Template not provided using create-react-app

If you’ve previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version.

Docs

Use either one of the below commands:

• npx create-react-app my-app
• npm init react-app my-app
• yarn create react-app my-app

if npm uninstall -g create-react-app stated above does not work.
Type which create-react-app to know where it is installed. Mine was installed in /usr/bin folder. Then do sudo rm -rf /usr/bin/create-react-app. (Credit to @v42 comment below)
