Any idea what is going on here?

Hello @JamesDullaghan!

First of all, I assume you are using binding_of_caller from rubygems right?

Upgrading your better_errors version has any effect?

Would you mind trying it on master? If it doesn't works, could you share a reproducible snippet of this issue?

[JamesDullaghan]

Yes through rubygems. It works fine with ruby version 2.0.0-p247 and 1.9.3-p484, but not 2.0.0-p353.

I've uninstalled and reinstalled and made sure it's using the most recent version of better_errors

I will try using master now and let you know how that goes.

[JamesDullaghan]

Same error using

  gem 'binding_of_caller', :git => 'git://github.com/banister/binding_of_caller.git', :branch => 'master'

The installed version is 0.7.2 by the way.

better_errors versions is 1.0.1

[pavankat]

so how did you fix this?

[Iteratix]

+1 for this, affects me --Ruby p247, binding_of_caller (0.7.2), better_errors (1.1.0) on Mavericks.

[marzipan101]

+1 ruby 2.1.1p76, binding_of_caller(0.7.2), better_errors(1.1.0) on Mac OS X Lion 10.7.5

[landonwilkins]

ghost of an earlier better_errors in your gems dir maybe?

try running

bundle install --path ~/your_project/bundle/gems

to use a local gems dir for the project (rather than your global)

I was hitting the same error with ruby 2.x

Found that the root issue was i got gem debug_inspector, which is a binding_of_caller dependency with a C extension, installed without a proper Makefile and thus without the debug_inspector.so file in place. Steps to reproduce this situation unknown.

Due to the lack of .so file, require was failing silently here.

Solution for me was to reinstall gem like this:

$ gem uninstall debug_inspector
(project_root) $ bundle

Looks like this issue is solved. If anyone needs to reopen, let me know.
