问题描述

我试图在Google App Engine中运行Python应用程序。 UI不起作用，所以我尝试使用命令行。我试过重新启动我的电脑，我尝试用dev_appserver.py --port = 9999更改端口。但它仍然表示无法绑定localhost：8000 ：

I am trying to run a Python app in Google App Engine. The UI doesn't work so I tried using the command lines. I tried restarting my PC, I tried changing port with "dev_appserver.py --port=9999 ." but it still says Unable to bind localhost:8000:

    raise BindError('Unable to bind %s:%s' % self.bind_addr)
google.appengine.tools.devappserver2.wsgi_server.BindError: Unable to bind localhost:8000

推荐答案

应用服务器启动两台服务器;一个用于您的应用程序，另一个用于开发控制台。这是导致问题的第二台服务器;它通常会在8000端口上运行。

The app server starts two servers; one for your application, the other for the development console. It is that second server that is causing the problem here; it normally would be run on port 8000.

用 - admin_port 更改开发控制台的IP地址。 switch：

Change the ip address for the development console with the --admin_port switch:

dev_appserver.py --admin_port=9000

当然，您可能仍然希望更改主应用程序服务器的端口。

You may still want to change the port for the main application server too, of course.

另请参阅< dev_appserver.py 命令行参数文档。 code>。

Also see the command-line arguments documentation for dev_appserver.py.
