Error when trying to invoke the rails command via Cygwin on windows (installed via railsinstaller)

I have followed this tutorial for installing ruby on rails on windows. (the steps are explained in the video in the middle of the page)

If I run the rails command in a classic windows shell (windows + r > cmd > enter), it works fine. However, I would like to be able to invoke it in a cygwin shell. But if I do, for example: 

$> rails s # in cygwin

I have the following error:

C:\RailsInstaller\Ruby1.9.3\bin\ruby.exe: No such file or directory -- /cygdrive/c/RailsInstaller/Ruby1.9.3/bin/rails (LoadError)

I've looked into this folder:C:\RailsInstaller\Ruby1.9.3\bin\, and there is indeed no rails.exe, but only a rails and rails.bat file.

rails.bat looks like this:

@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
@"ruby.exe" "C:/Projects/railsinstaller/stage/Ruby1.9.3/bin/rails" %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO :EOF
:WinNT
@"ruby.exe" "%~dpn0" %*

I only know that cygwin looks for .exe files (for example, if you type cp, is it going to execute the cp.exe executable). I don't know how .bat files works.

So do you know how I can make cygwin able to invoke the rails command ?

I faced the same issue in cygwin but the "rails" command was working fine in windows cmd prompt. As a turn around Invoke the following command in cygwin,
alias rails='path_to_ruby_installed_directory/bin/rails.bat'

In your case,
alias rails ='C:/Projects/railsinstaller/stage/Ruby1.9.3/bin/rails.bat'

To make the alias permanent, Edit the .bashrc file in CYGWIN home directory and add the above alias in it.

Add this to your .bashrc or .zshrc to create alias for all appropriate .bat:

# cygwin
if [[ -n "$(which ruby 2>/dev/null)" ]]; then
  RUBY_BIN=$(cygpath -u $(ruby -e 'puts RbConfig::CONFIG["bindir"]') | tr -d '\r')
  for f in $(find ${RUBY_BIN} -regex ".*bat$"| xargs -n1 basename); do
    alias ${f%.bat}=${f}
  done
fi

As you've stated, the rails on windows is a ".bat" file. Just use the ".bat" extension in every command. It worked for me.

Try and see: "rails.bat -v" (in Cygwin)

I've been suffer from this problem for such a long time, and I've just found an workaround, In cygwin terminal:

ln -s path-of-you-rails-installer/RailsInstaller/Ruby1.9.3/bin/ruby.exe /bin/ruby ln -s path-of-you-rails-installer/RailsInstaller/Ruby1.9.3/bin/rails.bat /bin/rails

ps: the full path is gonna be something like: /cygdrive/d/RailsInstaller/Ruby1.9.3/bin/ruby.exe

and then rails can be invoked within cygwin.

It is not recommended to use Cygwin since everything is set up for use with Command Prompt. You may be able to get git-bash working but the Command Prompt included with RI is the supported method of using RailsInstaller. If you want to use Cygwin, I'd suggest not using RailsInstaller.
