I was having trouble getting jekyll to work with Ruby using cygwin on Windows 7 64-bit. I had better results using rubyinstaller + devkit. It would be really nice if I could use the rubyinstaller ruby inside of cygwin.
However, I get the following message when I try to execute rake.
$ rake page name="pages/about.md"
C:\Ruby193\bin\ruby.exe: No such file or directory -- /cygdrive/c/Ruby193/bin/rake (LoadError)
Is there any way to make rubyinstaller play nice with cygwin?
I just put a few of these in my .bash_profile:
alias gem=gem.bat
alias irb=irb.bat
alias rake=rake.bat
I never have any of the problems that Luis mentions.
The problem is cygwin converting all the scripts paths into cygwin paths (/cygdrive/...).
There is no solution for that since the invoke of the script is made from bash over rake scrip which invokes native Ruby.
There are a lot of other issues that cygwin will cause, and some are covered in RubyInstaller troubleshooting page
One alternative will be invoking rake.bat directly, skipping cygwin shebang detection.
But cygwin doesn't like batch files, which forces you to do cmd.exe /C rake.bat and that is a noisy command line.
The other alternative is install something like gem-exefy (gem install gem-exefy) and generate executables for your installed gems (rake.exe).
That way you invoke rake.exe instead of letting cygwin figure it out.
Another alternative is use MSYS Bash (included in DevKit) instead of cygwin, which plays way better than cygwin one, but you will still have issues with batch files.
As you can see, mixing non-native (cygwin) with native (RubyInstaller) have a lot of side-effects.

I have a Ruby gem with some scripts that are distributed as executables. On Linux, this means that they go on the PATH with the executable bit set when the gem is installed. But on Windows, I don't see that or anything equivalent. So, how can I make those scripts usable from the command line on Windows?
I noticed that the Gem::Installer package has a generate_windows_script command, which from the brief description appears to match what I'm trying to do. Can I use that to help here, and if so, how?
I'm using cygwin and install on them ruby, so cause I don't have much experiences with ruby I always get much error that those version is buggy to use fix, and many more... So my question is what version of ruby use with cygwin, that bypass all those problems?
I recommend installing the latest version from rubyinstaller.org as well as the devkit from the same page.
When you install it choose the option to add ruby to your path.
To get gem and the other batch files working correctly from cygwin you can add something like this to your .bash_profile:
ruby=`which ruby|perl -pe 's/\/[^\/]*$//'`
for i in `/bin/ls -1 $ruby/*.bat`
do
alias `basename "$i" .bat`=$i
done
If I want to work with Ruby in Vim, how can I add Ruby support to it?
First of all, you would need a Vim version that is compiled with Ruby support enabled. You achieve this with:
./configure <the rest of your options> --enable-rubyinterp
on a Linux system, for example.
The next steps would be installing the plugins of your choice, you probably want NERDTree, snipMate, vim-ruby-debugger....
There are a lot of plugins to make your life easier, but there is always the option to run arbitrary shell commands from within Vim, no extra plugin needed:
!ruby /path/to/script.rb
This will execute script.rb and print the shell output directly in Vim itself.
I would visit https://github.com/ and put "ruby vim" into search box. You should find plenty interesting add-ons for vim this way.
I never used ruby before, I just wanted to play around with HAML and SASS. I downloaded and installed Ruby's Windows installer (v1.9.1). Then, I clicked ruby.exe (the icon with a black window and a multicolored gem in the picture). Finally, I typed gem install haml and pressed Enter. But nothing happened. Am I doing something wrong?

You might need to put the path to Ruby into the PATH environment variable to do this, but this is how I do it:
I open up the command line utility. I then type ruby -S gem install <whatever>. This works like a charm.
I tried running Ruby and it shows a blank screen but lets me type code. When I press CTRL + C to cancel it then executes my code as well. Maybe you need to do that in the manner you are trying to right now. I just find it easier to just ruby -S <statement> instead. IronRuby gives me the REPL no problems though.
ruby.exe is the Ruby interpreter. If you want to type code into it, you obviously need to type Ruby code into it, not DOS command code.
The gem command is a DOS batch file (gem.bat). DOS batch files need to be run from the DOS command interpreter.
Installing Ruby using RubyInstaller, you get an shortcut in the Programs menu that let you open a command prompt with Ruby in the PATH
You use that in case you didn't select the option to add Ruby to the PATH.
Either case, the gem command you typed in should be entered at the command prompt, and not inside Ruby itself.
The latest build (rubyinstaller-1.9.2-p136.exe) had a problem. Rename the folder: c:\ruby192\lib\ruby\site_ruby or delete it altogether and this fixes "gem"
You can do "gem install compass" or if you're behind a proxy you might need to do.
gem install –http-proxy compass

I have not found a tab-completion script for RubyGem in Bash/Zsh.
Where can you get the tab-completion script for RubyGem in Bahs/Zsh?
Executable RubyGem commands are installed into /usr/bin or /usr/local/bin or whatever prefix Ruby is found under. Tab completion for commands should just work just like any other executable file in your PATH. If it's not working, verify that the directory RubyGems installs commands into is in your PATH.
There is currently no official method of doing tab completion for the parameters to any of these commands. If you need tab completion for a command installed via RubyGems, you'll need to write and/or install it yourself. See the Bash reference manual for details. There may already be a completion system for the specific command you're interested in, so be sure to google for it, but most commands installed via RubyGems do not have any auto-complete written for them.
Try:
http://github.com/oggy/ruby-bash-completion
To install it just copy gem file to /etc/bash_completion.d/
I had errors when trying to tab:
gem install
Because I didn't have some cache files in .gem directory. So I simply disabled it by editing gem file. I changed _gem_all_names function:
function _gem_all_names {
echo ""
}
That github-hosted bash completion is now part of Ubuntu Lucid Lynx. Sweet! If you apt-get install rubygems1.8 then the completion (commands and options!) should just work.
Unfortunately, as installed, it will only complete if it sees invocation of gem1.8, and not the more conventient gem. You can fix that manually if so inclined by extending the last line of /etc/bash_completion.d/gem1.8 to include gem as part of the complete name list. I'm sure there's a cleaner way, but that works.
This is (years) late, but as I was highly unsatisfied with the various completion scripts for gem that seem to be floating around the net, I decided to write my own based (somewhat) on the rather nice git completion script available in git-sh.
