我有一个 NX 工作区，里面有 Angular 和 NestJS。我也有一些共享库。我想测试一个使用生成的共享库之一的 NestJS API 项目
nx g @nrwl/nest:lib shared/backend
我只是在我的 NestJS 项目中使用它，就像对 NX 分配的名称进行正常导入一样。当我在开发模式下运行项目本身时效果很好，但是当我使用 @nestjs/testing 模块运行应用程序时，它会失败。
Error: Cannot find module '@proj/shared/backend'

从我的 API 代码中删除库引用时，我的测试运行良好，所以它实际上只在黄瓜测试中。这是我创建测试模块的方式：
const moduleFixture: TestingModule = await Test.createTestingModule({
imports: [AppModule],
}).compile();
this.context.app = moduleFixture
.createNestApplication()
.useGlobalPipes(new ValidationPipe());
await this.context.app.init();
要启动 e2e 测试，我调用以下命令：
cucumber-js -p proj-api
我的 tsconfig.json 看起来像这样：
{
"compileOnSave": false,
"compilerOptions": {
"rootDir": ".",
"sourceMap": true,
"declaration": false,
"moduleResolution": "node",
"emitDecoratorMetadata": true,

],
"@proj/shared/feature": [
"libs/shared/feature/src/index.ts"
]
}
},
"exclude": ["node_modules", "tmp"]
}
我在根目录下的 cucumber.js
module.exports = {
'proj-api': [
'apps/proj-api-e2e/features/**/*.feature', // Specify our feature files
'--require-module ts-node/register', // Load TypeScript module
'--require apps/proj-api-e2e/step-definitions/**/*.ts', // Load step definitions
'--format progress-bar', // Load custom formatter
'--publish-quiet',
'--parallel 0',
'--exit',
].join(' '),
};
这是我在 package.json 中的依赖项

看起来 cucumber-js 不使用定义库的 tsconfig ，因为当我正常运行代码时它可以工作，而当我删除 lib 导入时，我的测试也可以工作。
有人知道吗？
