Bundle update fails on ffi

Question

I'm attempting to do a bundle update on my rails application but I get the following error:

Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it.

Any ideas?

Answer 1

I ran into a problem similar to this yesterday.

I was able to resolve it using these steps:

https://github.com/carlhuda/bundler/blob/1-0-stable/ISSUES.md

Essentially, there was a problem with my bundle and clearing things out and rebuilding things from scratch resolved it.

The steps are repeated here:

# remove user-specific gems and git repos rm -rf ~/.bundle/ ~/.gem/  # remove system-wide git repos and git checkouts rm -rf $GEM_HOME/bundler/ $GEM_HOME/cache/bundler/  # remove project-specific settings and git repos rm -rf .bundle/  # remove project-specific cached .gem files rm -rf vendor/cache/  # remove the saved resolve of the Gemfile rm -rf Gemfile.lock  # try to install one more time bundle install 

Although, given the message in the output text:

You have to install development tools first.

That makes me think you just may not have installed the Apple Xcode Developer Tools. Have you checked that? (I believe they're available in the Mac App Store.)
