Karma 未在 Jenkins CI 中运行，找不到模块 'Karma-jasmine'

Question

我正在Jenkins CI建立一个带自动测试的Angular 4 SPA。SPA是一个更大的、由Maven管理的项目的一部分，因此构建也是由Maven进行管理的。到目前为止，我已经：

1. 在Jenkins上安装NodeJS插件，使用安装来自版本为8.6.0的nodejs.org
2. 配置“要安装的全局npm软件包”=“karma-cli phantomjs-预构建的jasmine-core karma-jasmine karma-phantomjs-启动器karma-junit-记者karma-覆盖”
3. 在浏览器的pom.xml中添加了“maven-karma-plugin”=PhantomJS/SingleRun=true/记者=dots， junit
4. 启用”提供节点

构建过程开始时非常顺利，但最终我得到：

在生成日志的开头安装 npm：

（包“业力”目前不在列表中的原因是我在某处读到应该使用业力来代替业力。但是，添加“karma”包不会改变任何东西。

任何想法为什么“找不到模块'业力茉莉花'”弹出？在（2）中，你会看到列出了karma-jasmine软件包，我在服务器上找到了它，但仍然没有被NodeJS插件找到。

谢谢，西蒙

我通过运行“npm install”作为构建过程的一部分，然后在本地npm包上运行所有内容，设法让它正常工作。

整个设置如下所述：https://funneltravel.wordpress.com/2017/10/16/running-karma-with-maven-on-jenkins-ci/
