I am trying to install Hpricot but receive a build tools error from gem install. However I can install nokogiri gem can actually even figure I can’t type and fixed up my nokogirl entry. What do I need to do with hpricot. This is my install C:\rubygems-1.3.7\>gem install hpricot Building native extensions. This could take a while… ERROR: Error installing hpricot: ERROR: Failed to build gem native extension.

From the look of things, nokogiri installed successfully because a binary version of it was installed, thus avoiding the need to build it yourself. Apparently, there is no such binary build of hpricot for your platform (x86-mingw32). You need to install the DevKit associated with your Ruby installation. I believe you need this one: [http://github.com/downloads/oneclick/rubyinstaller/DevKit-4.5.0-20100819-1536-sfx.exe](http://github.com/downloads/oneclick/rubyinstaller/DevKit-4.5.0-20100819-1536-sfx.exe) Which I located via: > **[Downloads](https://rubyinstaller.org/downloads/)** > > The easy way to install Ruby on Windows This is a self-contained Windows-based installer that includes the Ruby language, an execution environment, important... > Installing ri documentation for nokogirl-1.0… > Installing RDoc documentation for nokogiri-1.4.3.1-x86-mingw32… > Installing RDoc documentation for nokogirl-1.0… > > C:\rubygems-1.3.7\> > > PS package management that picks up typo’s pretty narly Notice that there is actually a gem named nokogirl-1.0 installed along with nokogiri-1.4.3.1-x86-mingw32. My guess is that this particular typo is so common that someone made a dummy gem named nokogirl that simply depends upon the latest version of nokogiri. As part of its installation, nokogirl spits out that message about spelling. There is no magic here. 😉 -Jeremy ---
