我正在升级到 Angular 6
按照升级指南，我遇到以下问题：
> ng update @angular/core
Invalid range: ">=2.1.0"
......这就是我所拥有的。没有其他警告或任何其他描述。在我的项目中，“>=2.1.0”字符串也不匹配。
ng -v结果：
Angular CLI: 6.0.0
Node: 9.4.0
OS: linux x64
Angular: 4.1.3
... animations, common, compiler, compiler-cli, core, forms
... http, platform-browser, platform-browser-dynamic
... platform-server, router, tsc-wrapped
Package Version
-----------------------------------------------------------
@angular-devkit/architect 0.6.0
@angular-devkit/build-angular 0.6.0
@angular-devkit/build-optimizer 0.6.0
@angular-devkit/core 0.6.0
@angular-devkit/schematics 0.6.0
@angular/cli 6.0.0
@ngtools/webpack 6.0.0
@schematics/angular 0.6.0
@schematics/update 0.6.0
rxjs 6.1.0
typescript 2.3.2
webpack 4.6.0
更新：事情没有奏效：
- 手动将所有内容更新到最新版本
- 手动更新 rxjs
- 将打字稿更新到 2.7.2，然后更新到 2.8.3
- 尝试去
ng update --all npm install @angular/compiler@6.0.0
在这些步骤中的每一个之后，角度/核心不会因上述错误而更新。
现在我更新了我的项目， ng -v 显示以下内容：
Angular CLI: 6.0.0
Node: 9.4.0
OS: linux x64
Angular: 6.0.0
... cli, compiler, core
Package Version
-------------------------------------------------------------
@angular-devkit/architect 0.6.0
@angular-devkit/build-angular 0.6.0
@angular-devkit/build-optimizer 0.6.0
@angular-devkit/core 0.6.0
@angular-devkit/schematics 0.6.0
@angular/animations 5.2.10
@angular/common 5.2.10
@angular/compiler-cli 5.2.10
@angular/forms 5.2.10
@angular/http 5.2.10
@angular/platform-browser 5.2.10
@angular/platform-browser-dynamic 5.2.10
@angular/platform-server 5.2.10
@angular/router 5.2.10
@ngtools/webpack 6.0.0
@schematics/angular 0.6.0
@schematics/update 0.6.0
rxjs 6.1.0
typescript 2.8.3
webpack 4.6.0
但是尽管它显示 6.0，但项目无法运行（角度/核心包中的错误），并且执行命令ng update @angular/core仍然会产生相同的错误消息。
Update2： 我使用https://github.com/akveo/ngx-admin的 angular 4.0 兼容版本作为项目基础。虽然有很多修改。
更新3：“ 手动将所有内容更新到6.0，并将@angular/core更新到5.2后，问题仍然存在（无效范围：> = 2.1.0”）package.json如下：

更新 4： 这是Bjeaurn的 github 线程中的一个有趣的线索：
关于 Invalid range: xxx 错误，我快速浏览了 @angular-devkit/schematics 存储库，了解错误在哪里引发以及实际发生了什么。
在 https://github.com/angular/devkit/blob/master/packages/schematics/update/update/index.ts#L41抛出错误
如果我查看周围的功能，似乎它只需要 semver 版本的包，而不是合乎逻辑的（由于缺乏更好的术语？）版本控制。
这可能是核心问题，但我仍然看不到如何解决这个问题：\
