Python Google应用程序引擎-Hello World教程-分段错误

我刚刚开始使用谷歌应用程序引擎，并且刚刚开始运行教程。当我这样做时：

$ python2.5 google_appengine/dev_appserver.py helloworld/ 

上面写着“分段错误”

我正在运行Ubuntu 10.10。我在的帮助下从站点安装了Python 2.5

我之所以在命令开头使用python2.5，是因为我安装了python2.5的altinstall，所以我仍然能够使用python2.7

一切看起来都应该正常，但事实并非如此。有人知道我的问题是什么吗

我能够以交互方式运行Python 2.5。只有在运行dev_appserver.py时，才会出现seg故障。我做了更多的测试，甚至在我刚刚运行时：

$ ./google_appengine/dev_appserver.py

它给我一个seg故障。我不知道这是否有帮助，但我想可能有帮助

我使用详细的输出运行它：

Segmentation fault

我检查了详细的输出，注意到最下面的一行是

import _hashlib # dynamically loaded from /usr/local/lib/python2.5/lib-dynload/_hashlib.so

所以我又运行了几个测试，当我以交互方式运行Python 2.5并尝试导入_hashlib模块时，它成功了，没有出现错误

我也去试了试他的方法。这也不起作用。

对不起，没有代表留下评论，所以我将不得不留下这个作为回答

假设您已经验证了您的google app engine安装没有损坏，我的第一反应是python2.5安装使用了python2.7中的一些文件，导致它出错。尝试运行

strace-o“log.txt”python2.5./google\u appengine/dev\u appserver.py

。这将为您提供大量的log.txt输出，因此请尝试将其变灰以查找从2.7安装中加载的任何文件

如果这没有任何结果，请尝试在gdb下运行以获得stacktrace。这将需要安装一个带有调试符号的python解释器——可能不是您想要听到的，但这是了解发生了什么的最快方法。这里的说明：如果堆栈跟踪没有显示发生了什么，那么将其发布到python邮件列表或bug跟踪器，它们应该能够帮助您
