title: GitLab CI npm command not found (ubuntu image)
body: <p>I want to use node and npm in my CI, but not use the node image for that! It is because I need to be able to run python and stuff. So I want to just use an ubuntu image and install what I need in the script. Somehow it does not work with nodejs. Neither node nor npm seem to be installed.</p>
  
  <p>I have simplified my <code>.gitlab-ci.yml</code> for that:</p>
  
  <pre><code>image: ubuntu:latest
  
  stages:
      - build
  
  build:
      script:
          - apt-get update -yqq
          - apt-get install -y nodejs
          - npm -v
  </code></pre>
  
  <p>Do you see me doing anything wrong? </p>
