Answer 1

That version of Ionic doesn't exist. Try installing from the versions listed here NPM's Websites

Then npm install -g [email protected] for the latest version of ionic

Answer 2

Do you already have an existing version of Ionic?

Try updating your current version or:

sudo npm uninstall -g ionic && sudo npm install ionic

Or:

npm install -g @ionic/[email protected]

As suggested by the other user.
