问题描述
所以我想运行ng test并将测试包含在项目文件夹旁边的文件夹中。
mainproject/
|-- src/
| |-- app/
| | |-- home/
| | | |-- home.component.spec.ts
| | |-- app-main.component.spec.ts
| |-- test.ts
| |-- tsconfig.spec.json
|-- node_modules/
|-- angular.json
|-- package.json
|-- tsconfig.json
components/
|-- common/
|-- control-bar/
|-- control-bar.component.ts
|-- control-bar.component.spec.ts
当我在组件文件夹中不包含其他测试的情况下运行ng测试时，它可以按预期工作，但是当我尝试包含其他组件时，ng测试失败并显示以下错误。

因此原始加载程序似乎丢失或找不到它。要清楚的是，此设置中只有1个node_modules，它位于mainproject文件夹中。
解决方法
我遇到了完全相同的问题，我已经放弃寻找合适的解决方案。现在，我通过确保单独安装库的依赖项来使其工作（因此库中有第二个 node_modules 文件夹）。
由于在该主题上找不到任何内容，并且 official angular documentation for creating libraries 提到需要构建库：
Build the library. You cannot use a library before it is built.
我假设动态链接到没有自己的 node_modules 的未构建库是完全不受支持的（即使只要库中没有导入组件类，它就可以正常工作）。
