Question

我今天尝试运行我的一个AppEnigne项目（python），但它将不再启动，这是我得到的堆栈跟踪。

 *** Running dev_appserver with the following flags:
    --admin_console_server= --port=8080 --clear_datastore
Python command: /usr/bin/python2.5
Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/dev_appserver.py", line 77, in <module>
    run_file(__file__, globals())
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/dev_appserver.py", line 73, in run_file
    execfile(script_path, globals_)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver_main.py", line 138, in <module>
    import logging
ImportError: No module named logging

我认为这可能是一个python 2.6错误，但我将路径调整为/usr/bin/python2.5并且仍然无效。我正在运行OSX 10.6.8并拥有最新的AppEngineLauncher 1.5.4

我最近改变的唯一可能影响到这一点的是当我将我的XCode更新到最新版本时，v4.2 build 4C199

最近有其他人遇到过这个问题吗？

EDIT 我也不能从终端import logging，同样的消息。这是Python的路径。

感谢尼克和沃布尔，我已经明白了。我最近将我的XCode安装更新到4.2 GM版本并删除了测试版。一路上OSX忘记了gcc的安装位置，并阻止它编译像logging这样的python模块。这导致.pyo内的/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python25/logging个文件丢失，导致import logging无效。

记录不是唯一未编译的模块，只是AppEngine尝试导入的第一个模块。

解决方案：卸载并彻底安装XCode。确保在你的PATH上找到gcc，一切都应该没问题。

本地Appengine停止工作
