title: Ruby LoadError: cannot load such file -- tk
body: <p>I am trying to use tk in Ruby in Windows 10. I have installed ActiveTcl and Ruby 2.4 from <a href="https://rubyinstaller.org/downloads/" rel="nofollow noreferrer">https://rubyinstaller.org/downloads/</a>. I am getting error as:</p>
  
  <pre><code>F:/Utilities/Ruby24-x64/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- tk (LoadError)
      from F:/Utilities/Ruby24-x64/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
  </code></pre>
  
  <p>Also checked the same from irb command prompt but got following error :</p>
  
  <pre><code>F:/Utilities/Ruby24-x64/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- tk (LoadError)
      from F:/Utilities/Ruby24-x64/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
  </code></pre>
  
  <p>Could you advise me on how to solve this problem?</p>
