Create-react-app 没有创建应用程序并抛出错误

Question

I have just started learning react but this error is coming in my way. I have installed node.js latest version 14.6.0 and it has installed successfully. The npm is also installed with version 6.14.6 But Every time I use npm on command prompt it shows like this.

'CALL "C:\Program Files\nodejs\\node.exe" "C:\Program Files\nodejs\\node_modules\npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external command,
    operable program or batch file.

But that's not the problem, it stills work somehow I don't know. By this I have installed create-react-app . I have installed it by every single old or latest method(on their github) and it installs too and version is 3.4.1 . Now problem starts from here and I have tried every method for it to resolve. I have changed PATH (which I didn't need to because paths were perfect). Error it throws is:

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts...

events.js:291
      throw er; // Unhandled 'error' event
      ^

  ]
}

It creates the file with package.json in it only. Now I have been hitting my head for almost 4 or 5 hours but it isn't working. npm.cmd in the nodejs folder does not open. And There are many other issues with it or they are issues or not. I don't know yet but kindly help me with this. Thanks.

Try adding "%SystemRoot%\system32" to path variable in environment variables
