在简单导入 httplib2 出现一些问题后(请参阅我的帖子),我在导入 gflags 时遇到了另一个问题。
事实上,在开发服务器上,我第一次启动应用程序时遇到了 ImportError。但是,如果我刷新浏览器,这些应用程序就会工作!如果我查看日志,我可以看到:
...
ImportError: No module named gflags
[App Instance] [0] [dev_appserver.py:2891] INFO "GET / HTTP/1.1" 500 -
[App Instance] [0] [py_zipimport.py:148] INFO zipimporter('/usr/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '')
[App Instance] [0] [py_zipimport.py:148] INFO zipimporter('/usr/lib/python2.5/site-packages/python_gflags-2.0-py2.5.egg', '')
因此,应用程序在开发服务器上刷新后可以工作,但在 apppot 上载后它根本不工作:
<type 'exceptions.ImportError'>: No module named gflags

我的应用程序是这个HelloWorld:

我的问题:
- 为什么 zipimporter 仅在刷新后才有效?
- 如何在 apppot 上修复此错误?
