python - dev_appserver.py 给我一个错误

Question

在 OS X Lion 上将 GAE 升级到 1.7.6 后，我在运行 dev_appserver.py 时遇到无法解决的错误。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，我确实这样做了。现在，它显示 can't open file '/usr/local/bin/_python_runtime.py': [Errno 2] No such file or directory。这是完整的错误:

我发现了一篇关于此的类似帖子 here ，但它是在 Windows 7 机器上，他似乎没有找到解决方案(或者他找到了但没有跟进)。有什么想法吗？

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

根据我对 Fat Lotus 的回复，以下是对我有用的内容:

我再次更新了 GAE Launcher，它重新创建了符号链接(symbolic link)，现在它工作正常。 /usr/local/bin/_python_runtime.py 链接到的当前符号链接(symbolic link)是 /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-de‌ fault.bundle/Contents/Resources/google_appengine/_python_runtime.py
