You have forgotten to tell us which operating system you are using.
I see you are using rvm, usually that will install the dependencies for you. Did you install rvm using the recommended method
curl -L https://get.rvm.io | bash -s stable --rails
curl -L https://get.rvm.io | bash -s stable --rails

relevant bits of the one you are replying to. Thanks.
As I said previously mkmf.log is a log file produced by the make, but
it is unlikely to help. Did you see my previous message where I asked
you to copy/paste the full command and result of the command you are
using to install rails?

Please post your reply inline in the previous message as I have asked

Install gcc, it's obvious by just looking at which point mkmf cancels... Probably you will stumble over more missing development packages after that, but let's make one step after the other.

He said he had already done
sudo apt-get install build-essential
and that
rvm requirements
said that all is installed, so if gcc is not installed then it is a little strange.
@Prasanna what does

Sine you are using rvm you should not use sudo for install gems, otherwise it does not install to the correct place.
I don't know why you should need those options to install nokogiri. What happens if you just try that command without the sudo?
If that works can you now install rails using
gem install rails

Please when posting back results copy/paste the full results with the command you entered) rather than re-typing bits of it. Sometimes bits that you consider not relevant may be important.
Also if you could post your reply back inline in the previous message so that your answer follows the question that would make it easier to follow the thread. Thanks.

previous message when replying and insert your reply inline within or
after the previous message so that it makes it easier to follow the
thread. I offer support on a number of lists and anything you can do
to make life easier for me will make it more likely that I will try to
help. Thanks.
Those look a little odd, as I have just installed on a 14.04 system
using rvm in a similar way to that in the tutorial you linked to and I
have ended up with ruby 2.2.1 (not 2.2.3) and gem 2.4.6 (not 2.4.8).
I don't know how you achieved that but it should not really matter.
However, all else having failed I think the only option is to use the
sledgehammer. I suggest you entirely remove rvm by
rm -rf ~/.rvm* ~/.gem/ ~/.bundle
Some of those may not exist so don't worry if it does not find them to delete.
Tell gem that we don't need to install the docs
echo 'gem: --no-rdoc --no-ri' > ~/.gemrc
Remove the Ubuntu version of gem if you have somehow installed it
sudo apt-get purge gem
Now install ruby and rails using rvm - Note never use sudo for
installing rails related stuff except for installing system libraries
and so on with apt-get. Otherwise you end up with things owned by
root and in the wrong folders.
You might have to put your password in if rvm needs to install any
system libraries or tools.
If any errors are thrown up then let us know.
You should already have added the line to load rvm on login onto the
end of .bashrc (as in the tutorial) so won't need to do that again.
logout and in again.
So now
rvm notes
rails -v
ruby -v
gem -v
should all work and show versions picked up from the .rvm folder in
your home directory.
Good luck

Those look a little odd, as I have just installed on a 14.04 system
using rvm in a similar way to that in the tutorial you linked to and I
have ended up with ruby 2.2.1 (not 2.2.3) and gem 2.4.6 (not 2.4.8).
I don't know how you achieved that but it should not really matter.
However, all else having failed I think the only option is to use the
sledgehammer. I suggest you entirely remove rvm by
rm -rf ~/.rvm* ~/.gem/ ~/.bundle
Some of those may not exist so don't worry if it does not find them to delete.
Tell gem that we don't need to install the docs
echo 'gem: --no-rdoc --no-ri' > ~/.gemrc
Remove the Ubuntu version of gem if you have somehow installed it
sudo apt-get purge gem
Now install ruby and rails using rvm - Note never use sudo for
installing rails related stuff except for installing system libraries
and so on with apt-get. Otherwise you end up with things owned by
root and in the wrong folders.
You might have to put your password in if rvm needs to install any
system libraries or tools.
If any errors are thrown up then let us know.
You should already have added the line to load rvm on login onto the
end of .bashrc (as in the tutorial) so won't need to do that again.
logout and in again.
So now
rvm notes
rails -v
ruby -v
gem -v
should all work and show versions picked up from the .rvm folder in
your home directory.
Good luck

I believe that has already been checked earlier in the thread.

