我在pythonanywhere上运行一个 twitter 应用程序，该应用程序在 localhost 开发服务器上运行良好，但是当我在pythonanywhere上运行它时，我得到了这个错误：

什么可能导致此错误？我应该去哪里看？

如果可能是由 pythonanywhere 中的 wsgi.py 配置问题引起的，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 部署文档中的这一部分：

  1. 在 wsgi.py 中添加 sys.path 的正确路径
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：my_project 前缀是必需的。

2.static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该解决这个问题

我的应用程序有完全相同的问题......问题原来是文件权限。如果app目录没有执行权限，则导入失败。
