Hi Dev,

In this quick example, let's see angular 12 to angular 13 upgrade. i would like to show you update @angular 12 to 13. it's simple example of upgrade angular cli to 13 in ubuntu. We will look at example of update angular 12 to 13. you can also upgrade angular 10 or angular 11 to angular 13 version.

When i was working on my angular application i need to update my angular 12 version to angular 13. i wan run command for update angular version but i can not do it that. it say me some configuration affected. so i thought how i can update my angular 12 to angular 13.

I have two way to upgrade your angular 12 to 13 first we will directly update your angular cli version. if it's not working for you then you can uninstall and reinstall your angular cli with bellow steps.

Let's see both way:

Way 1: Update Angular CLI:

You can directly upgrade your angular cli version globally by using update command of ng. so you can do it by bellow command.

ng update @angular/cli @angular/core

Now you can see ng version by following command:

ng version

Way 2: Update Angular CLI using reinstall:

I will show you list of commands for update version angular 12 to angular 13 by using uninstall and upgrade angular version.

Uninstall Angular CLI:

npm uninstall -g @angular/cli

Clear Cache:

npm cache clean --force
  
npm cache verify

Install Angular CLI:

npm install -g @angular/cli

Now you have new version of angular cli. so you can check it by following command:

ng version

You will see layout like as bellow:

I hope it can help you...
