Django模塊已經導入和python雞蛋警告

Question

任何人都可以幫助我在Django擺脫這些警告嗎？

/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「模塊已經進口」的錯誤已與「不能提取PYTHON蛋」錯誤的事。

在我的WSGI中，我已經有了以下行os.environ['PYTHON_EGG_CACHE'] = rel('python-eggs')，並且我確實知道這是行得通的。否則，WSGI將不會加載我的應用程序。所以我不確定這裏要做什麼。

謝謝！

Answer 1

當您收到類似「您的帳戶可能無法訪問此目錄的寫入權限？最好做一個快速測試。嘗試將其更改爲「/ tmp」（可由所有人寫入）並查看是否開始工作。如果解決了這個問題，您可以確定一個更合適的目錄，並確保您（或服務器）具有寫入權限。

更新：您在選擇解決最早的錯誤消息時是正確的。這是一個快速實用程序，Python Module Dump，我幾年前編寫的，用於追蹤錯誤包含的模塊錯誤。您可以嘗試在初始化代碼路徑中的有趣點處插入它，並查看是否可以在早期導入時發現。

Answer 2

您的初始問題「模塊已經導入」實際上與您遇到的權限錯誤有關。您最好的選擇是修復/home/interworx/.python-eggs目錄上的權限/所有權設置（如上面的Peter Rowell所述）。

我今天在谷歌代碼大學遇到了這個很好的小複習。不會傷害通過這個脫脂當你有一段時間了：http://code.google.com/edu/tools101/linux/ownership_permissions.html

剛纔看了上面這裏的評論是我的想法：

我認爲問題是，.wsgi文件沒有設置環境變量時間。你可以請張貼你的.wsgi文件嗎？另外，你如何抓包？它是一個腳本？通過點子手動？
