create-react-app results in "npm" is not recognized

Question

I have been working with react for almost 1 year. I didn't have this problem but since I re-installed my OS, I cant use commands like : 'npx create-react-app my-app' and it get this result :

'"node"' is not recognized as an internal or external command,
operable program or batch file.

I have

• installed nodejs and added it's path to environment variables.
• restarted VSCode.
• restarted the system.
• uninstalled everything including files in Roaming directory.
• changed the installation directory for nodejs and updated it's path
• cleared node cache

but nothing works.

When I type in 'node -v' or 'npm -v' i get the version back. so they are recognized in the system. and also when I use yarn, this happens :

yarn create react-app client

yarn create v1.22.5

So it first begins to install the package but then I get the same error and the package gets deleted. although I can use yarn in other commands like starting the server etc.

Thanks in advance

Try deleting node modules and package-lock.json and run command yarn create-react-app client.

If it does not work try yarn create-react-app client --legacy-peer-deps
