Vue执行yarn dev报错Cannot find module './utils/ast-utils'

Module build failed (from ./node_modules/@vue/cli-plugin-eslint/node_modules/eslint-loader/index.js):
Error: Cannot find module './utils/ast-utils'

解决方法：

1. 删除node_modules文件夹 和 package-lock.json文件
2. 添加eslint-loader在package.json中
3. 重新执行yarn install, yarn dev 即可

"devDependencies": {
  "eslint-loader": "2.1.2" // note this strict version, not "^2.1.2"
}
