Unable to install prophet from Gemfile

[lepepe]

Recently I upgrade my rails app to version 6.0 and prophet to 0.2.5; everything is running fine on development but when deploying my app to multiples droplets on Digital Ocean and to different stages I'm getting the error below.

I installed the gem manually without any issue; what I don't understand is that on some stages is deployed successfully, after the second one I started getting the error. Any idea what I could be doing wrong?

Hey @lepepe, it looks like it's failing to compile the model, but don't see the reason. Can you paste the full output?

Hi @ankane here is the full output. Could be related with memory issue?

Yeah, it looks like the error is g++: internal compiler error: Segmentation fault (program cc1plus), but my guess is it's a memory issue if it works some of the time but not others.
