将“ changeDetectionStrategy”添加到我的应用程序时出错

Question

我正在用前端的Angular7构建我的第一个CRUD，Spring / hib。当我尝试在我的component.ts中添加changeDetectionStrategy时，出现以下警告：

WARNING in ./node_modules/@angular/compiler/src/core.js
10:24-31 Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

WARNING in ./node_modules/@angular/compiler/src/selector.js
10:24-31 Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

WARNING in ./node_modules/@angular/compiler/src/ml_parser/html_tags.js
10:24-31 Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

WARNING in ./node_modules/@angular/compiler/src/ml_parser/tags.js
10:24-31 Critical dependency: require function is used in a way in which dependencies cannot be statically extracted.

该应用程序具有可以正常运行的其他组件，并且具有changeDetectionStrategy导入。当我将方法添加到我的组件中时，角度会给我这些错误。我注释了所有组件，除了@Component东西和“导出类XY {}”。错误一直存在，直到我删除changeDetectionStrategy。知道这是什么了吗？

Answer 1

我认为这是由于changeDetectionStrategey的错误导入

import { ChangeDetectionStrategy } from '@angular/compiler/src/core';

将其替换为正确的

import { ChangeDetectionStrategy } from '@angular/core';
