Bundle update fails on ffi

Question

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

Installing ffi (1.0.11) with native extensions Unfo         


        

Answer 1

Just in case try to run

sudo /usr/bin/gcc

You'll probably see license agreement, so scroll thgough it, type "agree" and try to install gem again.

Answer 2

Mac OSx 10.10.2 yosemite

 CC=/usr/bin/i686-apple-darwin11-llvm-gcc-4.2 gem install ffi

and thats it -check that you have 4.2 compiler in /usr/bin that you can hook into

ls /usr/bin|grep gcc|grep 4.2

You do not have to wipe out all of your local gems or override symlinks to do this - its a waste of time and will likely create more problems then it solves.

please note, your bin path may be different if you needed to install via brew

brew install apple-gcc42 

Answer 3

Please note:

If you have recently updated Xcode, you may just need to open Xcode and accept the latest agreement.

I had the same issue and had recently installed an update to Xcode (v6.1) and solved it with these steps:

1. open Xcode
2. accept new agreement
3. rerun bundle update

Answer 4

For me I just didn't have gcc installed, solve in Ubuntu by:

sudo apt install build-essential

Answer 5

For Xcode 5 and later:

$ xcode-select --install

to install the Command Line Tools.

Answer 6

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.)
