"反应错误：EPERM：不允许操作"

Question

I am learning react and trying to create react app from command line in windows 10. But it gives an error in middle of the process. Below is the error log.

My node version is v10.8.0 and npm version is 6.2.0

I am using below command to create the app.

D:\react>create-react-app myappreact

Creating a new React app in D:\react\myappreact.

Installing packages. This might take a couple of minutes.

Answer 1

I had exactly the same problem. I simply turned off my Windows Defender Real-time protection and ran the create-react-app command again, then the problem has been solved.

Answer 2

Try deleting all text files on npm-cache logs folder. It worked for me.

C:\\Users\\ yours \\AppData\\Local\\npm-cache\\_logs
