【问题描述】：

我对 gae 很陌生，但我有一个任务必须部署在 google 上。因为sudo /usr/local/bin/dev_appserver.py之后不知道怎么停，所以直接按control+c。过了一会儿，当我再次尝试部署时，我收到以下消息：

到目前为止，我尝试重新安装 gaelauncher，但它不起作用。拜托，任何帮助都会很好。

【问题讨论】：

你可以看看stackoverflow.com/questions/15985130/…的一些答案基本上你需要找到使用端口的进程并结束它。

【解决方案1】：

几天后，它再次起作用。我认为这是 Google App Engine 的事情，到目前为止我还不知道它的原因。但如果你只是想使用 deploy-on-localhost 功能，请使用其他工具，会更容易。建议：MAMP。
