【问题描述】：

我正在 Jenkins CI 中设置具有自动测试功能的 Angular 4 SPA。 SPA 是由 Maven 管理的更大项目的一部分，因此构建也是由 Maven 管理的。到目前为止，我已经：

在 Jenkins 上安装了 NodeJS 插件，使用从 nodejs.org 安装，版本为 8.6.0 已配置“要安装的全局 npm 包”=“karma-cli phantomjs-prebuilt jasmine-core karma-jasmine karma-phantomjs-launcher karma-junit-reporter karma-coverage” 在 pom.xml 中添加了“maven-karma-plugin”，browsers=PhantomJS / singleRun=true /reporters=dots,junit 在 Jenkins 作业配置中启用“将节点和 npm bin/ 文件夹提供到 PATH”

构建过程开始时很好，但最终我得到：

[INFO] --- maven-karma-plugin:1.6:start (default) @ webclient ---

构建日志最开始处的 npm install：

（“karma”包目前不在列表中的原因是我在某处读到应该使用 karma-cli 代替 karma。但是，添加“karma”包不会改变任何东西。）

知道为什么会弹出“找不到模块'karma-jasmine'”吗？在（2）中你会看到 karma-jasmine 包被列出来了，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

【参考方案1】：

我设法通过在构建过程中运行“npm install”来使其工作，然后在本地 npm 包上运行所有内容。
