推荐答案

您需要将所有 angular 提供的包更新到最新版本，如下所示:

You need to update all angular provided packages to their latest versions as follows:

npm install typescript@2.4 --save-dev

npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest @angular/animations@latest --save

这应该完成所有必要的工作.另外，您还可以更新 angular 5 附带的 angular cli 作为标准版本，如下所示:

This should do all the necessary. Plus you could also update your angular cli that ships with angular 5 as standard version as follows:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest
