npm start 抛出与精简版服务器相关的未知错误

Question

我 3-4 周前在 Angular2 工作，并在云上保持项目原样。现在的问题是项目不会运行，在启动时抛出此错误。

我认为问题出在 lite-server 上，但我确实更新了节点模块和 npm。这是我的代码还是 npm 的问题？

Answer 1

问题出在 lite-server 设置的端口上。

几周前，我是运行默认精简服务器端口 3000 上的应用程序。但我将其更改为 http 端口 80。我忘记了。

现在我所要做的就是sudo npm start

npm start 抛出与精简版服务器相关的未知错误

npm start is throwing unknown error related to lite server

node.js

npm

lite-server
