Error: Cannot find module ‘@angular/compiler-cli/linker’

  angular, dockerfile, gitlab-ci

I’m using gitlab to build a Docker image from an Angular application. This always worked fine but for some reason the build breaks since yesterday during

RUN node_modules/.bin/ng build --configuration=staging

with the following error message:

tsconfig, main.ts, package.json, Dockerfile … haven’t been changed for quite a while now so I’m clueless why this is suddenly no longer working. Any hints appreciated!
