将Angular 5升级到6时,我得到了不兼容的对等依赖(使用ng update @ angular/core)

Question

我正在尝试按照本指南将我的Angular应用程序从v5更新到v6 .

我成功运行了所有这些命令:

npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli

问题是我在运行此命令时出错:

ng update @angular/core
                  Package "@angular/flex-layout" has an incompatible peer dependency to "rxjs" (requires "^5.5.0", would install "6.2.0").
                  Package "@angular/compiler-cli" has an incompatible peer dependency to "typescript" (requires ">=2.7.2 <2.8", would install "2.6.2")
Incompatible peer dependencies found. See above.

我不知道如何处理这个问题并且我不想自己尝试以避免破坏应用程序.

有人可以建议做什么？

我目前的依赖关系如下:

  "dependencies": {
    "@angular/animations": "^5.2.10",

解决这个问题的方法是添加一个--force标志.

ng update @angular/core --force

希望这会帮助别人,我终于可以通过手动更新一些角度包来解决问题(使用npm)

npm i @angular/cdk@6 @angular/compiler-cli@6 @angular/material@6 rxjs@6 --save

之后ng更新命令可以工作(有一些警告,但至少我们通过了ng update @ angular/core)

ng update @angular/core

在进行如下强制更新后，为我解决了该问题：

ng update --all --force

它基本上避免/忽略所有依赖项检查，并在适用的情况下更新所有软件包。尽管通常不建议这样做，但由于其他建议似乎对我不起作用，因此我不得不以这种方式进行更新。
