我正在运行一个Github动作工作流。下面是代码：

name: Deploy to EC2

on:
  workflow_dispatch:  # Manual trigger

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Transfer code to EC2
        uses: appleboy/scp-action@master
        with:
          host: ${{ secrets.EC2_HOST }}  
          username: ${{ secrets.EC2_USERNAME }}  
          key: ${{ secrets.EC2_SSH_KEY }}  
          source: .  # Copy all files from the repository root
          target: /home/ubuntu/app/next/  
      
      - name: SSH into EC2 and Run Script
        uses: appleboy/ssh-action@master
        with:
          host: ${{ secrets.EC2_HOST }}  
          username: ${{ secrets.EC2_USERNAME }}  
          key: ${{ secrets.EC2_SSH_KEY }}  
          script: |
            cd /home/ubuntu/app
            cd next
            npm ci 
            npm run build
            pm2 restart 0

当我运行工作流时，它抛出了这个错误：

======CMD======
cd /home/***/app
cd next
npm ci 
npm run build
pm2 restart 0

======END======
err: bash: line 3: npm: command not found
err: bash: line 4: npm: command not found
2023/06/13 03:31:13 Process exited with status 127
err: bash: line 5: pm2: command not found

我在我的ec2示例上全局配置了npm和pm2。但它每次都抛出这个错误。我试过不同的方法，但不起作用
