vue 本地的项目别人怎么通过你本地 ip地址来访问项目

解决方法：

1.需要将build文件下的webpack.dev.conf.js里面的const devWebpackConfig上面的

const HOST = process.env.HOST
改为
const HOST = process.env.HOST || '0.0.0.0'

2.然后

const devWebpackConfig = merge(baseWebpackConfig, {
  devServer: {host:  HOST ||  config.dev.host  }    
})

3.另外devWebpackConfig.plugins.push的messages: 由

http://${config.dev.host}:${port}

要改为
http://${devWebpackConfig.devServer.host}:${port}

devWebpackConfig.plugins.push(new FriendlyErrorsPlugin({
        compilationSuccessInfo: {
          messages: [`Your application is running here: http://${devWebpackConfig.devServer.host}:${port}`],
        },
        onErrors: config.dev.notifyOnErrors
          ? utils.createNotifierCallback()
          : undefined
      }));
