应用程序不会在 GAE 上运行 - “无法绑定到 localhost:0" [英] Apps won't run on GAE - 'unable to bind to localhost:0'

问题描述

我最近将 Google App Engine 升级到 1.7.7.从那以后就无法在本地运行任何应用程序.这包括在更新之前运行的应用程序和我之后创建的应用程序.我还没有遇到过对无法绑定到 localhost:0"这一特定问题的任何其他参考，因此非常感谢您对清除这一障碍的任何见解.

I recently upgraded Google App Engine to 1.7.7. and have not been able to run any apps locally since. This includes apps that worked before the update and apps I've created since. I haven't come across any other references to this specific problem 'Unable to bind to localhost:0,' so any insights into clearing this hurdle would be much appreciated.

我包含了我今天添加的新Hello World"应用的日志.在 OS X 10.6.8 上通过 ActivePython 使用 Python 2.7.

更新:我能够通过 GAE Launcher 部署Hello World"应用程序，没有任何问题.我运行命令 errinfo -c -n GoogleAppEngineLauncher.app，它使用包含的 dtrace，然后尝试运行三个应用程序，然后关闭它们.这是输出[有点超出我的范围]:

Update: I was able to deploy the 'Hello World' app through GAE Launcher without any issues. I ran the command errinfo -c -n GoogleAppEngineLauncher.app, which uses the included dtrace, and then attempted to run three apps, then closed them. Here is the output [which is somewhat beyond me]:
