angular - 升级 Angular 6 时的 Webpack 警告

Question

我将 Angular 从版本 6.0.0 升级到了 6.1.3。运行后ng update @angular/core我收到以下警告：

npm WARN @ngtools/webpack@6.0.8 requires a peer of typescript@~2.4.0 || 
~2.5.0 || ~2.6.0 || ~2.7.0 but none is installed. You must install 
peer dependencies yourself.

是什么意思peer of typescript？根据ng -version，安装了打字稿。@ngtools/webpack 正在寻找什么版本？

ng-版本：

Angular CLI: 6.1.4
Node: 8.9.1
OS: win32 x64
Angular: 6.1.3

将“@angular-devkit/build-angular”更新为 0.7.4 以修复上述错误。
