No rendering - react issue following upgrade

[alex314159]

Hi,

thanks for the great work with this project - saves so much time to quickly deploy enterprise apps!

I've had to reinstall everything on a new computer and while my projects compile, nothing renders. I get this in the console:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Thank you for the help!!

I havn't tested anything with reagent 1.x yet (including re-frame itself). Does it work with reagent 0.10.0 ? @alex314159

[alex314159]

thanks - not working, I've tried downgrading everything as well to [reagent "0.8.1"] [re-frame "0.10.9"] [re-com "2.6.0"]

which is my existing version, and react and react-dom 16.8.6. I suspect there's smthg fundamentally wrong with my react / reagent installation more than re-com itself.

just copied my whole node_modules folder from old machine which made it work - thanks
