我们如何在 jenkins docker 容器中安装 npm pdf-parse 库

如何解决我们如何在 jenkins docker 容器中安装 npm pdf-parse 库

在 jenkins 上运行 Cypress 测试时，出现以下错误。我们的 jenkins 与 Docker 容器集成，开发人员要求我在 docker 容器中安装 pdf-parse 库以解决问题。如何在 docker 容器中安装 pdf-parse，哪个文件可以安装？有人可以建议吗？

注意：我无法在我的项目根目录中看到 docker 文件

11:38:29  Or you might have renamed the extension of your `pluginsFile`. If that's the case,restart the test runner.

11:38:29  Please fix this,or set `pluginsFile` to `false` if a plugins file is not necessary for your project.

解决方法

我想您使用 cypress/base:10 作为图像在 jenkins 中新建一个容器。如果您没有 dockerfile，则可能需要编写自己的 dockerfile extends from cypress/base:10。

Dockerfile：

FROM cypress/base:10
RUN npm install pdf-parse

然后，docker build -t mycypress .,docker push mycypress 将镜像推送到 dockerhub（您可能需要一个帐户）让您的 jenkins 使用您的新镜像来设置容器。

注意：你必须找到你的项目如何选择镜像来启动你的容器，通过这个，你可以找到合适的方式来安装 pdf-parse。下一个可能是：

pipeline {
    agent {
        docker { image 'cypress/base:10' }
    }
    stages {
        stage('Test') {
            steps {
                sh 'node --version'
            }
        }
    }
}

然后，您可以将 docker { image 'cypress/base:10' } 更改为 docker { image 'mycypress' }。
