If you're facing issues adding Angular Universal with Express Engine to an Angular 14 project, and encountering errors with the command:

ng add @nguniversal/[email protected]

Solution: I encountered a similar problem, and here's how I resolved it:

1. Compatibility Check: Ensure that the versions of Angular Universal and Angular CLI are compatible with Angular 14

2. Update Angular CLI: Update your Angular CLI to the latest version using the following command:

   npm install -g @angular/cli@latest
   

3. Use Latest Angular Universal: Instead of specifying a version, try installing the latest version of Angular Universal:

   ng add @nguniversal/express-engine
   

4. Clear npm Cache: Clear the npm cache to prevent potential caching issues:

   npm cache clean --force
   

5. Retry Installation: After performing the above steps, try running the installation command again:

   ng add @nguniversal/express-engine
   

Hope this helps!
