Hello, all

I met a snag as the following:

root@ubuntu:/home/eduOSS# gem install github-pages
Building native extensions.  This could take a while...
ERROR:  Error installing github-pages:
    ERROR: Failed to build gem native extension.

    /usr/bin/ruby2.1 -r ./siteconf20150418-11838-636jct.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.1.0/gems/fast-stemmer-1.0.2 for inspection.
Results logged to /var/lib/gems/2.1.0/extensions/x86_64-linux/2.1.0/fast-stemmer-1.0.2/gem_make.out

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.

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

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

apt-get install ruby-dev

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

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.

@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.

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
/usr/bin/ruby2.3 -r ./siteconf20170220-10621-ejv836.rb extconf.rb
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!

Install command-t for vim
Here are some documents that came in handy:
  - I use vim 8 style of managing packages: https://shapeshed.com/vim-packages/
  - I had to use rvm use system to install command T in order that it would use
    the system ruby to install it wincent/command-t#214 (comment)
  - I had to install ruby2.3-dev github/pages-gem#133 (comment)
  - In order to install command t you have to do something either `rake make` or use
    `make clean; ruby extconf.rb && make`

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
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
current directory: /home/vincent/.gem/ruby/gems/commonmarker-0.17.9/ext/commonmarker

An error occurred while installing commonmarker (0.17.9), and Bundler cannot continue.
Make sure that gem install commonmarker -v '0.17.9' succeeds before bundling.
In Gemfile:
github-pages was resolved to 182, which depends on
jekyll-commonmark-ghpages was resolved to 0.1.5, which depends on
jekyll-commonmark was resolved to 1.2.0, which depends on
commonmarker

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)?

Thanks!

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
