无法启动开发服务器— BindError：无法找到一致的端口localhost

Question

Google应用引擎开发服务器昨天运行良好，但是当我今天尝试启动它时。它只会喊出此错误。

我尝试使用lsof -i:8080/lsof -i:8000以确保未占用这些端口。我也尝试使用–port
arg切换到另一个端口。我什至删除了gae文件夹并安装了一个新文件夹。-根本没有运气。

也许有一个明显的解决方案，但我看不到。

这是Oh-My-God跟踪堆栈。

这可能是由您的主机文件中“ localhost”的多个条目引起的。

例如在file中/etc/hosts：

127.0.0.1 localhost
127.0.0.1 mymachinename localhost

如果删除除本地主机以外的所有映射，则有望解决该问题。

127.0.0.1 mymachinename localhost

这是一个已知问题，据我了解，它将在以后的版本中得到纠正。
