Question

I used the following command to create a React application using Create-React-App tool:

C:\Users\Valdo\Desktop\Test\React>npx create-react-app my-app

But I encountered an error, here is my terminal log:

Creating a new React app in C:\Users\Valdo\Desktop\Test\React\my-app.

Installing packages.
This might take a couple of minutes.

Installing react, react-dom, and react-scripts with cra-template...

Deleting generated file... package.json
Deleting my-app/ from C:\Users\Valdo\Desktop\Test\React

Answer 1

Try to npm cache clean --force first and then run your command again, this might solve your problem.

This will delete all data from the cache folder that may be responsible for your error.
