title: ReactJS: "Error: React.createElement is not a function"
body: <p>I have been using React for a while now, and my version was horribly out of date. I updated to 0.12 without incident. Then I tried upgrading react tools as well. That is when everything broke. Now I am getting the following error: "Error: React.createElement is not a function". Other than a vague idea that this probably has something to do with the changes to the JSX transformer, I have no idea why upgrading react tools is leading to this error. Any help would be appreciated</p>
