Install devkit for pik-installed Rubies

Question

I've installed two rubies using pik, but I haven't installed any rubies outside of pik.

When I choose a Ruby using pik, and then try to set up devkit, no binaries are added to the generated config.yml file:

# This configuration file contains the absolute path locations of all
# installed Rubies to be enhanced to work with the DevKit. This config
# file is generated by the 'ruby dk.rb init' step and may be modified
# before running the 'ruby dk.rb install' step. To include any installed
# Rubies that were not automagically discovered, simply add a line below
# the triple hyphens with the absolute path to the Ruby root directory.
#
# Example:
#
# ---
# - C:/ruby19trunk
# - C:/ruby192dev
#
---

I tried adding the binaries within pik to the path, so that config.yml has

- C:/pik/rubies/ruby-1.9.2-p136
- C:/Users/agrimm/.pik/rubies/JRuby-170preview1

but I get

Do I need to install a ruby outside of pik in order to have devkit work?

Answer 1

I see that this question is old, but still unanswered. Your post mentions that you installed the ruby versions using pik. I don't know what pik does under the covers when installing ruby, but I've always used the Rubyinstallers directly. They have worked fine with pik, and I've installed DevKit with no problem. Note this bit from the DevKit docs:

ruby dk.rb init to generate the config.yml file to be used later in this Step. Your installed Rubies will be listed there (only those installed by a RubyInstaller package are detected at present).
