Github Actions 中的“npm install”失敗

Question

我試圖創建一個在./example文件夾上運行的 github 操作。 /.example文件夾中的代碼是使用create-react-app構建的。

工作流代碼：

name: CI

on:
  push:
    branches: [ origin ]
  pull_request:
    branches: [ origin ]

jobs:
  build_test:
    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [10.x, 15.x]

    steps:
      - uses: actions/checkout@v2
      - name: Use Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v2
        with:
          node-version: ${{ matrix.node-version }}
      - name: npm install, build, and test example
        working-directory: example
        run: |
          npm install
          npm run build --if-present

但它會導致錯誤：

我的項目的結構（在./example 中有package.json ）：

您的工作流 yaml 文件應如下所示。

name: CI

on:
  push:
    branches: [ origin ]
  pull_request:
    branches: [ origin ]

jobs:
  build_test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x, 15.x]
    steps:
      - uses: actions/checkout@v2
      - name: Use Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v2
        with:
          node-version: ${{ matrix.node-version }}
      - name: npm install, build, and test example
        working-directory: ./example
        run: |
          npm install
          npm run build --if-present
