詹金斯构建说成功但没有看到输出？

Question

我正在部署我的 reactjs 应用程序。为此，我编写了管道脚本以从 Jenkins 部署到 EC2 服务器上。

每次构建成功但没有输出。我找不到错误。 当我通过 putty 登录到 EC2 实例并且当我手动部署应用程序时，应用程序正在运行，但是当我在管道中编写并执行时相同的步骤，然后输出不会出现

我已经检查了几种方法但没有用

这是我在直接部署到服务器时使用的简单 Jenkins 文件，因为我正在检查错误

pipeline {
    agent {
        label 'master'
    }
    stages {
        stage('Deploy') { 
            agent {
                label 'testnode'
            }
            steps {
               script{
                    
                    sh """
                        #!/bin/bash
                        ls
                        sudo npm start &
                    """
                    
                }
            }
        }
    }
}

控制台输出

当我通过登录到 EC2 服务器手动使用相同的命令（sudo npm run start）部署应用程序时，它正在运行并且我看到了输出，但是来自 Jenkins 我遇到了这个问题。

谁能帮忙解决这个问题？

在 jenkins 管道中，始终使用“run”执行 npm 命令

ex - npm run start / npm run test / npm run lint
