渲染时出现ImportError:没有名为app的模块

作者:互联网

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
