找不到模塊：錯誤：無法解析“@angular/core/src/render3”：ViewChildren QueryList

Question

（角度 CLI：1.7.4）

我在組件中使用 ViewChildren。 如果我將其定義為，它工作正常

@ViewChildren(TestComponent) testComponents;

但是，當我將 testComponents 的類型指定為 QueryList 時：

@ViewChildren(TestComponent) testComponents: QueryList<TestComponent>;

它給出了錯誤：

ERROR in./src/app/components/search-component/search.component.ts Module not found: Error: Can't resolve '@angular/core/src/render3' in 'D:\Test Applications\test-application\src\app\components\search-component'

Delete node-module folder and run 'npm install' command from the root directory.This installs all dependencies listed in package.json file.If you want to install specific package,execute'npm i your package name. 讓我知道它是否不起作用？
