我无法从npm安装任何节点模块.

npm install socket.io

上面的命令产生了以下输出,它无法安装socket.io

npm http GET https://registry.npmjs.org/socket.io

当尝试从node_modulestypescript编译器中的类扩展类时抛出一个错误说:

Property 'source' is protected but type 'Observable<T>' is not a class derived from 'Observable<T>'.

这只发生在基类来自a时node_module.

基类看起来像:

import {Observable} from "rxjs/Observable";
export abstract class TestBase<T> {

    request(options: any):Observable<T> {
        return Observable.throw(new Error('TestBase is abstract class. Extend it and implement own request method'));
    }
}

在项目中对其进行子类化:

import {Observable} from "rxjs/Observable";
import {TestBase} from "@org/core";

class SocketResponse {

}

class Socket {
    request(): Observable<SocketResponse> {
        return new Observable.of(new SocketResponse());
    }
}

export class Sub extends TestBase<SocketResponse> {
    request(options:any):Observable<SocketResponse> …

我有一个全新安装yarn(通过npm install yarn -g)并试图安装一些包

yarn add vue-loader babel-loader style-loader css-loader file-loader webpack

我在安装过程中收到了一些警告,例如

warning "vue-loader@13.3.0" has unmet peer dependency "vue-template-compiler@^2.0.0".

这究竟是什么意思,具体而言:为什么不自行yarn安装这些依赖项？(如果需要的话)

关于同一主题的姐妹问题(关于npm)产生一些答案,其表明i)更新npmii)删除node_modules因为存在npm关于处理依赖性的错误.

这种警告的状态是什么yarn？这真的是一个警告(=我可以丢弃的东西)？我不能丢弃它们(webpack构建失败)并且必须手动安装它们.同时,安装了很多依赖项,所以我不明白为什么会错过一些(虽然它们可以手动安装)

有没有办法撤消命令npm update？我运行命令,现在我有一堆未满足的依赖项和一些错误.

我正在尝试手动重新安装并修复所有错误但是有谁知道如何基本上恢复npm update？

npm使用后返回以下消息 npm list -g

npm ERR! missing: atom-package-manager@*, required by undefined@undefined

我Alert Component在我的ionic 2项目中导入如下:

import {Alert } from 'ionic-angular';

用法:

let alert = this.alert.create({
    title: 'New Friend!',
    subTitle: 'Your friend, Obi wan Kenobi, just accepted your friend request!',
      buttons: ['OK']
    });
alert.present();

但我的错误是: Property create does not exist on type Alert.
