Error after update: Cannot resolve module 'react/lib/ReactMount'
<p>So I was trying to put my react-webpack app on Heroku when I started getting the error that ReactMount was not at React/lib/ReactMount. Then I tried a lot of different stuff and ended up trying to create a new project with the same react-webpack generater. And now I get the same mistake even when running on localhost meaning that it must be due to an update somewhere, right?</p>

<p>Does anyone know anything about this?</p>

<p>I have the following dependencies:</p>
