Can't Make React-App

Hello, can someone help me understand why the react app will not run?
This is the result of the command I was instructed to run in terminal:

npx create-react-app myreactapp…

npm ERR! code EEXIST

npm ERR! syscall mkdir

npm ERR! path /Users/alex/.npm/_cacache/content-v2/sha512/95/3e

npm ERR! errno EEXIST

npm ERR! Invalid response body while trying to fetch https://registry.npmjs.org/html-webpack-plugin: EACCES: permission denied, mkdir ‘/Users/alex/.npm/_cacache/content-v2/sha512/95/3e’

npm ERR! File exists: /Users/alex/.npm/_cacache/content-v2/sha512/95/3e

npm ERR! Remove the existing file and try again, or run npm

npm ERR! with --force to overwrite files recklessly.

npm ERR! A complete log of this run can be found in: /Users/alex/.npm/_logs/2023-12-21T16_32_38_633Z-debug-0.log

Aborting installation.

npm install --no-audit --save --save-exact --loglevel error react react-dom react-scripts cra-template has failed.

Deleting generated file… package.json

Deleting myreactapp/ from /Users/alex

Done.

#SOLVED

I had to uninstall create-react-app globally first. Also crucial was including --use-npm when making the boilerplate.
