Node JS runtime but requires python

Question

I am utilizing https://www.npmjs.com/package/youtube-dl-exec through a simple JS lambda function on an AWS lambda (node 14). The code is pretty simple and gathers info as per the URL given (and supported by YTDL). I have done testing with jest and it works well on my local where python 2.7 is installed.

My package.json dependencies look like

 "dependencies": {
    "youtube-dl": "^3.5.0",
    "youtube-dl-exec": "^1.2.0"
},
  "devDependencies": {
    "jest": "^26.6.3"
  }

I am using github action to deploy the code on push to master using main.yml file:

name: Deploy to AWS lambda
on: [push]
jobs:
  deploy_source:
    name: build and deploy lambda
    strategy:
      matrix:
        node-version: [14.x]
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Use Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v1
        with:
          node-version: ${{ matrix.node-version }}
      - name: npm install and build
        run: |
          npm ci
          npm run build --if-present
        env:
          CI: true
      - uses: actions/setup-python@v2
        with:
          python-version: '3.x' # Version range or exact version of a Python version to use, using SemVer's version range syntax
          architecture: 'x64' # optional x64 or x86. Defaults to x64 if not specified
      - name: zip
        uses: montudor/[email protected]
        with:
          args: zip -qq -r ./bundle.zip ./
      - name: default deploy
        uses: appleboy/lambda-action@master
        with:
          aws_access_key_id: ${{ secrets.AWS_EEEEE_ID }}
          aws_secret_access_key: ${{ secrets.AWS_EEEEE_KEY }}
          aws_region: us-EEEEE
          function_name: DownloadEEEEE
          zip_file: bundle.zip

I am getting a

    INFO    Error: Command failed with exit code 127: /var/task/node_modules/youtube-dl-exec/bin/youtube-dl https://www.EXQEEEE.com/p/XCCRXqXInEEZ4W4 --dump-json --no-warnings --no-call-home --no-check-certificate --prefer-free-formats --youtube-skip-dash-manifest

}

error.

I have tried adding a lambda layer, adding python in the main.yml file, and also installing through dependency but perhaps I am doing something wrong so that the library is not able to find python at /usr/bin/env.

• How do I make python be available in that path?
• Should I not use ubuntu-latest on lambda config (main.yml) since it doesn't come packed with python by default?

Any help would be appreciated.

The new nodejs10.x Lambda runtime does not contain python anymore, and therefore, youtube-dl does not work
