Please describe your issue:

Initial Start of the react-typescript template fails.

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in.

I am having the same problem. I am running it on Ubuntu 16.04. Regular react (jsx) template is working fine for me.

[EldoranDev]

I can confirm for Windows 7, Windows 10 and OSX

[malept]

Yeah, this probably isn't OS-specific. But React isn't my area of expertise so I'll defer to one of the other devs.

[MarshallOfSound]

Think I've got this one figured out, testing now 👍

[philcleveland]

Cool. I was playing with versions in package.json and that didn't help. As a side note the @types/react could be updated. The typescript devDependency also doesn't match the Dependency version. Not sure if that is intentional.
