I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link. I think it's an update to Ruby, but RVM is having trouble installing alternate versions of ruby as well.
Heres the full post:
$ sudo gem install jekyll
ERROR: Error installing jekyll:
ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h

Results logged to /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1/ext/gem_make.out
Does this mean I need to update the version of ruby I'm using via rvm?
Ubuntu
sudo apt-get install ruby-dev
gem install jekyll
Your problem is that either you system doesn't know where make is located at or you don't have it installed. The easiest way to fix this (and probably other issues you'll run into trying to get a ruby system up and running) is to install xcode.
You can get it at http://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12 for lion. Or it came on a CD with your computer for earlier versions.
If you're using Lion, please see comments below for a link to how to install developer tools on Lion.
I had the same error on Ubuntu and this helped me sort it out.
You must have ruby-dev installed
apt-get install ruby-dev
If you installed XCode and command line tools are still missing go to Terminal and
xcode-select --install
it will prompt you to install these tools. After that just follow SrBlanco´s answer. That solved the problem for me.
Good luck.
Need to install "make".
I am using Ubuntu 12.10.
sudo apt-get install make
Should work on any Debian based distro.
Note: this problem also occurs on newer MacBook Pro models that come with Mavericks pre-installed. I updated another post with my own solution that didn't involve Xcode at all. My system had the Xcode developer tools installed when I got the machine.
ERROR: Error installing jekyll: ERROR: Failed to build gem native extension
Install Xcode as mentioned if you don't have it installed already (https://developer.apple.com/xcode/). Plus you need the command line tools.
Open Xcode. Go to Preferences > Downloads > Install Command Line Tools
Installing command line tools for Xcode solved the problem for me on my Mac
xcode-select --install.
sudo apt-get install ruby-dev
sudo gem install jekyll
hope this will help, it works with me.
I had this same exact error when trying to install Jekyll, and the following steps from this link helped me. Just in case anyone else comes across this!
http://davidensinger.com/2013/03/installing-jekyll/
I was facing the same issue in my Fedora 22 setup. I had ruby installed but didn't have ruby-devel. Installing ruby-devel fixed the issue for me.
dnf install -y ruby-devel
For older systems:
yum install -y ruby-devel
I followed this on Ubuntu/Linux Mint
sudo apt install build-essential
sudo apt install ruby-dev
sudo gem install jekyll
An addendum: You can install XCode now from the App Store on Mountain Lion. The process is transparent and pretty fast.
I had the same problems with you.
I use Mac OS X 10.9 develop preview version, and I had installed gcc and Xcode.
But my Xcode version is 4.6.
Then I install the Xcode 5.0
After that I type sudo gem install jekyll in the terminal again. Then it works.
Wish it could help someone.
Installing Xcode and going to perferencs > downloads > install commandline tools WORKS!
Same problem on Debian, I had forgot to run this command:
~/.rvm/scripts/rvm
All these answers did NOT work for me.
If you're looking for a solution on ubuntu 14.04, do this:
sudo apt-get install ruby1.9.1-dev zlib1g-dev nodejs
sudo gem install jekyll -v 2.5.3
Unfortunately, nodejs is required because of a bug in Jekyll that enforces existence of runtime JS engine even though it doesn't need one.
For Ubuntu, this helped in my case:
apt-get install libffi-dev
A general advice is to just follow what is displayed as the reason for the error and hopefully you'll be provided with a log file in which the first line suggests which package should be installed, in my case:
To see why this extension failed to compile, please check the mkmf.log which can be found here:
/var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/ffi-1.9.21/mkmf.log
MacOS
my solution to this problem
install xcode
type xcode-select --install in the command line
type sudo gem install jekyll in the command line
PS: It is the combination of the two answers in this question.
You are missing the ruby-dev file , just go ahead and run this command - sudo apt-get install ruby-dev
Hope this helps!!
I had the same issue on my macOS(10.14.2), the reason may be:
Apparently with OSX el Capitan, there is a new security function that prevents you from modifying system files called Rootless.
