My angular cli version is 6.0.1 and node version is 8.11.1.
How to create or add a new project of angular
I stumbled upon this scenario too.
Here is my solution to it.
Unfortunately we are at the CLI's mercy, as the best way to create a new Angular project scaffolding.
Considering ng new {app_name}
does not support a version flag.
Our aim would be to get the right CLI version installed.
The following steps helped me workaround this:
mkdir ng-5-cli && cd ng-5-cli
npm init
npm i @angular/cli@1.7.4 --save-dev
ng new
here.cd ..
For example /ng-5-cli/node_modules/.bin/ng new some-ng5-app
This should create a new application with Angular version 5.x .
You can always install other cli versions and create custom softlinks for them to use in future.
