How to fix Error Failed to load typescript eslint parser in eslint-config-react-app

#eslint #createreactapp

用create-react-app创建的项目，直接执行yarn eslint .，会抛出以下错误：

Error: Failed to load parser '@typescript-eslint/parser' declared in 'package.json » eslint-config-react-app#overrides[0]': Cannot find module 'typescript'
Enter fullscreen mode Exit fullscreen mode

原因是校验根目录下所有文件，自然也包括node_modules目录的文件，里面有typescript代码，于是就用typescript parser解析，但项目创建的时候又没有创建成typescript项目，于是缺少组件，自然会报错。

解决办法就是只校验src目录就好了。

yarn eslint "src/**/*.js"
yarn eslint --ext .jsx --ext .js src/
Enter fullscreen mode Exit fullscreen mode
