Example is not working

[DamirKh]

Hello, Conan! Just clone pyreact to try it, but instead of the clock I saw ¨click the clock for a new random color¨. In which direction should I see to debug it? (I did try it on RaspberryPi if it matter https://www.raspberrypi.org/) Additions:

Uncaught Error: Clock(...): Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null. at invariant (react-dom-16.0.0.js:65) at reconcileChildFibers (react-dom-16.0.0.js:10539) at reconcileChildrenAtPriority (react-dom-16.0.0.js:11198) at reconcileChildren (react-dom-16.0.0.js:11189) at finishClassComponent (react-dom-16.0.0.js:11325) at mountIndeterminateComponent (react-dom-16.0.0.js:11486) at beginWork (react-dom-16.0.0.js:11672) at performUnitOfWork (react-dom-16.0.0.js:13644) at workLoop (react-dom-16.0.0.js:13753) at HTMLUnknownElement.callCallback (react-dom-16.0.0.js:1527)
