vue-cli设置引入目录

打开build/webpack.base.conf.js文件

找到module.exports下的resolve这行

resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src'),
    }
  },

当前@号引入 import XXXUploadWeb from '@/components/upload/upload.vue'

修改过后

resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src'),
      'src': path.resolve(__dirname, '../src'),
      'pages': path.resolve(__dirname, '../src/pages'),
      'common': path.resolve(__dirname, '../src/common'),
      'vendor': path.resolve(__dirname, '../src/vendor'),
      'components': path.resolve(__dirname, '../src/components'),
    }
  },

然后你就可以在任意.vue文件，使用import xxxComponent from 'components/xxxComponent'
