How to downgrade to Angular 7 from Angular 8 or 9

Question

So I was trying to upgrade our entire web-application earlier from Angular 6 to 7. And I was able to do that since the script I run earlier installed the most latest version available of Angular which is Angular 8 (should have been 7 though as I thought) release 2 days ago. But it turns out there are build issues in the node modules when I did the upgrade to Angular 8. So instead, I want to downgrade my project from Angular 8 to Angular 7. How do I do that?. TIA.

PS: I did not expect that there is Angular 8 alright, so I thought it would install Angular 7 as the latest version.

Answer 1

Try like this :

ng --version
npm uninstall -g @angular/cli
npm cache clean --force

npm install -g @angular/[email protected]
ng --version

Update

The version 7.2.12 is given the following error :

npm ERR! code ETARGET npm ERR! notarget No matching version found for @angular/[email protected] npm ERR! notarget In most cases you or one of your dependencies are requesting npm ERR! notarget a package version that doesn't exist.

use this instead :

npm install -g @angular/[email protected]

Answer 2

you can specify the version while install,

npm install -g @angular/[email protected]

if you dont specify it will install latest version , incase specified will install given version.

here is the doc, list of angular version and its command..
