Firstly, great article! I really appreciate the effort. I was going step by step on a fresh VM and had a couple issues.
I was getting a “cannot find react-addons-test-utils” error. The article does not mention installing the typings for it which fixed it. The code on GitHub’s typings.json is correct.
Also got an error with phantomjs which is referenced (with a fix) here: https://github.com/ariya/phantomjs/issues/10904
Thought I would add it in case anyone else came across it.
