GitLab runner only executing one command

Question

I have the following configuration in .gitlab-ci.yml:

stages:
- build

build:
  stage: build
  script:
    - npm install -g gulp
    - npm install
    - gulp

But the runner is only executing the first command (npm install -g gulp). It runs the first command and reports success, without executing the others.

The build log:

Running with gitlab-ci-multi-runner 1.6.1 (c52ad4f)
Using Shell executor...
Running on WINBUILDER...

Build succeeded

I've seen several config examples using multiple commands in a stage. I don't understand why the other commands are not running.

It's actually an NPM bug as described here:

https://github.com/npm/npm/issues/2938

NPM closes the shell upon exit and subsequent commands are not called.

A workaround is described in the issue above. Just add a call command before calling NPM:

stages:
- build

build:
  stage: build
  script:
    - call npm install -g gulp
    - call npm install
    - gulp
