Hi ,

I am using ruby 1.8.6 and rails 2.3.5 in windows..

I have to install facebook_oauth gem, but i got below the error:

C:\Documents and Settings\Administrator>gem install facebook_oauth
-v=0.3.0
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing facebook_oauth:

c:/ruby/bin/ruby.exe extconf.rb

nmake
'nmake' is not recognized as an internal or external command,
operable program or batch file.


Gem files will remain installed in
c:/ruby/lib/ruby/gems/1.8/gems/json-1.6.4 for
 inspection.
Results logged to