My solution is using rvm:
install ruby on Mac OS X with RVM
gem install jekyll
On windows I have this issue
I actually installed the version rubyinstaller-devkit-2.6.3-1-x64 of ruby
I have removed the ruby completely and Installed the rubyinstaller-devkit-2.5.5-1-x64
and issued the following commands on powershell
gem install bundler
gem install jekyll
and this time no errors where found
I had this issue and of all things, the error was occurring because I hadn't agreed to some updated terms of service in xcode. Running the following did the trick for me. Go figure.
sudo xcodebuild -license accept
For me, I had to upgrade homebrew and install rbenv to the latest ruby version. After that, I followed the instruction at jekyll website. My OS is Catalina 2019, I couldn't install Xcode, which is not compatible yet!
You have to set the path in your .bash_profile to make sure that it initializes the rbenv when you restart your terminal.
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
then
$ rbenv version
2.2.3 (set by /Users/mislav/.rbenv/version)
$ rbenv shell
rbenv: no shell-specific version configured
hope that help!
Here is the (only?) reliable and simple way to install Jekyll on macOS
Install UTM
Install Ubuntu Server
Install Jekyll using Ubuntu instructions at https://jekyllrb.com/docs/installation/ubuntu/
Forward port 22 in the VM settings (22->localhost->22)
Use VS Code on the macOS host
Install Remote SSH
Connect to USER#localhost
Drag and drop the folder on Mac into VS Code (this transfers files to remote)
Enable port forwarding for 4000 (bottom bar on VS Code)
Work on your website
Right click on your website on the file explorer and click download
If you have not done these steps, you might be delighted by:
Ubuntu imports your public SSH key from GitHub
VS Code magically handles file transfer in and out
VS Code magically installs your VS Code extensions onto the remote server and allows file search on the remote host
I have just started learning Ruby on Rails and am having a little trouble getting the environment set up on a Macbook Air OS X version 10.9.3
I installed Ruby from rvm.io
I have:
Ruby 2.0.0p451
Rails 4.1.4
Git 1.7.4.4
XCode version 2003 (is this wrong?)
I used ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
but I get back Failed during: /usr/bin/sudo /usr/bin/xcode-select --install
I looked around and I have seen that people suggest Homebrew not be installed using sudo access, but it keeps asking for my password. What am I doing wrong here? Why does Homebrew refuse to install?
What is the exact version of XCode? 5.1.1? The failed command is to install XCode command line tool. Probably you can install that first before installing Ruby.
I get this error when I try to install Rails on my Mac OS Lion. I used the command -
$ sudo gem install rails
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h
Any steps I need to follow to install rails?
Thanks
Just avoid using the bundled ruby, which is 1.8 and it is really outdated. Install rvm which will provide an up-to-date ruby version and then everything will work seamlessly. This is the only thing you need to start:
$ curl -L https://get.rvm.io | bash -s stable --rails
You will need the gcc/g++ toolchain (Xcode) to build everything but you would have needed it in anycase to compile any native gem.
It looks like you're missing some header files - try reinstalling XCode and the developer tools. If you already downloaded XCode, make sure you've run the installer that it put into /Applications for you.
Like Jack says, using rvm will be a lot smoother.
The system Ruby in Mac OS is outdated, I recommend to you install RVM or Rbenv to manage your installed Rubies or to install new versions.
I'm stuck trying to install rails on my mac. I have OS X 10.6.8 and I have confirmed that I have Ruby, version 1.8.7
I ran sudo gem update and sudo gem update --system to get the latest versions of the software.
However, when I run sudo gem install rails I get this error:
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h
Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/json-1.6.3 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/json-1.6.3/ext/json/ext/parser/gem_make.out
If you have XCode 4 or later you will need to open it and go to Preferences -> Downloads -> Components and install the Command Line tools as they aren't installed by default. Couldn't install Rails until this happened.
