我正在按照官方文档进行升级。
这一步已经顺利完成，没有任何错误。
ng update @angular/core@8 @angular/cli@8
下一步失败了。
ng update @angular/core @angular/cli
The installed Angular CLI version is older than the latest stable version.

Package "@angular/platform-browser-dynamic" has a missing peer dependency of "tslib" @ "^1.10.0".
Package "@ngtools/webpack" has an incompatible peer dependency to "typescript" (requires ">=3.4 < 3.6", would install "3.7.5").
Incompatible peer dependencies found.
Peer dependency warnings when installing dependencies means that those dependencies might not work correctly together.
You can use the '--force' option to ignore incompatible peer dependencies and instead address these warnings later.
我检查了node_modules，发现tslib的正确版本已安装。
我手动添加了tslib条目，并运行npm install以查看错误是否消失。
