我在pythonanywhere上运行一个twitter应用程序,该应用程序在localhost开发服务器上完美运行,但是当我在pythonanywhere上运行它时,出现此错误：

是什么导致此错误？我应该在哪里看？
解决方法:
如果可能是由于pythonanywhere中的wsgi.py配置问题引起的,则在本地环境中,django可以很好地处理python路径和静态文件.
根据pythonanywhere中的part部署文档：
>在wsgi.py中为sys.path添加正确的路径
假设您的Django设置文件位于/home/my_username/projects/my_project/settings.py’
path = '/home/my_username/projects'
if path not in sys.path:
sys.path.append(path)
os.environ['DJANGO_SETTINGS_MODULE'] = 'my_project.settings'
from my_project.myapp.models import Kitchen, Sink
请注意：需要my_project前缀.
2.静态文件应该处理好
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()
根据文件检查这两点应解决
