【问题描述】：
节点 v8.11 NPM v5.6
每当我尝试调用 polymer serve 时，都会发生错误，提示服务器无法启动并且没有可用端口，这是错误的！大多数端口都可用。
$ polymer serve

这是一个--verbose 错误日志文本http://freetexthost.com/2sjgr45yx5
我在mac上，我通过那里的网站包安装程序安装了节点
【问题讨论】：
-
尝试使用
--verbose运行，看看是否出现任何有助于排除故障的有用日志消息。 -
@tony19 它工作了，然后又再次抛出（没有可用端口）错误，我通过附加一个链接对帖子进行了编辑保存 --verbose 输出
-
尝试
polymer serve --hostname 0.0.0.0或将0.0.0.0替换为机器上可用的IP。 -
@synk 谢谢，但很想知道为什么它在本地主机上挣扎
