应用程序无法在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升级到了1.7.7。并且因为未能在本地运行任何应用程序。这包括更新前工作的应用程序和自从我创建的应用程序。我还没有遇到任何其他引用这个特定问题'无法绑定到本地主机：0'，所以任何深入了解这个障碍的见解将不胜感激。

我将包含今天添加的新Hello World应用的日志。在OS X 10.6.8上通过ActivePython使用Python 2.7。

更新：我可以通过GAE启动器部署'Hello World'应用程序，没有任何问题。我运行了命令 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。以下是输出结果：[/ b>]

8月2日16日：我安装了最新的版本的GAE启动器[1.8.3]，现在一切正常。

解决方案

c> fuser -k 8080 / tcp ，这是一个适合我的解决方案：

  lsof -P | grep'：8080'| awk'{print $ 2}'| xargs kill -9 
  

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.

I'm including the log for a new 'Hello World' app I added today. Using Python 2.7 via ActivePython on OS X 10.6.8.

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]:

Update 2, 16 August: I installed the newest version of GAE Launcher [1.8.3] and everything now works.

解决方案

For people who got Unknown key when running fuser -k 8080/tcp, here is a solution which worked for me:

lsof -P | grep ':8080' | awk '{print $2}' | xargs kill -9
