I upgraded to Ionic 3.6.0 like described in the Changelog, respectively
npm install -g ionic@latest npm install @ionic/app-scripts@latest --save-dev npm install ionic-angular@latest --save
Afterwards, I started the command
ionic server and following question poped up
[WARN] No local CLI detected. Starting with CLI 3.6, the CLI must be installed locally to use local CLI plugins. ? Install now?
If I answer yes, following command is then run
npm install --save-dev --save-exact ionic@latest
But why? Do I then now need Ionic generally (-g) installed and one local copy of Ionic in each project I have? Really is that mandatory? Where is that documented?
P.S.: If I answer no to the question, I am not be able to start my server
ionic serve anymore. Each time the question pop up, answer no => the process stop
