gem install rails fails at binding_of_caller gem - ruby-on-rails

Question

I'm trying to get rails working and can't get past a binding_of_caller gem that tries to install with the other gems after running sudo gem install rails. I don't think the gem is required for rails to work, but can't figure out how to skip it, or stop it from trying to install.
Every time the list of gems gets to binding_of_callers I get the following:
Installing binding_of_callers (0.6.9) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

I'm running OSX 10.8.2 and using pow web server with rbenv to manage ruby. I'm also running ruby 1.9.3-p385

Answer 1

Try updating the gem:
$ bundle update binding_of_caller

Answer 2

Before installing Rails, add the gem with the following (also note that the gem name is singular):
$ gem install binding_of_caller
Then run:
$ bundle update rails
Or:
$ gem install rails
(Or whatever rbenv offers)

Answer 3

Ok, so the problem was that the RBENV ruby version wasn't being recognized as the version of ruby being used by the project. So after trying to get rbenv working for a while, I switched back to RVM went through some debugging, and installed some dependencies, I got ruby 2.0.0p0 installed, and recognized as the project ruby. Then I was able to bundle. So to answer my question ... It was a ruby version issue.

Answer 4

Has there been any progress in solving this problem using rbenv?
I'm using rbenv to load jruby 2.0 locally and I would like to continue using this solution rather than rvm.

My ~/.jrubyconf is set to

when I try to install binding of caller I get the following -

Building native extensions. This could take a while...

Now according to the answer that is marked correct in this thread, this is an issue with rbenv, but jruby 1.7.4 is the right version that is sourced and it is operating at 2.0. Shouldn't this work? What am I not understanding?

Answer 5

Looks like youre using Linux. Try following the rails installation by installing ruby and rvm first. It might be cause of an outdated ruby version. throw in the dark though.
