Mac: Failed to build gem native extension

When installing ruby on rails, vagrant, rmagick, sqlite3-ruby, mysql or any other software using ruby native extensions, you might get the following error message:

I got this error because I was on a new Mac and didn’t have XCode installed on this machine (using another one for Mac development). And since it’s over 1 GB of disk space I’d need for Xcode, I wanted to avoid having to install it just to get this other stuff installed. The alternative are the “command line tools”. So I went to http://developer.apple.com/downloads/, logged in with my Apple ID, downloaded the latest version of the “Command Line Tools (OS X Mountain Lion) for Xcode” and installed them.

But even with the command line tools install, I was still getting the following error message (which was also there before installing the tools):

Then I had a look at config.log, located there (you might have a different path, when using a newer version):

And foung the following error:

The solution is to use xcode-select but it took me a few tries to find out what I was supposed to use as path without Xcode installed:

This error was gone but I got a few error messages like this:

Looking at the man pages:

xcrun provides a means to locate or invoke coexistence- and platform-aware developer tools from the command-line, without requiring users to modify makefiles or otherwise take inconvenient measures to support multiple Xcode tool chains.

Well, it didn’t really help me much…

The command causing looked like this:

So xcrun just gets a command line as parameters. So first I checked that cc was working:

Then since just calling cc was working, I was wondering why I’d need xcrun… Maybe the solution is just to create my own xcrun just executing the command line provided as parameters.

First I made a back up of xcrun, then created a shell script there:

Now in vi, I’ve put the following contents in xcrun:

It just execute the same command line but without the first xcrun. Of course, you need to give it execute rights:

And then executing gem install finally worked ! I guess there is probably a cleaner way to do it but at least I got it working even though it was late at night and I was almost sleeping on the keyboard !

Update: The trick with xcrun might cause problems installing some other software e.g. osxfuse. So you might have to remove it afterwards:

If you need it again, you can restore it like this:

• i do not believe this is an issue with bundler

this looks like a permissions error. Bundler expects that you have permission to write to the directory the error:
Permission denied @ dir_s_mkdir — ./.gem.20150131-61502-djrp3
as well as an error that came from mkdir both suggest incorrect permissions. If you are on OSX user this is probably due to the inappropriate use of sudo. OSX by convention doesn’t use sudo for much of any CLI installation unless you are using Macports

if you are using brew try brew doctor for help. or uninstall and reinstall rbenv (including it’s dependencies from

/.rbenv ) the try reinstalling this.

also rbenv doesn’t install bundler by default it is plausible that you are using system bundler to try and install nokogiri even though you are using rbenv’s ruby.

if you run which bundler and the return value is not rbenv something something try this:

gem install bundler && rbenv rehash

TimMoore commented Feb 11, 2015

I agree, this looks like filesystem permissions are set up incorrectly. Check permissions on your project directory and on /Users/ratciti/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/nokogiri-1.6.6.2 (I believe it changes to the gem directory before building) to make sure you can write files as the user that you’re running Bundler with.

willbowling commented Apr 20, 2015

What resolved my issue was to install bundler without sudo. «gem install bundler».

edwinxico commented Jun 22, 2015

Installing bundle «gem install bundler» also solved my similar issue

chargio commented Sep 26, 2015

I was using rbenv in Fedora and got the same message. I couldn’t understand why.
At the end, it was a lack of underneath packages, it was solved installing them:
sudo dnf install ruby-devel cmake mariadb-devel rubygems-devel
bundler update
bundler install

jclaret commented Sep 29, 2015

it works for fedora 22 too.

Viktorminator commented Nov 28, 2015

kmcmcurtis7 commented Jan 1, 2016

Thanks for the info! I ran into this and this resolved the problem quickly.

