如何在jenkins docker容器中安装npm解析库？

Question

在jenkins上运行Cypress测试时，我得到了以下错误。我们的jenkins与Docker容器集成，devs要求我在码头容器中安装pdf-parse库，这将解决这个问题。如何在码头容器中安装pdf-parse，哪个文件是这样做的？能给我个建议吗？

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.

我想您应该使用cypress/base:10作为图像，在jenkins中新建一个容器。如果您没有dockerfile，您可能必须编写您自己的从cypress/base:10扩展的dockerfile。

文档：

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

然后，docker build -t mycypress .、docker push mycypress将映像推送到dockerhub(您可能需要一个帐户)，以便让jenkins使用您的新映像来设置容器。

注意:您必须找到项目如何选择映像来启动容器，这样，您就可以找到安装pdf-parse的合适方法。其中一个可能是下一个：

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' }。
