Angular local environment blocker.

Hello, can anyone assist with an Angular local development issue I'm experiencing? I have a project which I cloned via git. Then I ran the following in the project root directory: npm install

Here are my results: npm ERR! code E404 npm ERR! 404 Not Found - GET http://registry.npmjs.org/@easydevops%2fangular-auth-plugin - Not found npm ERR! 404 npm ERR! 404 '@easydevops/angular-auth-plugin@^1.0.2' is not in the npm registry. npm ERR! 404 You should bug the author to publish it (or use the name yourself!) npm ERR! 404 npm ERR! 404 Note that you can also install from a npm ERR! 404 tarball, folder, http url, or git url.

Any ideas on how to correct this error? Here are some commands I've tried in my project root directory: npm install angular-auth-plugin npm install @easydevops/angular-auth-plugin@^1.0.2 npm config set registry http://registry.npmjs.org

I can't find any helpful info via Google search for angular-auth-plugin.

I also received the following error when I run: npm start

An unhandled exception occurred: Cannot find module '@angular-devkit/build-angular/package.json' Require stack:

Commands I've tried to resolve the npm start error: npm install --save-dev @angular-devkit/build-angular npm audit fix npm install @angular/cli

The second error seems to be generated because of the "angular-auth-plugin" error.

When I run "ng update" I receive the following errors:

I'm using the following versions: node v15.8.0 npm 7.7.6 Angular CLI: 11.2.6

Any help would be greatly appreciated.
