angular - 如何使用深度相等(Angular 7)

Question

通过 VS 代码自动导入:

import deepEqual = require('deep-equal');

不起作用:

error TS1202: Import assignment cannot be used when targeting ECMAScript modules. Consider using 'import * as ns from "mod"', 'import {a} from "mod"', 'import d from "mod"', or another module format instead.

然后我尝试这样做:

import * as deepEqual from 'deep-equal';

error TS2497: Module '"path/@types/deep-equal/index"' resolves to a non-module entity and cannot be imported using this construct.

像这样:

import {deepEqual} from 'deep-equal';

error TS2305: Module '"C:/Projects/ManagerServer/Src-LoyaltyCoin.ManagerServer.Core/ManagerWeb/ClientApp/node_modules/@types/deep-equal/index"' has no exported member 'deepEqual'.

我不知道如何导入它。如果对此没有解决方案，请建议我使用另一个库来比较 Angular 7 的对象。

将脚本添加到您的 angular.json 文件中:

scripts: [
  "node_modules/deep_import/name.of.minified.file.js"
]

然后在你的组件中声明一个变量:

import { Component } from '@angular/core';
....
declare const deepEqual: any;

或者，您可以找到 typings为此并安装它们，并像任何其他依赖项一样导入它:

import * as deepEqual from 'deep-equal';

编辑 只是语法问题。我建议你open the repository并查看语法。正确的是

import deepEqual from 'deep-equal';

正如您在此 stackbltiz 中看到的那样
