google-app-engine:导入仅在刷新后才有效

标签: google-app-engine importerror python-2.5 gflags

在简单导入httplib2之后遇到一些问题(请参阅我的帖子here),我遇到了导入gflags的不同问题。

事实上,在开发服务器上,我第一次使用应用程序时出现了ImportError。但是,如果我刷新浏览器,应用程序的工作原理!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运行,但在appspot上传后它根本不起作用:

<type 'exceptions.ImportError'>: No module named gflags
Traceback (most recent call last):

我的问题:

  • 为什么zipimporter只在刷新后才能工作?
  • 如何在appspot上修复此错误?

Thans @greg。

我在__init__.py添加了import gflags,然后我使用apiclient/model.py而非from gflags import gflags修改了import gflags
