使用vue-cli创建vue项目，加入一些之前的代码，然后打包运行报错：
(node:4892) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing insi
de of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection
id: 1)
(node:4892) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections
that are not handled will terminate the Node.js process with a non-zero exit code.
// 然后加卡在这里不动了

网上查阅了很多的资料，下面是我整理的解决方案：
- 在build文件夹下找到webpack.base.conf.js
然后修改加入const vueLoaderPlugin = require(‘vue-loader/lib/plugin’)
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
//加入的
const vueLoaderPlugin = require('vue-loader/lib/plugin')
- 在module.exports中引入 plugins:[new vueLoaderPlugin()]
plugins:[
new vueLoaderPlugin()
]
- 下面是我的文件的完整代码
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
const vueLoaderPlugin = require('vue-loader/lib/plugin')
function resolve (dir) {
return path.join(__dirname, '..', dir)
}
module.exports = {
context: path.resolve(__dirname, '../'),
entry: {
app: './src/main.js'
},
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath
},resolve: {

alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
}
},
module: {

options: vueLoaderConfig
},
{ test: /\.js$/,

},
{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,

},
node: {
// prevent webpack from injecting useless setImmediate polyfill because Vue
// source contains it (although only uses it if it's native).
setImmediate: false,
// prevent webpack from injecting mocks to Node native modules
// that does not make sense for the client
dgram: 'empty',
fs: 'empty',
net: 'empty',
tls: 'empty',
child_process: 'empty'
},
plugins:[
new vueLoaderPlugin()
]
}
当以上解决之后再运行项目一般来说已经可以了，但是我这个项目还不行，继续其他错误
$ webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

这种错误其实网上有很多解决方法
主要的就是将对应的版本更新一下，就是对应的vue-loader这个插件的lib下面没有对应的plugin文件，具体做法：
升级了一下 “vue-loader”: “^15.7.0” 就好了
真棒！！