Im using osx 10.10. You can download from the command-line
xcode-select --install
Not sure what it needs to compile, but OSX can't compile any native ruby extensions at all unless the Apple developer tools are installed. On 10.7 Lion you can download it free from the app store, or Download it here for 10.6: http://developer.apple.com/xcode/index.php
It may also be on your OSX install discs, though probably much more out of date.
Did you install the OS X developer tools? You'll need to do this to be able to build native extensions
Just a follow up ...
it may be that you are on a mac and rails cannot find the right compiler for c headers.
just install xcode from apps store / homebrew or go to terminal ...
$ xcode-select --install
complete the installation and agree on the licensing etc, then ...
$ sudo gem install rails
There are two possible reasons for the fail:
PRIMARY REASON: Missing Xcode Command Line Tools
Verifying Xcode Command Line Tools Installation manually:
Check for presence of
"/usr/include/iconv.h" (if absent=>Missing or improperly installed Xcode CLT)
Installing Xcode CLT:
Try running xcode-select --install on terminal and follow the instructions. If it fails, open Xcode.app, select from menu "Xcode" - "Open Developer Tool" - "More Developer Tools" to open the developer site, download the installer for your OS version and run it.
SECONDARY REASON(if 1. fails): Version issues
Try upgrading the ruby version using rbenv.
Hope it helps!
Steps to sort out this issue:
Follow these steps unless error is fixed.
Open terminal and run commands:
sudo xcode-select --install
sudo xcodebuild -license accept
Make sure you have installed only one Xcode and it is the latest one. If more than one version is installed then keep only the latest one with name in applications like Xcode.app
Open Xcode->preferences->locations then check if any command line tools are selected; if not then select
Install Ruby by:
brew install ruby
Install CocoaPods by
sudo gem install cocoapods
Try to install Ruby via RVM. I solved in this way
How to install ruby on Ubuntu with rvm
The Command line tools didn't solve this issue for me.
I upgraded ruby installation through rbenv to 2.2.0, made that the global default ruby installation, and this issue was fixed.
Switch Ruby to Homebrew version:
$ brew install ruby
$ brew link --overwrite ruby
$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
$ echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.bash_profile
$ echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.bash_profile
Just had a similar issue. I can confirm that installing the command line tools fixes it.

I had this problem on macOS Catalina 10.15.7, and it seems that Xcode 12.3's Ruby is a variant of 2.6, but my software needed 2.7.
I installed rvm and ran rvm install ruby-2.7, and now it works just fine 🎉
I'm running into issues trying to install Rails on OS X Lion using RVM.
So far, I have done the following:
Installed Mac OS X Lion Version 10.7 (Build 11A459e).
Installed XCode 4.1 Developer Preview 5.
Installed RVM.
Installed a 1.8.7 version of Ruby via RVM using the command rvm install 1.8.7. Note: I need to be using 1.8.7 and not 1.9.2.
Switched to the 1.8.7 version of Ruby using the command rvm 1.8.7.
Created a new gemset using the command rvm gemset create rails3.
Switched to the new gemset using the command rvm use 1.8.7#rails3.
To install Rails I ran the command gem install rails but I got the following error:
/Users/m/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
The same error happens when trying to run any gem command so I don't think it's really a problem with Rails.
Judging by the links below, I don't seem to be the only person having this issue:
http://twitter.com/#!/pingles/status/66261101351927809
and https://github.com/carlhuda/bundler/issues/1058
Fixed it!
The answer was actually on one of the links I posted above. Before installing a version of ruby (rvm install 1.8.7) I needed to run "export CC=/usr/bin/gcc-4.2". With that in place, everything ran smoothly.
If you don't want to have CC permanently exported, you can do CC=/usr/bin/gcc-4.2 rvm install 1.8.7
If you have already installed ruby 1.8.7. Just do CC=/usr/bin/gcc-4.2 rvm reinstall 1.8.7
If you have installed Xcode 4.2, it actually doesn't install non-LLVM gcc anymore, so you have to add it. For some reason downgrading to 4.1 after you've installed 4.2 doesn't work correctly (at least it didn't for me and others have had similar issues).
