Lerna on AWS CodeBuild & CodeDeploy Not Installing Local Dependencies

Question

So I have a Typescript project called backend with a depedency like such in its package.json:

"dependencies": {
  "@the-couple-game/helpers": "^1.0.0",
}

And helpers (also Typescript) is in another folder with its package.json like such:

{
    "name": "@the-couple-game/helpers",
}

So running lerna bootstrap should link the two and install @the-couple-game/helpers in backend's node_modules which it does locally.

However, doing the same (with --no-ci because I don't want npm ci) using Codebuild using the below buildspec.yml does not add a @the-couple-game/helpers in backend's node_modules. So if I run backend's transpiled index.js it would complain about the missing module.

version: 0.1
phases:
  install:
    commands:
      - npm install -g lerna
  pre_build:
    commands:
      - lerna bootstrap --no-ci --concurrency 4
  build:
    commands:
      - lerna run build --concurrency 4
artifacts:
  files:
    - "**/*"

For now, I have to resort to manually doing a lerna bootstrap after deployment to CodeDeploy (using a script called from appspec.yml) so it installs the missing module but shouldn't Codebuild have covered that part?

Thanks.

So it turns out AWS CodePipeline doesn't support symlinks in source (Codebuild in my case). Reference

So after deployment, I'll have to lerna link using a shell script to create the links which is not an expensive job for my micro ec2 instance to do.
