Failed to build gem native extension when install RedCloth-4.2.9 install Linux

Question

I want to install Octopress in my computer. I try to do it like

When I run

bundle install

I got error message

An error occured while installing RedCloth (4.2.9), and Bundler cannot continue.
Make sure that `gem install RedCloth -v '4.2.9'` succeeds before bundling.

So, I run

sudo gem install RedCloth -v '4.2.9'

then, I got a error message again:

ERROR:  Error installing RedCloth:
ERROR: Failed to build gem native extension.

    /usr/bin/ruby1.9.1 extconf.rb
    /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from extconf.rb:1:in `<main>'

I hadn't learn any knowledge about ruby.

What GNU have you? Have you build `dev` package for Ruby. – Hauleth Aug 25 '12 at 09:18 — Hauleth, Aug 25 '12 at 09:18

My ubuntu 12.04 solution is install the ruby1.9.1-full version, that can resolve this issue.

sudo apt-get install ruby1.9.1-full

you can execute command:

sudo update-alternatives --config ruby

to select the altiernative ruby which you have installed. and then, execute below commands to finish the octopress deploy:

git clone https://github.com/erizhang/octopress.git octopress
cd octopress/
sudo gem install bundler
sudo gem install RedCloth -v '4.2.9'
bundle install
rake install

below commands you can find from octopress deploy guideline page:

rake setup_github_pages
sudo rake setup_github_pages
sudo rake generate
sudo rake deploy

Hope it's helpful for you, thanks

Works on Raspberry Pi, Thanks. – ahgood May 11 '13 at 18:26
This also just worked on a fresh Terminal.com Debian 7.0 (Wheezy) terminal. Hurray! (Just started playing with Terminal.com. Hurray!) – Jared Updike Nov 24 '14 at 18:26

I was installing Octopress too and got the same problem as yours. After checking the mkmf.log file I figured out that gcc-4.2 had not been found. I Even installed xcode with the command line tools. It worked when I made a symlink like this:

$ sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
$ bundle install

This worked for me, but only after I acquired gcc-4.2 in the first place. To do that: `brew tap homebrew/dupes && brew install apple-gcc42`. [Credit.](http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion) – Bad Request Oct 02 '12 at 02:54
This definitely saved me. Thanks! – kyletaylored Dec 19 '12 at 21:46

If apple-gcc42 is missing Install the Command Line Tools (Xcode 4.3). XCode -> Preferences -> Downloads, Click the Components button, and then click Install next to the "Command Line Tools". – Praveen Vijayan Dec 25 '12 at 07:37

I fixed this issue by running

sudo apt-get install ruby-dev

as described in this blog post.

This solved the problem for me on Linux Mint 17 (based on Ubuntu 14.04). – KajMagnus Aug 29 '14 at 07:59

You've probably upgraded to Mountain Lion and have not rebuilt your ruby-1.9.2 install yet with the new development packages.

rvm --force install 1.9.2
gem install bundle --no-ri --no-rdoc
bundle install

If you don't have the Mountain Lion dev packages installed correctly, use the ThoughtBot instructions.

For Ubuntu 14.04 simply do this:

sudo apt-get install ruby1.9.3

Should work for 13.10 and 13.04 too. (Not tested)

I'd do that as `install ruby1.9.3`. The space in there allows for some confusion. – Eric Anderson Jun 06 '14 at 20:01
@EricAnderson The space has been removed. Thank you. – Saugat Jun 07 '14 at 14:02

it apears you are not using rvm for managing your ruby installation. I think best would be to try rvm, here's a very good guide, you can stop without installing rails: ruby with rvm

Then simply

$gem install RedCloth

Unmanaged ruby gems are a pain, I try to avoid them.

None of the answers worked on my Ubuntu 14.04.1 LTS. Upgrade to ruby 2.0 fixed the problem for me:

sudo apt-get install ruby2.0 ruby2.0-dev
sudo ln -s /usr/bin/ruby2.0 /usr/bin/ruby
sudo ln -s /usr/bin/gem2.0 /usr/bin/gem
sudo gem install bundler

Make sure you also have the build-essential package installed. You can check using

dpkg -l | grep build-essential

or simply install it without checking

sudo apt-get install build-essential

For me on Ubuntu 14.04.1 LTS, after making sure build-essential is installed, the bundle install command works/builds fine also with Ruby 1.9.3.
