python – dev_appserver.py给了我一个错误

在OS X Lion上将GAE升级到1.7.6后,我遇到了一个错误,当我运行dev_appserver.py时无法解决.它在以前的版本中运行良好.最初错误说我需要使用pip安装PyObjC和PIL.现在,它说无法打开文件’/usr/local/bin/_ python_runtime.py’：[Errno 2]没有这样的文件或目录.这是完整的错误：

我发现了一篇关于这个here的类似帖子,但是它出现在Windows 7机器上并没有出现他找到了解决方案(或许他确实没有跟进).有任何想法吗？

编辑：它适用于GoogleAppEngineLauncher GUI,但不适用于命令行.不知道为什么.
