问题

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


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1 for inspection.
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?

回答1:

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.

回答2:

Ubuntu

sudo apt-get install ruby-dev
gem install jekyll

回答3:

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

回答4:

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.

回答5:

Need to install "make". I am using Ubuntu 12.10. sudo apt-get install make Should work on any Debian based distro.

回答6:

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

回答7:

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

回答8:

Installing command line tools for Xcode solved the problem for me on my Mac

xcode-select --install.

回答9:

sudo apt-get install ruby-dev
sudo gem install jekyll

hope this will help, it works with me.

回答10:

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!

回答11:

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

回答12:

I followed this on Ubuntu/Linux Mint

sudo apt install build-essential
sudo apt install ruby-dev
sudo gem install jekyll

回答13:

An addendum: You can install XCode now from the App Store on Mountain Lion. The process is transparent and pretty fast.

回答14:

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.

回答15:

Installing Xcode and going to perferencs > downloads > install commandline tools WORKS!

回答16:

Same problem on Debian, I had forgot to run this command:

~/.rvm/scripts/rvm

回答17:

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.

回答18:

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

回答19:

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.

回答20:

You are missing the ruby-dev file , just go ahead and run this command - sudo apt-get install ruby-dev

Hope this helps!!

回答21:

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

回答22:

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

回答23:

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

回答24:

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!