After quite a bit of thrashing, this is what finally worked for me:
Install Xcode 4.2 from App Store
Install darwin gcc using the OSX gcc installer
Install REE making sure you remove any vestiges of previous attempts:
Close any open terminal windows, open a fresh one and
rvm remove ree
export CC=/usr/bin/gcc-4.2
rvm install ree
This worked for me with rvm 1.8.6, OS X 10.7.2 and gcc-4.2 version 4.2.1 (Apple build 5666).
If you have already installed Xcode 4.1, resist the urge to upgrade to 4.2 and you should be okay.
If that still doesn't work add --force.
So this becomes:
CC=/usr/bin/gcc-4.2 rvm install ruby-1.8.7 --force
Make sure that you remove 1.8.7 if you already installed it before using "export CC=/usr/bin/gcc-4.2" by doing "rvm remove 1.8.7"
I had the same issue on my system. I installed the Xcode command line tools from Apple which ships with LLVM compiler and without an LLVM free one.
Ruby 1.8.7 won't work with an LLVM compiler not even with CC=clang, so installing an LLVM free gcc solves the problem.
There are multiple options listed here:
https://github.com/mxcl/homebrew/wiki/Custom-GCC-and-cross-compilers
Long story short, install GCC v4.2 with Homebrew:
brew install https://raw.github.com/Homebrew/homebrew-dupes/master/apple-gcc42.rb
and then install ruby 1.8.7:
CC=gcc-4.2 rvm install 1.8.7
Instead of "export CC=/usr/bin/gcc-4.2" do "export CC=gcc" (xCode 4.2.x should be installed).
Check which version of gcc you have like this:
ls -Al `which gcc-4.2`
I followed the instructions here:
http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion
brew update
brew tap homebrew/dupes
brew install apple-gcc42
Then reinstall:
Check again what your path to gcc is (to use for CC=):
ls -Al `which gcc-4.2`
(optional) You can set this in your .bashrc for example:
export CC=/usr/bin/gcc-4.2
(optional) remove any old version of ruby
rvm remove 1.8.7
Then:
CC=/usr/local/bin/gcc-4.2 rvm --verify-downloads 1 reinstall 1.8.7-p357 --without-tcl --without-tk
or if you have set CC in your profile
rvm --verify-downloads 1 reinstall 1.8.7-p357 --without-tcl --without-tk
Note the flags on the rvm install. I had trouble verifying the checksum on the ftp server and some problems with tck and what not. You may be able to omit those flags.
Also: you might need to remove an old version of your gemset:
rvm gemset delete <gemset>
Then
gem install bundler
bundle install
Hope this helps.
Using macport and ruby-1.9.x version.
I did successfully install rails with ruby gem.
I have same problem only for arch x86_64, when I comment line in my ~/.rvmrc
rvm_archflags="-arch x86_64"
Open a new terminal and tried to install ruby-1.8.7 again
rvm install 1.8.7
It was successful.
If you're using RVM in a development workflow, I added a fix in an .rvmrc file for OS X Lion.
https://gist.github.com/1112962
(updated file name)
This is not related to RVM, but if what you are looking for is a local development environment for Lion you may want to give a try to RubyStack It is a free, open source all-in-one installer for Apache, MySQL, Ruby, Rails, etc. It does not require compilation and it is self-contained so if you do not like it you can simply remove the installation directory and you are done. Disclaimer: I'm one of the RubyStack developers :)
CC=/usr/bin/gcc-4.2 rvm install 1.8.7 did not work for me, I used CC=/usr/bin/gcc rvm install 1.8.7 and it did (checking with "which gcc")
Even with all the other suggestions on this page I was still getting segfaults and getting frustrated, so I said "screw it!" and use the system-provided Ruby 1.8.7:
rvm use system
You need to use sudo for installing gems, but still waay less headache.
My solution was to override the /usr/bin/gcc symlink in the terminal. Here's how I did it:
https://plus.google.com/101970693023462019144/posts/eYVLvMCqTmc
This not only fixed my RVM installation, but also made sure that installing gems with native extensions (like rmagick) work.
