无法启动devlopment服务器 - BindError:无法找到一致的端口localhost

Question

Google-app-engine开发服务器昨天运行良好,但是今天我尝试启动它.它只会喊出这个错误.

我尝试使用lsof -i:8080/ lsof -i:8000来确保不采用这些端口.我也尝试使用--port arg切换到另一个端口.我甚至删除了gae文件夹并安装了一个新文件夹. - 没有运气.

也许有一个明显的解决方案,但我看不到它.

这是Oh-My-God跟踪堆栈..

这可能是由于hosts文件中有多个"localhost"条目引起的.

例如在文件中/etc/hosts:

127.0.0.1 localhost
127.0.0.1 mymachinename localhost

如果删除所有映射但删除了localhost的映射,则希望解决问题.

127.0.0.1 mymachinename localhost

这是一个已知问题,据我所知,它将在未来版本中得到纠正.
