Angluar 12: I can't do ng serve --open

Issue

I don't know if this is an error but every time I do ng serve --open in my terminal I always received this message:

D:\3rdYR\AppDev\bigProject\public>ng serve --open
This version of CLI is only compatible with Angular versions ^13.0.0,
but Angular version 12.2.5 was found instead.

Please visit the link below to find instructions on how to update Angular.
https://update.angular.io/

I only use angular 12

What I've tried so far

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

npm install -g @angular/cli@12.1.0
ng --version

Just like the answer below, I tried to do npm cache clean --force but I get this from my terminal:

npm WARN using --force Recommended protections disabled.

I also tried to go to %appdata% and delete the npm-cache folder and run npm cache clean --force again, but I still get this:

npm WARN using --force Recommended protections disabled.

and when I tried to ng-serve it I still get the message (above)

Solution

Do this.

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

npm install -g @angular/cli@12.1.0
ng --version

you can also try installing other versions like 12.2 or the latest 12.* using the above command. For reference, I have mentioned 12.1.0

---

If you are getting disabled error, do this:

delete it manually: type in windows search - run - %appdata% - delete npm-cache folder Reinstall the node that should fix everything

npm install -g npm@latest

Run above command only after deleting npm-cache folder
