无法升级到角度6，无效范围

Question

我正在升级到角形6

遵循升级指南，我遇到了以下问题：

> ng update @angular/core                
Invalid range: ">=2.1.0"

...and，这就是我的全部。没有其他警告，也没有任何其他描述。在我的项目中，也没有匹配的">=2.1.0“字符串。

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：不起作用的东西：

• 手动将所有内容更新到最新版本
• 手动更新rxjs
• 将打字本更新为2.7.2，然后更新为2.8.3
• 试图ng update --all
• npm install @angular/compiler@6.0.0

在这些步骤中的每一个步骤之后，角/核心都不会用上面提到的错误来更新。

现在我已经更新了我的项目，ng -v显示了以下内容：

但是，尽管它显示了6.0，但项目未能运行(角/核心包中的错误)，执行命令ng update @angular/core仍然会产生相同的错误消息。

Update2: --我正在使用与https://github.com/akveo/ngx-admin兼容的Range4.0版本作为项目基础。不过，它有很多修改。

Update3：“在手动将所有内容更新到6.0，并将@R角/core更新为5.2之后，问题仍然存在(无效范围：">=2.1.0") package.json如下：

Update4:这是来自布约恩的github线程的一个有趣的线索

关于无效的范围: xxx错误，我快速地查看了@ and /示意图回购，以查看错误在哪里抛出，以及实际发生了什么。 在https://github.com/angular/devkit/blob/master/packages/schematics/update/update/index.ts#L41引发错误 如果我看一下周围的函数，似乎它只期望，而没有逻辑(缺少更好的术语吗？)版本控制。

这可能是核心问题，但我仍然看不出如何解决这个问题:\

Answer 1

终于！实际上已经解决了一半，因为package.json中提到的内部依赖关系。

一次又一次地检查了下面的所有错误。

Invalid Range: ">=2.1.0"
Invalid Range:">=2.0.0|| >=4.0.0-beta"
Incompatible peer dependencies 
Invalid Range:">=4.0.0

因为这些模块

ng2-completer
angular-table
ng2-smart-table
ng2-handsontable
ng2-slim-loading-bar
@ngx-translate/core 
@ngx-translate/http-loader,

它们中很少有可以升级的，其中提到6.0.0角版本作为它们的对等依赖项。

但是很少有人仍然使用旧的版本2/4

通过解析所有对等依赖项，能够解决错误(省略了未升级的错误)

如果您所依赖的外部依赖项没有使用新版本，那么请寻找替代方案！

编辑的

将通过升级到角6.0.1来解决这个问题，作为

角/devkit已经更新->包/原理图/更新/更新/index.ts

哪一个固定的角度？

参考文献：https://github.com/angular/devkit/pull/901/commits/6cdd4f12afc7882f0db6ecd97f26802ff0526e35 (作为yurzui，ForestG提到)

希望这会有帮助！

Answer 2

经过大量的研究，我提出了以下解决方案，并成功地将我的本地项目更新为角6.0.1：

1. npm安装@角/{动画，普通，编译器，编译器-cli，核心，窗体，http，平台-浏览器，平台-浏览器-动态，平台-服务器，路由器}@‘6.0.1’
2. ng更新rxjs
3. npm安装rxjs@6 rxjs-compat@6 -保存
4. 更新@角/核心
5. ng update @角/材料
6. npm安装类型2.7.0=‘>=2.7.0 <2.8.0’

Answer 3

我在这里也有类似的问题，但我的“无效范围”不一样：

Invalid range: ">=2.3.1 <3.0.0||>=4.0.0"

经过几个小时的挣扎，试图缩小导致这种依赖的原因，我发现我错误地有两个“ng引导”依赖关系:(

  "dependencies": {
    "@angular/animations": "^5.2.0",
    "@angular/cdk": "^6.0.1",
    "@angular/common": "^5.2.0",
    "@angular/compiler": "^5.2.0",
    "@angular/core": "^5.2.0",
    "@angular/forms": "^5.2.0",
    "@angular/http": "^5.2.0",
    "@angular/platform-browser": "^5.2.0",
    "@angular/platform-browser-dynamic": "^5.2.0",
    "@angular/router": "^5.2.0",
    "@fortawesome/fontawesome": "^1.1.8",
    "@fortawesome/fontawesome-free-webfonts": "^1.0.9",
    "@ng-bootstrap/ng-bootstrap": "^2.0.0",
    ...
    "ng-bootstrap": "^1.6.3",       <<< WRONG!!
    "rxjs": "^5.5.6",
    "zone.js": "^0.8.19"
  },

所以，在用npm删除了npm之后，ng update @angular/core @angular/compiler-cli rxjs很好地完成了！:)
