Re: [jruby-user] Re: JRuby: gem install paths not working compared to Ruby

Hi,

I use JRuby in Cygwin without problem. I can get gem installed also. I did
not use rvm or any other manager. I haven´t installed Rails. If you want, I
might try to find my configurations for cygwin and Ruby. Some things I´ve
done:

   - Download jruby.tar from JRuby site
   - untar jruby and copy the directory to my cygwin directory
   - make a symbolic link (ln -s) from ‘jruby’ to ‘jruby-1.7.18/‘ (this
   will make it easier to upgrade later)
   - Download java jdk (from Oracle) and put it on my cygwin directory
   - add symbolic link from ‘jdk-7’ to above directory

In bash_profile

# Add access to java and and jruby before any other path
PATH=/jre7:/jdk-7:/jdk-7/bin:$PATH
PATH=~/bin:/jruby/bin:$PATH

I think this was all. After that, for developing my gems I have created a
config file to fix cygwin path. Does this help you in any way?

If you need my config.rb file let me know.

Hope this will be of any use!

Cheers…
