解决React错误：TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

运行React应用：

yarn start

报错：

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

在*上找到了解决方法，只需要把react-scripts升级到"^3.4.0"即可。

解决步骤：

1. 在package.json中，把"react-scripts": "^3.x.x" 替换为"react-scripts": "^3.4.0"
2. 删除node_modules文件夹
3. 执行npm install 或者 yarn install重新安装依赖包