Abdull commented Feb 19, 2016

sudo apt-get install ruby2.2-dev

zoomwebstudio commented Mar 8, 2016

This solution works perfectly for me. thanks to @Abdull
sudo apt-get install ruby2.2-dev
and after I ran
bundle install

shrinivas91 commented Mar 29, 2016

I used sudo apt-get install ruby2.2-dev
But I’m getting the following error:

My problem is this «Make sure that gem install debugger -v ‘1.6.8’ succeeds before bundling». I’ve tried install it, but the problem continues.

willbowling commented Apr 23, 2016

Should probably run gem bundler install? If that is what you intend to use.
Ie «bundle exec» etc.

I also personally use rvm for my ruby versions. It seems more maintainable.

I met a snag as the following:

The version of Ruby installed is ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux-gnu]

Could anyone please tell me why and how to tackle it? Thanks very much.

parkr commented Apr 18, 2015

Did you also install the development headers? They don’t seem to be present:

eduOSS commented Apr 18, 2015

Do you mean installing ruby-dev? But the error remains the same after that step.

apt-get install ruby-dev

parkr commented Apr 19, 2015

You need the Ruby 2.1 dev headers. Maybe @envygeeks would know more on how to get them.

envygeeks commented Apr 19, 2015

sudo apt-get install ruby2.1-dev for 2.1.

eduOSS commented Apr 20, 2015

envygeeks commented Apr 20, 2015

There is something wrong with your apt source, Brightbox Ruby does have ruby2.1-dev but you can’t even reach it, which leads me to believe you need to remove the source and readd it.

I get this error when running sudo gem update github-pages . Is this related?

@parkr Strange. I’m not running El Capitan (still on Mavericks).

Check out the SDK version in that stack trace.

Closing as stale.

if using ruby version 2.2 or greater you need to have ruby2.2-dev

sudo apt-get install ruby2.2-dev

You might take a look

I am having a similar error on RHEL 7. I have also installed ruby-devel and am receving this error:

parkr commented Jan 17, 2017

@midacts It looks like you’re using a custom version of Ruby installed to /opt/rh/rh-ruby22/root/usr . Installing ruby-devel won’t install the headers into this location, but into /usr/share/include/ruby.h instead. You will need to install the headers for the binary located at /opt/rh/rh-ruby22/root/usr/bin/ruby .

inscrutabledude commented Feb 20, 2017

Hi @parkr Could you elaborate on how to do that? I’m a complete ruby noob, I’m just trying to get the knife-azure gem installed for chef, and am getting this message: current directory: /var/lib/gems/2.3.0/gems/nokogiri-1.7.0.1/ext/nokogiri

mkmf.rb can’t find header files for ruby at /usr/lib/ruby/include/ruby.h

I tried this command: sudo apt-get install ruby2.3-dev
Then tried to install gem again, got: E: Unable to locate package ruby2.3.0-dev

Any advice appreciated!

I’ve installed git for windows,JRuby,rjgit and gollum serval days ago,and they work well. But gollum doesn’t recognize the form of table.When i install github-markdown by the command of gem install github-markdown,the error comes.

I don’t know why I’m being pinged here, but switch to Linux on Windows, it’s better.

Hi there, sorry for respawning the thread but I preferred to do so as I think it applies to my issue.

I am trying to install Jekyll locally as per the official instructions. It fails when trying to build/install commonmarker:

Installing commonmarker 0.17.9 with native extensions

The issue is that ruby.h is present on my machine (this is Fedora 26), albeit in a different location: /usr/include/ruby.h

I have a workaround in that I just symlink /usr/share/include/ruby.h to that location but I am not sure what is the status of Jekyll support via Github on the various distros. Is that an expected error (I am a newbie for Ruby-related things)?

stevokk commented Aug 9, 2018

I had the same above issue but it turned out I did need to install the ruby headers

sudo apt-get install ruby-all-dev

Link to solutions for other distros: StackOverflow Answer

Mine also needed zlib, so:

sudo apt-get install zlib1g-dev

On a Mac, make sure that you have the commandline tools installed

You can’t perform that action at this time.
