一个月前，我开始了一个 Angular 7 项目。现在我需要将 Angular Material 包含到项目npm i中。它最近发布的版本 8 似乎与 Angular 7 不兼容。

所以我开始更新 Angular 7 → Angular 8: ng update @angular/cli @angular/core。这给了我一个错误：

$ng update @angular/cli @angular/core

Package "@ngrx/core" has an incompatible peer dependency to "rxjs" (requires "^5.0.0-beta.12", would install "6.5.2").

Incompatible peer dependencies found. See above.

在本指南https://update.angular.io/#7.0:8.0我发现：

“一旦您和您的所有依赖项都更新到 RxJS 6，请删除 rxjs-compat。”

我应该在 rxjs^6 上。我需要rxjs-compat能够使用我swagger client生成的https://github.com/swagger-api/swagger-codegen。我试图"rxjs-compat": "^6.5.2"从 package.json 中删除，但没有运气。

所以我的目标是：

  1. 可以Angular Material v8在项目中使用
  2. 更新到Angular v8
  3. 继续使用生成的 Swagger 客户端

使用 ngrx 升级 Angular 的步骤

卸载 ngrx 软件包

运行命令 ng update @angular/cli @angular/core

由于ngrx包不可用，迁移角核心包时将触发错误

解决问题重新安装ngrx包

运行命令 ng update @angular/core --from 7 --to 8 --migrate-only

完成角度升级

您需要放弃npm直接操作来升级 Angular，并采用自动完成所有必需工作的新 Angular Schematics。

改为使用ng update并从那里更新每个包，您可以使用 更新其他库npm，但 Angular 及其库的新范例是通过 Schematics 。

拥抱他们的力量并开发自己的代码生成器；）
