新的GitHub操作在空文件夹中运行

Question

我正在使用新的GitHub actions，以下工作流的想法是在pr打开或同步时运行，它首先应该检出并安装依赖项，然后运行几个yarn脚本。

name: PR to Master
on: 
  pull_request:
    branches:
    - master
jobs:
  # Synchronize or Opened
  synchronized_or_opened:
    name: Synchronize or Opened
    runs-on: ubuntu-latest
    steps:
    - uses: actions/bin/filter@master
      with:
        args: action 'opened|synchronize'
  # Add Labels
  add_labels:
    name: Add Labels
    runs-on: ubuntu-latest
    steps:
    - uses: actions/labeler@v2
      with:
        repo-token: ${{ secrets.GITHUB_TOKEN }}
    needs: synchronized_or_opened
  # Checkout
  checkout:
    name: Checkout
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    needs: synchronized_or_opened
  # Install Dependencies
  install_dependencies:
    name: Install Dependencies
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x]
    steps:
    - run: yarn dep:install-npm
    needs: checkout
  # Typecheck
  typecheck:
    name: Typecheck
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x]
    steps:
    - run: yarn typecheck
    needs: install_dependencies
  # Prettier
  prettier:
    name: Prettier
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x]
    steps:
    - run: yarn prettier
    needs: install_dependencies
  # ESLint
  eslint:
    name: ESlint
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x]
    steps:
    - run: yarn eslint
    needs: install_dependencies
  # Danger
  danger:
    name: Danger
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x]
    steps:
    - run: yarn danger
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    needs: install_dependencies

目前它成功进入结账阶段，但是一旦运行安装作业，我收到以下错误提示：

错误：无法在“/home/runner/work/myRepo/myRepo”中找到 package.json 文件

根据这个错误提示，似乎检出过程失败或者我所在的文件夹不正确？

如在工作流程语法文档中所述：

每个作业在由runs-on指定的虚拟环境的全新实例中运行。

从这里我所能看到的，您正在一个完全独立的作业中执行检出步骤。以这种方式执行不会以任何方式影响其他作业。它实际上应该在执行npm CLI命令的那些作业中被定义。

下面是其中一个作业的示例：

jobs:
  # (...) Other jobs
  # Install Dependencies
  install_dependencies:
    name: Install Dependencies
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10.x]
    steps:
    - uses: actions/checkout@master
    - run: yarn dep:install-npm
    needs: checkout
  # (...) Other jobs

GitHub的入门工作流模板中有一些通用的示例，请参考。
