npm run build报错Unexpected token: name...

ERROR in static/js/vendor.86e2c6288e81323e1512.js from UglifyJs
Unexpected token: name (MockStorage) [./node_modules/vuex-persist/dist/esm/index
.js:6,0][static/js/vendor.86e2c6288e81323e1512.js:23043,4]

原因：Uglifyjs压缩js的的时候，要求不能有es6语法
解决方法：

vue-cli默认是检测src和test目录下的js文件。找到build/webpack.base. config.js文件做出修改
test: /.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test'), resolve('./node_modules/vuex-persist')]
