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

Question

虽然运行 Cypress 在 jenkins 上进行测试，但我收到以下错误。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，这将解决问题。我如何在 docker 容器中安装 pdf-parse，哪个文件执行此操作？有人可以指点一下吗？

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

RUN useradd -r --no-log-init -u ${USER_ID} -g appuser appuser

我想你使用 cypress/base:10 作为图像在 jenkins 中新建一个容器。如果您没有 dockerfile，您可能必须编写自己的 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：您必须找到您的项目如何选择图像来启动您的容器，有了这个，您可以找到合适的安装方式 pdf-parse。下一个可能：

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' }。
