Strange: after installing Knobs addon, react won't work

I just encountered really strange bug: I am using create-react-app with custom-scripts. Everything working fine, webpack builds page correctly. I have then installed stoybooks, fine, set it up, then copied a story from other project, that was using knobs. As my storybooks shouted that Module not found: Error: Can't resolve '@storybook/addon-centered, I’ve done npm install @storybook/addon-knobs, re-launched webpack with yarn start and… ./src/index.js Module not found: Can't resolve 'react' in 'E:\myapp\src'

That was something unexpected. Tried multiple times with both yarn and npm, but neither worked. I have uninstalled knobs with $ npm uninstall @storybook/addon-knobs and after that my app started working flawlessly again.

What can be causing that? How’s possible knobs deleted react?

My uninstallation log:

Is that right that UNinstalling added 366 packages? I don’t exactly get it.

@pauldariye try reinstalling your dependencies and check that you have react installed as well.

The issue may have been with my node version.
