django 模块已经导入和 python Egg 警告

Question

任何人都可以帮我摆脱 Django 中的这些警告吗？

/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.

我不确定“模块已导入”错误是否与“无法提取 PYTHON EGG”错误有关。

在我的 WSGI 中，我已经有以下行 os.environ['PYTHON_EGG_CACHE'] = rel('python-eggs') 并且我确信它是有效的。否则 WSGI 将不会加载我的应用程序。所以我不知道在这里做什么。

谢谢！

Answer 1

当您收到类似“也许您的帐户没有对此目录的写入权限？”之类的消息时最好做一个快速测试。尝试将其更改为“/tmp”（每个人都可写）并查看是否开始工作。如果问题解决了，您就可以确定一个更合适的目录，并确保您（或服务器）对其具有写访问权限。

更新：您选择首先解决最早的错误消息是正确的。这是一个快速实用程序，Python 模块转储，我几年前编写的，用于追踪错误包含的模块错误。您可以尝试将其插入初始化代码路径中有趣的位置，看看是否可以发现早期导入发生的时间。

Answer 2

您最初的问题“模块已导入”实际上有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 Google 代码大学看到了关于权限的这个很棒的小复习。当您有时间时浏览一下此内容不会有什么坏处：http://code .google.com/edu/tools101/linux/ownership_permissions.html

刚刚阅读上面的评论是我的想法：

我认为问题在于 .wsgi 文件没有及时设置环境变量。您可以发布您的 .wsgi 文件吗？还有，你是怎么抢包裹的？它是一个脚本吗？通过 pip 手动？
