NodeJS,gulp,错误:听EADDRINUSE ::: 3000

Question

我正在使用NodeJS,我正在使用gulp.

我的看起来像那样:

Root 
  dist
  node_modules
  src
    index.html
  gulpfile.js
  package.json

我的gulpfile是:

"use strict";

var gulp = require('gulp');
var connect = require('gulp-connect'); // runs a local dev server 
var open = require('gulp-open'); // open a URL in a web browser

var config ={
    port : 3000,
    devBaseUrl : 'http://localhost',
    paths:{
        html:'./src/*.html',
        dist:'./dist'
    }
}

//Start a local development server 
gulp.task = ('connect' , function(){
    connect.server({
        root:['dist'],
        port: config.port,
        base: config.devBaseUrl,
    }); 
});

gulp.task('open', ['connect'], function(){
    gulp.src('dist/index.html').pipe(open({uri: config.devBaseUrl + ":" + config.port + '/'}))
});

gulp.task('html',function(){
    gulp.src(config.paths.html)
        .pipe(gulp.dest(config.paths.dist))
        .pipe(connect.reload());
});

gulp.task('default', ['html', 'open']);

当我在cmd中键入'gulp'时,我收到此错误:

C:\Users\maor\Documents\NodeProject\2>gulp

我真的不知道问题是什么,我已经检查过并且端口:3000是免费的.你能帮助我解决问题是什么吗？

Answer 1

您是否正在运行可能使用端口3000的任何其他应用程序？

前一个节点实例可能仍在运行,即使您打算将其终止.检查您的流程,我有时会遇到此问题并且通常会使用

killall node

解决它.
