使用 NodeJS 插件在 Jenkins 管道中设置 Node.js 时出错

Question

我正在学习 Jenkins，并致力于建立一个基本管道，通过一个简单的 React 项目来练习 CI/CD。该管道旨在：

从 GitHub 拉取最新提交。 使用 Jenkins NodeJS 插件安装 Node.js。 在 Docker Hub 上构建并发布项目。 但是，我在安装 Node.js 阶段遇到了问题。该错误似乎表明必须使用主体调用nodejs步骤，但我不确定这意味着什么或如何修复它。

代码：

node {
    stage('Checkout') {
        checkout([$class: 'GitSCM', branches: [[name: '*/main']],
            userRemoteConfigs: [[url: 'my_repo_credentials']],
            extensions: [[$class: 'UserIdentity', name: 'DSL User', email: '[email protected]']]
        ])
    }

    properties([
        pipelineTriggers([[$class: 'SCMTrigger', scmpoll_spec: 'H/5 * * * *']])
    ])

    stage('Setup Node.js') {
        echo "Starting Node.js Setup"
        nodejs('nodejs') 
        echo "Node.js Setup Complete"
    }

    stage('Docker Build and Publish') {
        script {
            docker.withRegistry('https://registry.hub.docker.com', 'dockerhub') {
                def image = docker.build("my_docker_container_repo:latest")
                image.push("latest") 
            }
        }
    }
}

**错误输出：**

Answer 1

在 Node.js 设置步骤中，缺少配置 Node.js 的说明。

您的原始代码：

stage('Setup Node.js') {
    echo "Starting Node.js Setup"
    nodejs('nodejs') 
    echo "Node.js Setup Complete"
}

要解决此问题，您可以在 Nodejs 步骤中添加一个块，如下所示：

stage('Setup Node.js') {
    echo "Starting Node.js Setup"
    nodejs('nodejs') {
        // Commands to execute in the Node.js environment
        sh 'npm install'
    }
    echo "Node.js Setup Complete"
}
