Django模块已经导入和python鸡蛋警告

Question

任何人都可以帮助我在Django摆脱这些警告吗？

/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. 

我不知道如果“模块已经进口”的错误已与“不能提取PYTHON蛋”错误的事。

在我的WSGI中，我已经有了以下行os.environ['PYTHON_EGG_CACHE'] = rel('python-eggs')，并且我确实知道这是行得通的。否则，WSGI将不会加载我的应用程序。所以我不确定这里要做什么。

谢谢！

Answer 1

当您收到类似“您的帐户可能无法访问此目录的写入权限？最好做一个快速测试。尝试将其更改为“/ tmp”（可由所有人写入）并查看是否开始工作。如果解决了这个问题，您可以确定一个更合适的目录，并确保您（或服务器）具有写入权限。

更新：您在选择解决最早的错误消息时是正确的。这是一个快速实用程序，Python Module Dump，我几年前编写的，用于追踪错误包含的模块错误。您可以尝试在初始化代码路径中的有趣点处插入它，并查看是否可以在早期导入时发现。

Answer 2

您的初始问题“模块已经导入”实际上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（如上面的Peter Rowell所述）。

我今天在谷歌代码大学遇到了这个很好的小复习。不会伤害通过这个脱脂当你有一段时间了：http://code.google.com/edu/tools101/linux/ownership_permissions.html

刚才看了上面这里的评论是我的想法：

我认为问题是，.wsgi文件没有设置环境变量时间。你可以请张贴你的.wsgi文件吗？另外，你如何抓包？它是一个脚本？通过点子手动？
