I found in google such errors, but no answers of this issue. And rails server can't start.

Install Ruby.In the Windows Explorer, double click on the rubyinstaller-1.9. 3-p194.exe file and follow the directions. By default, Ruby will be installed in the C:\Ruby193 folder. Check the boxes "Install Tcl/Tk support" and "Add Ruby executables to your PATH." Then click Install >> Finish.
Use `gem install -v` You may already be familiar with gem install , but if you add the -v flag, you can specify the version of the gem to install. Using -v you can specify an exact version or use version comparators.
Go to your file explorer and make sure the folder is gone. Now go to http://rubyinstaller.org/downloads/ and pick an older version. Follow that process just like the first time you installed ruby. Then go get nokogiri and whatever other gems you like and enjoy.
I had to upgrade RVM.
rvm get head rvm reload rvm install 1.9.3-p194 rvm use 1.9.3 If 1.9.3-p194 isn't the latest version (as of 06/07/2012), go to Ruby site to find out what is.
