Ionic 4 installation of CLI
First, install the Ionic CLI with npm,
npm install -g @ionic/cli
If there was a previous installation of the Ionic CLI, it will need to be uninstalled due to a change in the package name.
npm uninstall -g ionic npm install -g @ionic/cli
The -g option means install globally. When packages are installed globally, EACCES permission errors can occur. Consider setting up npm to operate globally without elevated permissions.
