    Hello,

    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.

    You're not providing the output or the error you're receiving, neither the version of Ruby, Bundler or RubyGems you have installed.

    We can't help you without that information.

    FYI, igraph gem depends on igraph library be installed. Please read the igraph gem README:

    http://igraph.rubyforge.org/igraph/

    Hello,

    You need to download igraph library, compile and install.

    I can't help you with that, specially since I have no knowledge of igraph library at all.

    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.

    If you're not familiar with library compilation, you can try read about it online.

    You can try asking this on specialized support groups like RailsInstaller or RubyInstaller:

    http://groups.google.com/group/railsinstaller
    http://groups.google.com/group/rubyinstaller

    Or you can ask the gem author to use tools like "rake-compiler" to provide native binaries for Windows and avoid these issues.
