You probably did the installation steps correctly, but didn't install properly.

Check with ng update if you have the latest angular goods.

Check with npm outdated to see if some package is being annoying to you.

In the case you have a proxy, and it is not allowing the installation of some parts of the CLI, add the proxy to node with 

npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080

In the case the problem was with git, install git.

In the case the problem is with dependencies, be sure to update them with npm i @lacking-dependency

Also, be sure to know the difference between --save-dev and --save

As it's quite clear from the error message, @angular-devkit/build-angular is not available in the installed node_modules.

Just run this:

npm install --save-dev @angular-devkit/build-angular

And you should be good.

  • who says he dosent have it installed? maybe he just need to include it in the Angular module app? – Talg123 Jan 11 '19 at 19:25
  • @Talg123, Angular depends on `@angular-devkit/build-angular` to build the app before it could be served. It's not something that you generally add to the imports array of an `NgModule`. – SiddAjmera Jan 11 '19 at 19:28
