How to run jest by lerna in github actions

Question

I am trying to run jest for a monorepo project maintained by lerna in the github actions.

name: Run Unit Test

on:
  push:
    branches:
      - master
      - dev
  pull_request:
    branches:
      - master
      - dev
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2

    - name: Cache node modules
      uses: actions/cache@v2
      env:
        cache-name: cache-node-modules
      with:
        # npm cache files are stored in `~/.npm` on Linux/macOS
        path: ~/.npm
        key: ${{ runner.os }}-build-${{ env.cache-name }}-${{ hashFiles('**/package-lock.json') }}
        restore-keys: |
          ${{ runner.os }}-build-${{ env.cache-name }}-
          ${{ runner.os }}-build-
          ${{ runner.os }}-

    - name: Install Dependencies
      run: npm -v && npm install

    - name: Run Unit Test
      run: npm run test
    
    - name: Coveralls
      uses: coverallsapp/github-action@master
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }}

I got jest: not found error when run test in github actions. you can see the error logs here. But when I run npm install and npm run test in my own macOs, everything works fine.

and this is my package.json of root:

    "packages/*"

  },
  "husky": {
    "hooks": {
      "pre-commit": "npm run lint && npm run build && git add ./"
    }
  }
}

this is the package.json of sub project:

  },
  "bugs": {
    "url": "https://github.com/ObviousJs/obvious-core/issues"
  },
  "homepage": "https://github.com/ObviousJs/obvious-core#readme"
}

my github repo address is https://github.com/ObviousJs/obvious-core.

sorry for my pool english but I really need some help (orz

Answer 1

I finally solved this problem by setting useWorkspaces: false in lerna.json

the reason is that npm6.x doesn't support workspace. And the npm version of github-action runner is just v6, so the workspaces in package.json is useless, so we should set useWorkspaces in lerna.json to false
