Bundle update fails on ffi

问题:

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

Any ideas?

回答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.)

回答2:

For Xcode 5 and later:

$ xcode-select --install

to install the Command Line Tools.

回答3:

Once installed gcc-4.2 from brew, you need to create symlink of it:

ln -s /usr/bin/gcc /usr/bin/gcc-4.2

回答4:

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.

回答5:

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

回答6:

Installing "Command Line Tools" via Xcode did the trick.

If you have Xcode 4.5 open Preferences > Downloads > Select Components tab and click Install next to Command Line Tools.

Although I installed from Xcode, you can also download the package without it from Apple's Developer Downloads and searching for "Command Line Tools".

回答7:

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

sudo apt install build-essential

回答8:

I had to accept the Xcode User licence:

Running sudo xcrun cc should bring up the cli version of the Xcode license agreement. Another option is to open Xcode.app and agree in the GUI.

Possibly caused by updating OSX.

回答9:

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 

回答10:

Also method:

export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
bundle update

ffi.h is to be found in ${SDKROOT}/usr/include/ffi/ffi.h.

Ubuntu Trusty LTS 14.04

Needed to switch from ruby 2.2.1 to 2.3.0 to support newer gem versions in Rails app.

Solution:

1. rvm get stable
2. rvm remove 2.3.0
3. rvm install 2.3.0
4. bundle install
