I copied the package.json file from this website, executed npm install and received the following errors:

The error message clearly states that your project lacks the typings manifest required by the npm client when installing the TypeScript typing definition files upon executing the postinstall script.

In order to workaround this issue, please save this file in your workspace and try running npm i again.

All in all, I'm really sorry to inform you that "Learning Angular 2" is too outdated already. The book was published when Angular 2 hit RC.1 back in May'16 in the hopes that the Angular framework would not contain breaking changes from that moment on. It turns out that such version tagging was more of an experiment conducted by the Angular 2 team and the framework still feature continuous breaking changes until its final release. While the book still provides an accurate picture of the framework philosophy, I'm afraid the API describe in its pages does not stay relevant anymore.

Still, upgrading the code may help to see how you should do it now. The book is good for understanding the framework and the uptodate code may show the changes. It's better han nothing I think. Apart from the navbar css I could use Angular-Cli to get chapter 1 working. Bootstrap would not install and a copy of the css files only worked partially, but maybe I did something wrong.

Please refer then to this branch/folder: https://github.com/deeleman/learning-angular2/tree/v2.1.2/chapter_01

Folder chapter_01 in branch v2.1.2 is fully up to date with the latest Angular edition, and hopefully will be in help for those now diving into Angular 2. Chapters 3-10 will be released soon.

For the record, and following current design patterns in the Angular 2 arena, the required typings are no longer installed through the typings CLI; but as npm dependencies instead.

Hope this helps.
