React - Uncaught TypeError: Cannot read property 'func' of undefined

Question

I\'m receiving the error:

Uncaught TypeError: Cannot read property \'func\' of undefined

Yet I have no idea why, I\'ve Googled

Answer 1

It's very easy to resolve.

This is happening because you are using react-router version 2.0.0

Just enter "npm install --save react-router@3.2.0"

It should just work fine now.

Answer 2

It looks like a react-router bug (related to prop types.) It's working on react-router 3.2.0
