Answer 1

Try this:
Update Ionic to the latest version: npm install -g ionic#latest
Remove node_modules folder, then npm install to put it back all the dependencies with the new Ionic version reflected with the updated node version.

Answer 2

#dev.doc ...Highly appreciate your response...
There is change in error,I hope it past the error
npm install #angular/compiler-cli#latest
npm install #angular/cli#latest
which brings to different error now..
