I'm trying to install this gem on Raspbian.

Install RBENV and Ruby 2.15 and all is well. I try to launch the server, it starts. I try to access the page, it just sits there, and about a minute later it produces this:

pi@raspberrypi:~/test$ wagn server

Seems happening inside therubyracer.
Could you ask the author of it?

[basilmir (Mir S.)]

Yes! Managed to narrow it down to 'therubyracer' myself. Apparently it's a known issue with ARM devices, essentially the Raspberry Pi 2 and older. Gitlab seems to have the same issues as it relies on it too.

To fix this you need to install a precompiled node js package via apt-get or similar and edit your Gemfile and remove (put # before the line) gem 'therubyracer'.

I guess we can close this.
