我正在关注这个 DjangoGirls 教程:http://tutorial.djangogirls.org/en/deploy/README.html
当我尝试打开我的应用程序的/admin 页面时，因为教程指出:
"Since we only created the admin view for the app so far, add admin/ to the url (e.g. https://djangogirlsblog.herokuapp.com/admin/) to see a working page of our web app."
我仍然收到以下浏览器消息:
Application Error An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details.
这是我的项目布局:
djangogirls
|--mysite/
|--blog/
|--db.sqlite3
|----manage.py
|----mysite/
|--myvenv/
|--Procfile
|--requirements.txt
|--runtime.txt
|--.gitignore
这些是 .gitignore 的内容:
myvenv
__pycache__
staticfiles
local_settings.py
db.sqlite3
*.py[co]
*.pyc
这些是我的 mysite/wsgi.py 的内容
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
application = get_wsgi_application()
from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)
这些是Procfile的内容是
网络:gunicorn djangogirls.wsgi
教程说把mysite.wsgi拷出来，但是我在另一个帖子里看到应该是project_name.wsgi，所以就改了。
runtime.txt: python-2.7.6
要求.txt:
dj-database-url==0.3.0
Django==1.8
gunicorn==19.3.0
whitenoise==1.0.6
psycopg2==2.5.4
我知道这是一篇很长的帖子，我提前为此道歉，我想提供更多的信息而不是不够的，我不完全明白在这种情况下我应该关注哪些重要的事情!
这是我的 heroku 日志:

这似乎是本教程中比较困难的阶段之一，我似乎无法弄清楚这个错误到底意味着什么......提前感谢任何可以提供帮助的人，我真的很感激!
请您参考如下方法:
如果您在根目录中项目文件夹，那么您必须提供准确的路径，以便 gunicorn 可以更好地服务..:)
像 web: gunicorn --pythonpath app app.wsgi
了解更多信息 pythonpath
