<p>help.rubygems.org is not a support group about gem installation,
even less on the usage of Bundler. Is a support site to deal with
specific issues of RubyGems website and service itself.</p>
<p>You're not providing the output or the error you're receiving,
neither the version of Ruby, Bundler or RubyGems you have
installed.</p>
<p>We can't help you without that information.</p>
<p>FYI, igraph gem depends on igraph library be installed. Please
read the igraph gem README:</p>

<p>You need to download igraph library, compile and install.</p>
<p>I can't help you with that, specially since I have no knowledge
of igraph library at all.</p>
<p>As instructed on igraph gem readme (which I provide you a link
to) there is a section mentioning how to install the gem once you
have igraph installed, which already provides a link to the library
website where you should be able to download it, compile it and
install it.</p>
<p>If you're not familiar with library compilation, you can try
read about it online.</p>
<p>You can try asking this on specialized support groups like
RailsInstaller or RubyInstaller:</p>
<p><a href=
"http://groups.google.com/group/railsinstaller">http://groups.google.com/group/railsinstaller</a><br>
<a href=
"http://groups.google.com/group/rubyinstaller">http://groups.google.com/group/rubyinstaller</a></p>
<p>Or you can ask the gem author to use tools like "rake-compiler"
to provide native binaries for Windows and avoid these issues.</p></div>Luis Lavena
