【问题描述】：

我正在努力学习 RxJs。
在 package.json 中，我已经安装了 rxjs 但仍然为什么它会抛出错误 [ts] 模块 '"c:/Users//Desktop/iooioi/src/main/webapp/node_modules/rxjs/Rx"' 没有默认导出。
在下面提供 package.json
我像这样包含 import { rxjs } from "rxjs";

【问题讨论】：

嘿，这是什么意思

标签： javascript jquery angular typescript rxjs

【解决方案1】：

试试这个

import {Observable,Subject} from "rxjs/Rx";

使用Observable.create()、new Subject() 或

初始化它们

import {Rx} from "rxjs";

然后您可以使用 Rx.Observable.create() 、 new Rx.Subject() 等初始化它们

【讨论】：

嘿，错误得到了修复......如果我像这样使用 import {Observable,Subject} from "rxjs/Rx"; ....你能解释一下，以便将来对我很有帮助
你必须研究 Typescript ES6 模块系统。如何导入模块实际上取决于特定库如何设置其导出 typescriptlang.org/docs/handbook/modules.html
