Hi Im following the simple mechanize tutorial on [http://ruby-doc.org/core/](http://ruby-doc.org/core/) i fire up irb then type and see the following irb(main):001:0\> require 'rubygems' =\> true irb(main):002:0\> require 'mechanize' LoadError: no such file to load -- mechanize         from C:/InstantRails\_Ver2/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_re quire.rb:27:in `gem\_original\_require'         from C:/InstantRails\_Ver2/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_re quire.rb:27:in `require'         from (irb):2 irb(main):003:0\> so i tried to install it via rubygems but... C:/InstantRails\_Ver2/ruby/bin/ruby.exe extconf.rb install mechanize --remote checking for stdio.h... no \*\*\* extconf.rb failed \*\*\* Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. not sure whats going. This is my ruby version ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32] and im using Instant Rails here is my gem list actionmailer (2.0.2, 1.3.6) actionpack (2.0.2, 1.13.6) actionwebservice (1.2.6) activerecord (2.0.2, 1.15.6) activeresource (2.0.2) activesupport (2.0.2, 1.4.4) capistrano (2.1.0) cgi\_multipart\_eof\_fix (2.5.0) cmdparse (2.0.2) fxri (0.3.6) fxruby (1.6.12) gem\_plugin (0.2.3) highline (1.4.0) hpricot (0.6) log4r (1.0.5) mongrel (1.1.2) mysql (2.7.3) needle (1.3.0) net-sftp (1.1.0) net-ssh (1.1.2) rails (1.2.6) rake (0.8.1, 0.8.0, 0.7.3) rubygems-update (1.0.1) sources (0.0.1) sqlite3-ruby (1.2.1) win32-api (1.0.4) win32-clipboard (0.4.3) win32-dir (0.3.2) win32-eventlog (0.4.6) win32-file (0.5.4) win32-file-stat (1.2.7) win32-process (0.5.3) win32-sapi (0.1.4) win32-sound (0.4.1) windows-api (0.2.0) windows-pr (0.7.2) anyone know how i can fix this? > **···** > > -- > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/). ---

Don't use extconf.rb to install gems. You need to use the "gem" command like so:   $ gem install mechanize Hope that helps! > **···** > > On Wed, Aug 20, 2008 at 12:28:44AM +0900, Adam Akhtar wrote: > > > Hi Im following the simple mechanize tutorial on > > [RDoc Documentation](http://ruby-doc.org/core/) > > i fire up irb > > then type and see the following > > > > irb(main):001:0\> require 'rubygems' > > =\> true > > irb(main):002:0\> require 'mechanize' > > LoadError: no such file to load -- mechanize > >         from > > C:/InstantRails\_Ver2/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_re > > quire.rb:27:in `gem\_original\_require' > >         from > > C:/InstantRails\_Ver2/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_re > > quire.rb:27:in `require' > >         from (irb):2 > > irb(main):003:0\> > > > > so i tried to install it via rubygems but... > > > > C:/InstantRails\_Ver2/ruby/bin/ruby.exe extconf.rb install mechanize > > --remote > > checking for stdio.h... no > > \*\*\* extconf.rb failed \*\*\* > > Could not create Makefile due to some reason, probably lack of > > necessary libraries and/or headers.

even when installed with gem , I encounter a problem ( if it's really a problem ) : if I step through my code ( ruby -rdebug code.rb ) , the debugger dies at the line 'require "mechanize"' ; I mention that I have included 'require "rubygems"' as the first line . However , if I set a breakpoint in my code , somewhere past that line , I can reach it . Could someone give me an explanation please ? > **···** > > -- > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/).
