更新到Angular 7-@ angular / animation错误

Question

当我运行 ng update @ angular / core 时，出现以下错误：

Package "@angular/animation" has an incompatible peer dependency to 
"@angular/core" (requires "4.0.0-beta.8" (extended), would install "7.0.0").

我能够毫无问题地运行ng update @angular/cli

我已经跑过npm update

这是我的ng版本：

Angular CLI: 7.0.2
Node: 8.12.0
OS: win32 x64
Angular: 6.1.10
... common, compiler, compiler-cli, core, forms, http
... language-service, platform-browser, platform-browser-dynamic
