@007lva That fixed the problem, thanks!

Just to clarify, there's a reason I didn't expect this to be a problem. In the second block that complains about "node", that's a successful webpack installation on 2.4 with an old verison of node.

However, in the first block, it never lists node as a problem.

Is this worth a mention that this repo requires node 8.x.x or higher? (not 6 as, mentioned in README).

weird, i just ran it on macOSX 10.13.3, ruby 2.5.0p0 with rails new app --webpack=react. And It works for me.

ytbryan on 26 Feb 2018

@ytbryan What version of rails are you using? Can you try with 5.1.5?

sunnyrjuneja on 26 Feb 2018

Yup

ytbryan on 26 Feb 2018

Not sure, only thing I can think is I'm on Ubuntu and you're on OS X. It works fine for me on 5.1.4.

I tried to replicate this on digital ocean with clean box. I was not able to do so. Closing this issue. Not sure what's up with my machine.

sunnyrjuneja on 28 Feb 2018

It's happening the same on a fresh instance on AWS EC2

kriera on 28 Feb 2018

thanks for chiming in @kriera. how did you install ruby 2.5.0? i tried using ruby-install and chruby.

sunnyrjuneja on 28 Feb 2018

upgraded the system installing ruby 2.5.0 and using it default, chowned the dir from root (you only can install doing su) to ec2-user, and then again same issues, it seems be related to the gem rb-inotify

here is a partial log, some one points to this fork as the solution https://github.com/e2/rb-inotify that's all the info i've atm. thanks

From your logs:

error [email protected]: The engine "node" is incompatible with this module. Expected version ">=6.11.5".
error Found incompatible module

Maybe you should try with Node 8.x.

@sunnyrjuneja Webpacker doesn't support dev server 3.x yet - https://github.com/webpack/webpack-dev-server/blob/master/package.json#L18

error [email protected]: The engine "node" is incompatible with this module. Expected version ">=6.11.5".
error Found incompatible module

We will bump the node versions once Webpacker is upgraded to use webpack v4+

Simply depending on @rails/webpacker isn't enough? Possibly need to add all dependencies to package.json
