How do you install Firebase tools in a Gitlab CI Runner? - npm

Question

I'm having some trouble configuring Gitlab CI to run firebase emulators. In particular, it's failing to install firebase-tools. This is the relevant part of my config
unit-test-job: # This job runs in the test stage.
image: node:14.14.0
artifacts:
paths:
- "test-results.xml"
reports:
junit: "test-results.xml"
stage: test
script:
- apt-get update && apt-get install -y openjdk-8-jdk
- npm i
- npm i -g firebase-tools
- firebase use $MY_PROJECT
- echo "Running unit tests..."
- npm run test:ci
When trying to install firebase-tools I get this error from the CI
$ npm i -g firebase-tools

Any suggestions on how to fix this?

Answer 1

You're actually encountering an issue that isn't necessarily related to gitlab-ci, but it actually related to node 14. Essentially that /root/.npm folder has bad permissions in node 14. You have three ways you can fix this:
Update to Node 15 (just change your image to node:15) which fixes the permission issue
Allow node permissions to scan the folder. This is insinuated by the error message you have in the above error where it tells you the directory can't be scanned. The easiest way to resolve this issue is to remove the -g off the second node install, which will make it deploy to the user folder instead of global. Since you're rebuilding the container every time and using the same user each time, the -g to install globally is redundant in this case.
Install Firebase using the standalone method to get the CLI instead of using NPM to install it. You can do this in a docker container using curl -sL firebase.tools | sed 's/sudo //g' | bash
Hopefully this helps!
