  • Solving the Angular Update Error: Conflicting peer dependency

    If you’re struggling to update your Angular version and encounter the following error when executing the command ‘npm install’:

    npm ERR! While resolving: angular-test-app@0.0.0
npm ERR! Found: @angular-devkit/build-angular@16.2.11

npm ERR! Fix the upstream dependency conflict, or retry

    Here’s a potential solution:

    Delete the ‘node_modules’ folder and the ‘package-lock.json’ file, then reinstall npm. This could resolve your issue.

    To do this, execute the following commands:

    1. Delete ‘node_modules’
    2. Delete ‘package-lock.json’
    3. Run ‘npm install’
