在从6升级到8的Angular更新过程中令人困惑的不兼容对等项依赖

Question

按照我开始的Angular更新指南（https://update.angular.io/）

$ ng update @angular/cli @angular/core

但这产生了一些不兼容的清单：

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，将其从列表中删除。 然后，我想到可以更改命令以删除更多内容：

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

这给我留下了令人困惑的结果，令人困惑，因为仍然存在两个@angular/http不兼容之一！

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：

1. 对于ngrx-tslint-oftype，我研究了一些方法来改写程序包对打字稿版本的依赖性，但到目前为止，我发现的内容主要是npm shrinkwrap似乎有问题。
2. 为什么@ angular / http仍然是投诉，我该如何解决？

请注意，我也尝试过ng update --all，但这使我与其他与Angular升级无关的软件包不兼容。

我不愿意添加--force；会更愿意能够解决问题，因此这不是必需的。有建议吗？

Answer 1

id | lat | lon | observed | error ----+-----+-----+----------+------- 1 | 1 | 1 | 11 | -1 2 | 2 | 2 | 25 | -5 3 | 3 | 3 | 32 | -2 已被Angular弃用，不再使用（请参见here）。您可以改用@angular/http（请参阅docs）。您将需要使用@angular/common/http

中的HttpClient类

app.module.ts

HttpClientModule

您想使用它的任何地方

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

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

关于import { HttpClient } from '@angular/common/http'; class MyService() { constructor(http: HttpClient) { } ... 的问题。尝试将您的打字稿版本升级到3。
