I'm trying to learn Ruby. A task I'm trying to do is download a file from the web and save it locally.
I'm looking at
http://ruby.bastardsbook.com/chapters/io/ and trying to implement the solution in the "Exercise: Copy Wikipedia's front page to a file using block notation" section, but it's not working for me. The error message I get is:
/home/jhsu/.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- rest-client (LoadError)
from /home/jhsu/.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from test.rb:4:in `<main>'
What am I missing? Would another approach be better?
