I got this strange message when running:

$ npx create-react-app my-app
    
Need to install the following packages:

You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0).

We no longer support global installation of Create React App.

Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app

The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/

System:

• OS: Manjaro Linux x86_64 - 5.15.12-1-MANJARO
• CPU: AMD Ryzen 7 5800H with Radeon Graphics (16) @ 3.200GHz

Binaries:

• Node: 16.13.1
• npm: 8.3.0

I get this error as well.

• Mac V12.1
• Node version 14.x 16.x, and 17.x
• npm cache clean --force
• sudo npm uninstall -g create-react-app
• npx clear-npx-cache

Nothing seems to work.

My work around, add the version.

npx create-react-app@5.0.0 app-name

EDIT
Using a versioned create-react-app only works on 14.x, not 17.x