Sorry, that answer was to the wrong mail, because of some flaws of Google's inbox mailclient.
In fact he only checked for libxml2, not for libxml2-dev as far as I understand ops answer.

It is a bit odd that he does not seem to be keeping his system up to

date (490 not upgraded), but I would think that is not likely to be an
issue. However:
@Prassanna unless you have a good reason you should keep your system
up to date using the software updater or by
sudo apt-get update && sudo apt-get dist-upgrade

I thought I would just chime in to say that I was (seemingly) having the same problem as described by Prasanna, and the "sledgehammer" approach described by Colin has solved it for me.
The first time I had tried installing rails, I was following the guide on https://gorails.com/setup/ubuntu/14.04 which prescribes calling,
The first time I had tried installing rails, I was following the guide on https://gorails.com/setup/ubuntu/14.04 which prescribes calling,
(without --rails), and calling "gem install rails" later. I'm not entirely sure why that borks things. My guess is that the script when called with --rails installs whatever magic package I was missing.
Cheers,

There are 2 problems:
- Even though installing ruby seems possible without source files (eg ruby.h) using eg rvm, ruby-install etc, subsequently installing rails as a gem requires these files. To avoid version mismatch with the versions from your os (package manager eg yum, yast, apt) its best to build ruby from source.
- nokogiri seems to have a bug. Installing rails as a ruby gem fails because of nokogiri wanting to bring in its own version of some dev fies (eg libxml2, libxslt). So you should install nokogiri separately first explicitly telling it not to use these files.
Download Ruby - build from source
Make sure in your os package manager (yum, yast, apt etc) that you install any prerequisites for building c fies eg
c compiler, make, etc
c compiler, make, etc
Additionally make sure the following are installed:
# libxml2-devel, libxslt-devel (for nokogiri)
# nodejs for runtime (server)
> cd ~/declan/Downloads/ruby-2.2.3
#create dir below first manually as user "declan" otherwise they will automatically get created belonging to root
> ./configure --prefix=/home/declan/dev/web_framework/rails/ruby/2.2.3/
> make
> sudo make install
Dowload and install "chruby" (https://github.com/postmodern/chruby)
# cd /home/declan/tmp/
wget -O chruby-0.3.9.tar.gz https://github.com/postmodern/chruby/archive/v0.3.9.tar.gz
tar -xzvf chruby-0.3.9.tar.gz
cd chruby-0.3.9/# install (to local dir .. dont need sudo)
# dont use setup.sh ...see below
> PREFIX=/home/declan/dev/web_framework/rails/chruby/0.3.9/ make install# !! dont do this since it adds a "chruby.h" file to /etc/profile.d/ which causes share/chruby/auto.sh to get run each system boot .. dont want this
# sudo /home/declan/tmp/chruby-0.3.9/scripts/setup.sh
# by default installs to "/usr/local/share/chruby/"
# edit chruby.sh to tell it about our custom ruby
# /home/declan/dev/web_framework/rails/chruby/0.3.9/share/chruby/chruby.sh
RUBIES+=("/home/declan/dev/web_framework/rails/ruby/2.2.3/")Now you have a clean locally installed version of rails (which is independent of any system version), which you can "activate via
> source /home/declan/dev/web_framework/rails/chruby/0.3.9/share/chruby/chruby.sh
> chruby 2.2.3
> ruby --version # 2.2.3
> gem install rubygems-update # update gem itself
One should be able to install rails as a gem now, but apparently nokogiri bringing its own versions of files like libxml2-devel, libxslt-devel causes error messages like youre having, so manually install it first explicitly telling it not to use these:
> gem install nokogiri -- --use-system-libraries Now install rails itself
> gem install rails
> rails --version
Rails 4.2.4

various versions of Ubuntu. I have found no need to do otherwise.
