Please note It’s a very simple process. Sometimes we need to change the version of Angular while changing any of our projects. For this we have to run some npm commands and also check the version of the note.
ng -v
npm uninstall -g @angular/cli
npm cache clean --force
Above is for checking current version after the we uninstall cli and then clear cache
Now
npm install -g @angular/cli@12.1.0
ng -v
Now you can install any version you want use.
