我正在使用此命令ng update @angular/cli @angular/corefor将角度版本从 6 更新到 8，但它显示了以下问题。
Package "@nguniversal/module-map-ngfactory-loader" has an incompatible peer dependency to "@angular/core" (requires ">=7.0.0-rc.0 <8.0.0||>=6.0.0-rc.0 <7.0.0", would install "8.2.5").
Package "@nguniversal/module-map-ngfactory-loader" has an incompatible peer dependency to "@angular/common" (requires ">=7.0.0-rc.0 <8.0.0||>=6.0.0-rc.0 <7.0.0", would install "8.2.5").
Package "@nguniversal/module-map-ngfactory-loader" has an incompatible peer dependency to "@angular/platform-server" (requires ">=7.0.0-rc.0 <8.0.0||>=6.0.0-rc.0 <7.0.0", would install "8.2.5").
发现不兼容的对等依赖项。看上面。
