Being the latest version of Angular, Angular 8 can be upgraded from an older version of Angular. To update the Angular’s version to Angular 8, from an older version, use the below steps:
Step 1: Check the current version of Angular CLI.
Command: ng –version
Here, we are using Angular 7, and we need to update it to Angular 8.
Step 2: Uninstall the older version of Angular.
Command (For Windows Open Powershell in Administrator Mode):
npm uninstall -g angular-cli
Command (For Mac):
sudo npm uninstall -g angular-cli
Step 3: Verify and clear the cache.
Command 1: npm cache verify
Command 2: npm cache clean
Step 4: Install the latest Angular CLI, i.e, Angular 8.
Command: npm install -g @angular/cli@latest
Step 5: Verify that the Angular 8 CLI is now installed in the system.
Command: ng –version
Angular 8 is thus installed in the system.
Update Angular Packages:
For the projects that are created in the older version of the Angular, we need to go inside that folder to update that package.
Command: ng update @angular/core
The cache should be cleared, after updating both the local and global packages to avoid any error.
