显示。

任何想法我做错了什么？
答案 0 :(得分：2)
只需使用此
更改INSTALLED_APPS即可
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'catalog',
]
在
之后你会面临更多的错误如果您的生产中的DEBUG设置为False，那么您需要更改ALLOWED_HOSTS=[]
到ALLOWED_HOSTS = ['*']
添加settings.py文件
STATICFILES_STORAGE='whitenoise.django.GzipManifestStaticFilesStorage'
如果它不起作用，那么再做一次，看看步骤8和9 here.
