视图 |怎么把web的端口号改成80？

Question

所以我正在尝试部署我的 vue 应用程序，为了进行测试，我想切换端口 80，这样我就可以看到没有 :8080 扩展名的链接。当我这样做时，我得到一个致命错误

      ^

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我不确定我做错了什么我更改了配置文件中的端口，但我明白了。这也只发生在端口 80 上。

你必须做

sudo node build/dev-server.js

或

sudo setcap 'cap_net_bind_service=+ep' /path/to/nodejs

然后你就可以不用 sudo
