[ERR_INVALID_ARG_TYPE]: The “path“ argument must be of type string. Received undefined报错

启动react项目报错如下:

[ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined
    at validateString (internal/validators.js:120:11)......

造成这种报错可能有两种原因,解决方案如下:

一. 可能是react-scripts版本太低了,解决如下:

   1. 在package.json中,把"react-scripts": "^3.3.0" 替换为
   "react-scripts": "^3.4.0"
   2. 删除node_modules文件夹
   3. 执行cnpm i一下

二. 修改config/webpackDevServer.config.js文件,解决如下:

看看config/webpackDevServer.config.js文件中的是不是有如下代码:

       app.use(noopServiceWorkerMiddleware());

修改成

app.use(noopServiceWorkerMiddleware('/'));

做个笔记!
