Why do I get a 'Catalyst command not found' error in the CLI?

You might encounter this error if Catalyst CLI is not properly installed in your local system. You can try the following steps to rectify this error:

1. You will need to check if you installed the latest stable Node version, and if it is greater than v14, by executing the node -v command in your terminal.

2. You must also check if the NPM version is greater than v12 by executing the npm -v command in your terminal.

3. Uninstall and reinstall Catalyst CLI with the sudo command in MacOS or in the Windows command prompt in the administrator mode.
