webpack配置端口号错误,options.startPort(80) is less than 1024

Question

原配置：

    host: 'localhost',
    port: 80, 
    autoOpenBrowser: true,
    errorOverlay: true,
    notifyOnErrors: true,
    ......

跑不起来，报错如下：

Error: Provided options.startPort(80) is less than 1024, which are cannot be bound.

有大佬知道原因吗？我换个8080的端口就可以了，是不能小于1024吗，为什么啊

Answer 1

端口号不能小于1024. 1024以下都是专用端口.
