1、修改package.json 相关模块版本，然后删除node_modules文件夹，运行如下命令：
cnpm install
cnpm list
vue项目常用依赖如下

2、显示添加 vueLoaderConfig 插件
修改 webpack.base.conf.js 文件
// ...(config.dev.useEslint ? [createLintingRule()] : []), 注释掉
const vueLoaderConfig = require('./vue-loader.conf')
// 添加代码
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
}),
new VueLoaderPlugin(),
],
3、ExtractTextPlugin 插件改为使用 MiniCssExtractPlugin插件
utils.js 文件
// Extract CSS when that option is specified
// (which is the case during production build)
if (options.extract) {
// return ExtractTextPlugin.extract({
// use: loaders,
// fallback: 'vue-style-loader'
// })
return [ MiniCssExtractPlugin.loader ].concat(loaders)
} else {
return ['vue-style-loader'].concat(loaders)
}
webpack.prod.conf.js 文件
// extract css into its own file
new MiniCssExtractPlugin({
filename: utils.assetsPath('css/[name].[contenthash].css'),
// Setting the following option to `false` will not extract CSS from codesplit chunks.
// Their CSS will instead be inserted dynamically with style-loader when the codesplit chunk has been loaded by webpack.
// It's currently set to `true` because we are seeing that sourcemaps are included in the codesplit bundle as well when it's `false`,
// increasing file size: https://github.com/vuejs-templates/webpack/issues/1110
chunkFilename: "[id].[contenthash].css",
allChunks: true,
})
4、webpack.optimize.CommonsChunkPlugin 插件改为使用 webpack.optimize.SplitChunksPlugin
webpack.prod.conf.js 文件
// split vendor js into its own file
new webpack.optimize.SplitChunksPlugin ({
name: 'vendor',
minChunks (module) {
// any required modules inside node_modules are extracted to vendor
return (
module.resource &&
/\.js$/.test(module.resource) &&
module.resource.indexOf(
path.join(__dirname, '../node_modules')
) === 0
)
}
}),
// extract webpack runtime and module manifest to its own file in order to
// prevent vendor hash from being updated whenever app bundle is updated
new webpack.optimize.SplitChunksPlugin ({
name: 'manifest',
minChunks: Infinity
}),
// This instance extracts shared chunks from code splitted chunks and bundles them
// in a separate chunk, similar to the vendor chunk
// see: https://webpack.js.org/plugins/commons-chunk-plugin/#extra-async-commons-chunk
new webpack.optimize.SplitChunksPlugin({
name: 'app',
async: 'vendor-async',
children: true,
minChunks: 3
}),
