Build on Netlify works but fails on GitLab: GitLab Runners Issue? (Nuxtjs)

Support

1

Hello!
Total noob here.
For a while I had my site hosted both here and on GitLab pages. Using near identical scripts:

// from package.json
// .. inside "scripts"
   "generate:gitlab-pages": "DEPLOY_ENV=GITLAB_PAGES nuxt generate",
    "generate:netlify": "DEPLOY_ENV=NETLIFY nuxt generate",

The difference between the two being the configuration of the baseurl (as GitLab pages is namespaced).

Aside from that they are identical. It works on Netlify. Fails on GitLab. The error on GitLab is:

What do I do?
I don’t know enough to begin even trying to debug. I googled the python thing and StackOverflow says something about maybe NPM v16? Not sure.

One of the node packages in your project has node-gyp as a dependency, which in turn requires Python.

Error: Can't find Python executable "python", you can set the PYTHON env variable.

The build image that Netlify use has a lot of things pre-installed, which is probably why it worked there automatically.

To fix you’ll need to ensure that python is available when running on GitLab.

As you’re not having any problem with Netlify, if you continue to have GitLab specific issues, you may wish to reach out to their support.

Do you know how I do that?

I’d search Google for a solution.

A starting point though would be to check your gitlab-ci.yml and determine what build image you’re currently using.

Regardless of where you’re executing your build (locally, or remotely with any provider), you want to ensure that your build has access to all of the dependencies it requires.

image: node

before_script:
  - npm install

cache:
  paths:
    - node_modules/

pages:
  script:
    - npm run generate:gitlab-pages
  artifacts:
    paths:
      - public
  only:
    - master

no idea what version I am using

The build image is specified as that first line:

The GitLab docs provide more detail:

I believe the image is:
https://hub.docker.com/_/node

As none of this concerns Netlify and only your project and GitLab, this isn’t the right place to request assistance. You should familiarise yourself with the relevant GitLab documentation and if you’re unable to self-solve request assistance in a more GitLab centric support environment, or somewhere generic like Stack Overflow.

Thank you for all the help so far. I posted here because it was suggested that since it worked on Netlify and not GitLab that maybe someone smart would know
