Question

一个月前，我开始了一个Angular 7项目。现在，我需要将Angular Material包含到项目中并npm i。它最近在版本8中发布，该版本似乎与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中，我发现：

“一旦您和所有依赖项都更新为RxJS 6，请删除 rxjs-compat。”

我应该在rxjs ^ 6上。我需要rxjs-compat才能使用由https://github.com/swagger-api/swagger-codegen生成的swagger client。我试图从package.json中删除"rxjs-compat": "^6.5.2"，但是没有运气。

package.json：

}

所以我的目标是：

能够在项目中使用Angular Material v8
更新为Angular v8
继续使用生成的Swagger客户端

Answer 1

您需要放弃npm的直接操作以升级Angular，并使用新的Angular Schematics来自动完成所有必需的工作。

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

增强其功能并开发自己的代码生成器;）

Answer 2

使用ngrx升级角度

卸载ngrx软件包

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

由于ngrx软件包不可用，在迁移有角度的核心软件包时将触发错误

要解决问题，请重新安装ngrx软件包

运行命令ng update @ angular / core-从7-到8-仅迁移

完成角度升级

更新Angular 7-> Angular 8时出错
