1. npm install ok，然而启动依旧失败，显示code: 'MODULE_NOT_FOUND',

2. cnpm install 同理！

3. node.js软件选择repair ，还是老样子

4. 安装 丢失的特定包，（这里面是 @vue/cli-shared-utils )，安装失败 显示

   npm ERR! code 128
   npm ERR! command failed

5. npm update和cnpm update全部卡住，没反应。

大神救我！！！
似乎cnpm install vue/cli-shared-utils 有点用，但还是它一直在转呀！感觉清空不妙！

cnpm install vue/cli-shared-utils

方法3

1. 彻底删除node_modules文件夹（时间有点慢）
2. npm install
3. 启动 npm start

启动成功！！

 DONE  Compiled successfully in 7775ms
 
  App running at:
  - Local:   http://localhost:8081
  - Network: http://192.168.6.250:8081


     

总结：

1. npm install
2. 不行的话完全删除node_modules文件夹再进行第一步
