Can't run build with github action

[Tyvain]

I try to build a github CI like this:

# This workflow will run tests using node and then publish a package to GitHub Packages when a release is created
# For more information see: https://help.github.com/actions/language-and-framework-guides/publishing-nodejs-packages

name: Node.js Package

on:
  release:
    types: [created]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v2
        with:
          node-version: 16
      - run: npm run build

But I get this error:

Error: Cannot find module 'shelljs'
