2022.7.7 一些错误总结

1.拉取代码后 npm i 提示错误

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

解决方案： 输入 npm i --legacy-peer-deps 回车解决（记得重启服务）

2.npm -version 报错

Error: Cannot find module 'yallist'

    'C:\\Users\\18308\\AppData\\Roaming\\npm\\node_modules\\npm\\bin\\npm-cli.js'
  ]
}

解决方案：

方法一：删除C:\Users\Administrator下的.npmrc文件即可（可能会没有，执行方法二）

方法二：删除C:\Users\Administrator\AppData\Roaming下边的npm、npm-cache

方法三：删除C:\Users\Administrator下的.npm_repl_history文件

之后重新安装node.js，即可

3.注意node版本，版本太老不行

4.执行 npm run serve 时报错：The project seems to require yarn but it‘s not installed。

解决方案：npm install -g yarn
