Github actions failing to install dependencies

[oliveris]

Using nvm I downgraded my node version to 10 then ran yarn and it installed successfully.

To make this work on Github actions I had to add the following to the deploy.yml.

      - name: Use Node.js
        uses: actions/setup-node@v1
        with:
          node-version: '10.x'

This adds an extra step to use this particular version of Node.

The below shows the fully updated deploy.yml file.

name: Deploy

on: [workflow_dispatch]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Git Checkout
        uses: actions/checkout@v2
          
      - name: Use Node.js
        uses: actions/setup-node@v1
        with:
          node-version: '10.x'

      - name: Yarn Cache
        uses: c-hive/gha-yarn-cache@v1

      - name: Install dependencies
        run: yarn

      - name: Build React App
        run: yarn build
        env:
          HTTPS: "true"

          PUBLIC_URL: ${{ secrets.PUBLIC_URL }}
