Npm GitHub操作在生成时崩溃

我对DevOps的世界真的很陌生，我想把我的脚趾浸在水里。这就是为什么我一直在尝试设置一个简单的GitHub操作，当我推到master时，我的站点会自动部署到Firebase，但在构建阶段出现了一些问题：

Run npm run build
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /home/runner/work/ChezMout/ChezMout/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/home/runner/work/ChezMout/ChezMout/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:
npm ERR!     /home/runner/.npm/_logs/2020-01-12T12_04_27_341Z-debug.log
##[error]Process completed with exit code 254.

这是我的基本工作流程：

name: Build and Deploy
on:
  push:
    branches:
      - master

jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - name: Install Dependencies
        run: npm install
      - name: Build 
        run: npm run build

  deploy:
    name: Deploy
    needs: build
    runs-on: ubuntu-latest
    steps:
      - name: Deploy to Firebase
        uses: w9jds/firebase-action@v1.1.0
        with:
          args: deploy
        env:
          FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}
          PROJECT_ID: chez-mout

是否有我明显做错的事情？

npm安装无法找到

包.json

文件。请确保它存在于存储库的根文件夹中。（并且受版本控制且有效）
