Angular ng 测试模块未找到 : Error: can't resolve

Question

上周我使用命令 ng new [myProjectName] 启动了这个 Angular 项目。我使用 ng g c [componentName] 生成了组件，它使用 .spec.ts 文件正确生成了每个组件。然后，在实现业务逻辑并编写一些测试代码后，我说 ng test 尝试运行测试代码，但出现了一大堆错误。

我在命令行上遇到的所有这些错误都采用以下形式:找不到模块:错误:无法解析 [someNodeJSLibFolder] 中的 [someNodeJSDependency]。应该产生的浏览器，应该包含测试的输出，无法捕获(它启动两到三次，但空白，然后关闭)。 ng 然后说它正在放弃。

项目的package.json是这样的:

我尝试在项目根目录下说node rebuild，但这对这些错误没有任何影响。

在删除我的 node_modules 文件夹并重新安装最新版本的 node.js 之后，我遇到了同样的错误，它对我有用。
