How to run jest by lerna in github actions - jestjs

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:

Answer 1

I have zero knowledge about this, but for a temporary answer, what worked for me (when I had the same error with jest) was adding,
- run: lerna bootstrap --no-ci
before running my npm test command in my workflow config. Thus I ended up with a workflow like this:
on:
pull_request:
branches: [ master ]
jobs:
test_pull_request:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- uses: actions/setup-node#v1
with:
node-version: 12
# fix issue with lerna and clean installs
- run: lerna bootstrap --no-ci
- run: npm test

Answer 2

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
