Ruby and RubyDev under Chocolately on Windows

I have installer ruby 2.3.1 ruby.devkit 4.5.2.20120101 from the chocolately repostory on windows 10

then i have modified conf.yml and run:

PS C:\tools\DevKit> ruby dk.rb install --force
[WARN] Updating (with backup) existing gem override for 'C:/tools/ruby23'
[WARN] Updating (with backup) DevKit helper library for 'C:/tools/ruby23'

All seem to me ok, but when I try to update gems, some of them show the following errors:

PS C:\tools\DevKit> gem update

i realy can't understand what is happen, any idea?

The important part in the error messages is:

The compiler failed to generate an executable file. (RuntimeError) You have to install development tools first.

In order to install compiled gems, you need a compiler installed. For Windows, you can install the Ruby DeveloperKit.

While you have it installed apparently, it doesn't seem to be recognized. This can have one of various reasons, the most common being the devkit not matching your ruby version or issues with the %PATH.
