webpack.base.conf.js

 

module: {  
    rules: [  
      {  
        test: /\.vue$/,  
        loader: 'vue-loader',  
        options: vueLoaderConfig  
      },  
      {  
        test: /\.js$/,  
        loader: 'babel-loader',  
        include: [resolve('src'), resolve('test'),resolve('/node_modules/element-ui/src'),resolve('/node_modules/element-ui/packages')]  
      },  

 

The files required for packaging are in the [email protected]@element-ui package, but the [email protected]@element-ui package is not configured in webpack.base.conf.js.

 

Solution:

Widget node_modules 
 [email protected]@element-ui
element-ui

Then re-insert the latest version of the element-ui package.

problem solved.
