Question

我正在尝试在this guide之后将我的Angular应用从v5更新到v6。

我已成功运行所有这些命令：

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

问题是运行此命令时出错：

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＆amp;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吗？

我目前的依赖关系如下：

  "dependencies": {
    "@angular/animations": "^5.2.10",
    "@angular/cdk": "^5.2.5",

Answer 1

解决此问题的方法是添加--force标志。

ng update @angular/core --force

Answer 2

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

Answer 3

在进行如下所示的强制更新后，该问题已为我解决：-

ng更新--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。

Answer 4

我能够使用以下方法来绕过有关不兼容对等方的消息：

ng更新--all

它更新了所有需要更新的软件包。

Answer 5

不要强制更新，以后会出现意外结果。请改用以下npm安装，然后重试。

npm install -g @angular-devkit/schematics-cli

Answer 6

您可以尝试：

npm i --save-dev @angular/cli@version @angular/core@version

然后您可以运行ng update --all 这对我有用。

我在使用Incompatible peer dependencies found. See above.更新@angular/cli和@angular/core时得到了ng update --all。

Answer 7

此命令在我的情况下有效：

npm install --force @angular/cli@version @angular/core@version

这里的版本可能是您要升级的6,7,8,9,10

Answer 8

运行 --force 不是正确的选择。因为它在抱怨 rxjs 和 typescript，所以你需要先升级它。完成后，您可以运行 angular update 命令

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）
