Sys.path修改或更复杂的问题？
我在正确导入 appengine 上的模块时遇到问题。我的应用程序通常使用 django 和 app-engine-patch，但这部分是仅使用 webapp 框架的任务队列。
我需要导入 django 设置才能使应用程序正常工作。
我的脚本开头为：
import os
import sys
sys.path.append('common/')
# Force Django to reload its settings.
from django.conf import settings
settings._target = None
# Must set this env var before importing any part of Django
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
我总是收到此错误，或相关的内容：
<type 'exceptions.ImportError'>: No module named ragendja.settings_pre
因为 settings.py 文件开头为
from ragendja.settings_pre import *
我认为我需要再次将 ragendja 添加到 sys.path 但我进行了几次尝试，但没有成功。
这是我的目录：
project/
app.yaml
setting.py
common/
appenginepatch/
ragendja/
setting_pre.py
myapp/
script.py
这只是 sys.path 问题吗？我需要如何使用正确的语法修改它？
谢谢
I have problems with importing correctly a module on appengine. My app generally uses django with app-engine-patch, but this part is task queues using only the webapp framework.
I need to import django settings for the app to work properly.
My script starts with:
import os
import sys
sys.path.append('common/')
# Force Django to reload its settings.
from django.conf import settings
settings._target = None
# Must set this env var before importing any part of Django
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
I always get this error, or something related:
<type 'exceptions.ImportError'>: No module named ragendja.settings_pre
because the settings.py file starts with
from ragendja.settings_pre import *
I think I need to add ragendja to sys.path again but I had several tries that didn't work.
Here is my directory:
project/
app.yaml
setting.py
common/
appenginepatch/
ragendja/
setting_pre.py
myapp/
script.py
Is it only a sys.path problem and how do I need to modify it with the correct syntax?
Thanks

应用程序引擎补丁在内部操作 sys.path。后台任务会绕过该代码，因此您的路径将无法为 Django 调用做好准备。您有两个选择：
手动修复路径。 应用引擎文档（请参阅“处理导入路径操作”小节") 建议将路径操作代码分解到可以由任务脚本导入的模块中。
如果可能的话，消除对 django 代码的依赖。如果您可以将任务编写为纯 python 和/或 google api 调用，那么您就可以开始了。对于您的情况，这可能意味着重构您的设置代码。
App engine patch manipulates sys.path internally. Background tasks bypass that code, so your path will not be ready for Django calls. You have two choices:
Fix the paths manually. The app engine documentation (see the sub-section called "Handling import path manipulation") suggests factoring the path manipulation code into a module that can be imported by your task script.
Eliminate dependencies on django code, if possible. If you can write your task to be pure python and/or google api calls, you're good to go. In your case, this might mean refactoring your settings code.
为什么不呢：
因为 ragendja 就在这个目录中？
Why not:
since the ragendja is in this directory?
