【问题描述】：

我正在尝试使用 Github 的 node.js 工作流程在我的存储库上进行自动化测试。但是，我遇到了困难，因为节点设置在子目录而不是存储库的根目录中。我一直在寻找一种方法来指定运行 npm 命令的目录，但没有找到任何答案。

这是工作流代码：

# This workflow will do a clean install of node dependencies, build the source code and run tests across different versions of node
# For more information see: https://help.github.com/actions/language-and-framework-guides/using-nodejs-with-github-actions

name: Node.js CI

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [12.x, 14.x, 16.x]
        # See supported Node.js release schedule at https://nodejs.org/en/about/releases/

    steps:
    - uses: actions/checkout@v2
      with: 
        path: backend_app
    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v2
      with:
        node-version: ${{ matrix.node-version }}
    - run: cd backend_app
    - run: npm ci
    - run: npm run build --if-present
    - run: npm test

这是动作运行产生的错误：

    Run npm ci
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /home/runner/work/directory_name/directory_name/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/home/runner/work/directory_name/directory_name/package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent 

npm ERR! A complete log of this run can be found in:

【解决方案2】：

请指定“工作目录”。请参考我的 .yml 文件。

工作目录：./Projects/books-store-mean/webapi

如果需要为setup-node@v2步骤指定锁文件的路径，可以在with下多加一行，如下：cache-dependency-path: ./some/path/package-lock.json
@derekbaker783 令人惊讶的是要找到这个答案是多么困难。谢谢！
