webpack.dll.config.js代码如下：

const path = require('path');
const webpack = require('webpack');
module.exports = {
entry: {

  vendor: ['vue-router','vuex','iview','axios','vue']

},
output: {

path: path.resolve(base.path),
filename: '[name].dll.js',
library: '[name]_library'

},
plugins: [

new webpack.DllPlugin({
  path: path.resolve('../dist', '[name]-manifest.json'),
  name: '[name]_library'
})

]
};

在webpack.prod.config.js中添加代码:

plugins: [

new webpack.DllReferencePlugin({
  manifest: require('../dist/vendor-manifest.json')
})

]

package.json文件中添加：
"scripts": {

"build:dll": "webpack --config build/webpack.dll.config.js"

},

基于vue-cli，代码如上所示，npm run build:dll 能正常把依赖单独打包出来，关键是npm run build打包还是会把这些依赖打包进去，感觉没生效？哪里有问题吗？
