Can anyone help me get rid of these warnings in Django please?

/usr/lib/python2.6/site-packages/simplejson-2.1.5-py2.6-linux-x86_64.egg/simplejson/_speedups.py:3: UserWarning: Module taggit was already imported from /var/www/html/matilah/taggit/__init__.py, but /usr/lib/python2.6/site-packages/django_taggit-0.9.3-py2.6.egg is being added to sys.path

pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

 [Errno 13] Permission denied: '/home/interworx/.python-eggs'

The Python egg cache directory is currently set to:

 /home/interworx/.python-eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

I'm not sure if the "Module was already imported" error has to do with the "cannot extract PYTHON EGG" error.

In my WSGI I already have the following line os.environ['PYTHON_EGG_CACHE'] = rel('python-eggs') and I know for sure that works. Otherwise WSGI won't load my app. So I'm not sure what to do here.

Thanks!

当您收到类似“也许您的帐户没有对该目录的写入权限？”这样的消息时 最好做一个快速测试。尝试将其更改为“/tmp”（每个人都可以写），看看是否开始工作。如果这样可以解决问题，那么您可以确定一个更合适的目录并确保您（或服务器）对其具有写入权限。

更新：您选择首先解决最早的错误消息是正确的。这是我几年前编写的一个快速实用程序Python Module Dump ，用于跟踪错误包含的模块错误。您可以尝试将其插入初始化代码路径中的有趣点，看看您是否可以发现早期导入发生的时间。

您最初的问题“模块已导入”实际上可能与您遇到的权限错误有关。您最好的选择是修复 /home/interworx/.python-eggs 目录上的权限/所有权设置（如上面 Peter Rowell 所述）。

我今天在谷歌代码大学遇到了这个关于权限的很棒的小复习。当你有时间时，浏览一下不会有什么坏处：http ://code.google.com/edu/tools101/linux/ownership_permissions.html

只需阅读上面的评论，这是我的想法：

我认为问题在于 .wsgi 文件没有及时设置环境变量。你能发布你的 .wsgi 文件吗？另外，你是怎么抢包的？是脚本吗？通过 pip 手动？
