Yesterday, my Atom got updated to 1.19.0 automatically. And hydrogen stopped working. So I reinstalled hydrogen (by uninstall and then install again is Settings-Packages). Then after launching atom, I got this error (from Incompatible Packages atom shows). What should I do?
Hydrogen 1.19.0
[email protected] – The module '\?C:Usersway.atompackagesHydrogennode_moduleszeromqbuildReleasezmq.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 49. This version of Node.js requires NODE_MODULE_VERSION 53. Please try re-compiling or re-installing the module (for instance, using npm rebuild ornpm install).

Is there a button on the incompatible package message that says something like "rebuild modules"?
Wow, first of all, it worked.
I've reinstalled these (there is another package incompatible) packages multiple times. And googled around for a very long time. And searched the atom git repo. All with no luck.
I've even noticed there are some buttons there but didn't pay attention what it says, because of the color of the text. I even tried to click the last two buttons, just without trying the first button for even once. Thank you very much.

Glad I could help! I've found the button easy to miss as well.
