Angular 从 6 更新到 8 期间令人费解的不兼容对等依赖性

Question

按照 Angular 更新指南 (https://update.angular.io/)，我从

开始

$ ng update @angular/cli @angular/core

但这产生了一些不兼容的列表：

Package "codelyzer" has an incompatible peer dependency to "@angular/core" (requires ">=2.3.1 <7.0.0 || >6.0.0-beta <7.0.0" (extended), would install "8.1.0").
Package "@ngrx/router-store" has an incompatible peer dependency to "@angular/router" (requires "^6.0.0" (extended), would install "8.1.0").
Package "ngrx-tslint-oftype" has an incompatible peer dependency to "typescript" (requires "^2.8.3", would install "3.4.5").
Package "@angular/http" has an incompatible peer dependency to "@angular/platform-browser" (requires "6.1.3" (extended), would install "8.1.0").
Package "@angular/material" has an incompatible peer dependency to "@angular/core" (requires ">=6.0.0-beta.0 <7.0.0" (extended), would install "8.1.0").
Package "codelyzer" has an incompatible peer dependency to "@angular/compiler" (requires ">=2.3.1 <7.0.0 || >6.0.0-beta <7.0.0" (extended), would install "8.1.0").
Package "@angular/material" has an incompatible peer dependency to "@angular/core" (requires ">=6.0.0-beta.0 <7.0.0" (extended), would install "8.1.0").

我更新了 codelyzer 以将其从列表中删除。然后我想我可以更改命令以删除更多：

$ ng update @angular/cli @angular/core @ngrx/store @angular/material @angular/http

这给我留下了这个令人费解的结果，令人费解的是两个 @angular/http 不兼容性之一仍然存在！

Package "ngrx-tslint-oftype" has an incompatible peer dependency to "typescript" (requires "^2.8.3", would install "3.4.5").
Package "@angular/http" has an incompatible peer dependency to "@angular/core" (requires "7.2.15", would install "8.1.0")

所以我有两个问题：

对于 ngrx-tslint-oftype，我研究了覆盖包对打字稿版本的依赖的方法，但到目前为止我发现的——主要是npm shrinkwrap——似乎有问题。
为什么@angular/http 仍然是一个投诉，我该如何解决？

请注意，我也尝试了 ng update --all，但这给了我一些与其他软件包不兼容的问题，与 Angular 升级无关。

犹豫要不要加一个--force；更愿意能够解决问题，所以这不是必需的。建议？

Answer 1

@angular/http 已被 Angular 弃用，不再使用（参见 here). You can make use of @angular/common/http instead (See docs）。您将需要使用 HttpClientModule

中的 HttpClient class

app.module.ts

import { HttpClientModule } from '@angular/common/http';

@NgModule({
 imports: [
   BrowserModule,
   HttpClientModule
 ],
...

随时随地使用

import { HttpClient } from '@angular/common/http';

class MyService() {
    constructor(http: HttpClient) { }
...

至于ngrx-tslint-oftype的问题。尝试将您的打字稿版本升级到 3。
