作为入门书，我是 node 新手，我尝试了 npm install ws@3.3.2 --save-dev --save-exact 来自 https://github.com/ionic-team/ionic-cli/issues/2922用于解决以下问题。

 node server.js

我的 repo在这里...对于我在 Windows 上的值(value)。我应该如何解决 js.183 错误？

Answer 1

我用 localhost 替换了 IP 地址，它对我有用:

之前:

server.listen(3000, '**old ip address**');

之后:

server.listen(3000, '**localhost**');

我尝试了很多解决方案，但没有一个奏效。试试这个，我希望它会有所帮助。
