python - 本地开发服务器的谷歌应用引擎没有终端输出？

Question

我一直在使用 google app engine 通过 python 2.7、ubuntu 12.04 和 webapp2 框架进行网络应用程序开发。

由于某些奇怪的原因，当我在本地开发服务器上运行应用程序时，我无法再像以前那样在终端上查看我的 HTTP 响应或查看错误。我不知道它是怎么变成这样的。

另外，当使用我的终端运行新的 dev_server.py 命令时，如下所示，

ahmad@ubuntu:~/GAE$ python google_appengine/dev_appserver.py wiki

我收到一条错误消息，提示正在使用套接字。我记得当我运行一个应用程序时，我必须单击 ctrl+c 来终止它并重新运行另一个应用程序。用过...

这是在本地开发服务器上运行 diff 应用程序的确切错误，

“地址已在使用”看起来端口已被其他进程使用。
