【问题描述】：
我正在升级到 Angular 6
Following the upgrade guide，我遇到如下问题：
> ng update @angular/core
Invalid range: ">=2.1.0"
...这就是我所拥有的一切。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： 失败的地方：
- 手动将所有内容更新到最新版本
- 手动更新 rxjs
- 将 typescript 更新到 2.7.2，然后更新到 2.8.3
- 正在尝试
ng update --all npm install @angular/compiler@6.0.0
在每个步骤之后，角度/核心不会更新并出现上述错误。
现在我已经更新了我的项目，ng -v 显示如下：
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。
更新 2： 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：" 在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 来自 github 线程的有趣线索：
关于 Invalid range: xxx 错误，我快速浏览了一下 在 @angular-devkit/schematics 存储库中查看错误在哪里 抛出和实际发生的事情。
错误被抛出 https://github.com/angular/devkit/blob/master/packages/schematics/update/update/index.ts#L41
如果我查看周围的功能，似乎它正在期待 semver 版本控制的软件包，没有逻辑（由于缺少 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：\
【问题讨论】：
-
在github上也发现了这个问题：github.com/angular/angular-cli/issues/10621
-
@oCcSking 那也是我的线程 :) 问题是，从他们的存储库中提取的干净项目可以使用那里描述的方法进行更新，但它不适用于我的特定项目。
-
我会从一个新的空项目手动迁移
-
你能提供你的 Angular 4 版本的 package.json 吗？在他们提到的文档中升级到下一个主要版本比跳过一个主要版本升级要好......而不是 4-6 make它稳定在 4-5 ，然后是 5-6，如果可能，请创建示例回购！！！
