Trying to configure PATH variables for CLI measure testing

I am currently trying to set up the command line interface for for measure testing. I modified the PATH variable to point to the OpenStudio version of ruby to use.

I also tried putting a .rb file in the site_ruby file Path and overall I am getting an error of "Cannot load such file" -- openstudio.so (LoadError).

I am using OpenStudio version 2.5.1, and have the latest install of ruby 2.4

ruby files are executable from the directory with a hello-world that I tested, so I am not sure why it cannot load the openstudio.so file or that its not finding it. They are in the same directory.

UPDATE: downgraded my Ruby to 2.2.4 to see if that would fix the issue, no luck. Still getting an error "LoadError: cannot load such file -- openstudio.so"

Thank you! this is a new source I have not seen before. I completed all of the steps however when trying to install the gem bundler, and the json. both returned:

ERROR: Could not find a valid gem 'json' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

Make sure you have the correct ssl certificates installed: https://guides.rubygems.org/ssl-certi...

In particular this section: https://bundler.io/v1.16/guides/rubyg...

Also, I don't think you need bundler just for the CLI, though you may need it if you want to use 'openstudio-standards'. Try require 'openstudio' in ruby after you've set your path environment variable.

thank you for your help, After setting the new path to the new installation of ruby, with the openstudio.rb included in the site_ruby and the correct reference of openstudio-2.5.1 when I require 'openstudio' it is still telling me that it cannot load the .so file.

the Error being thrown appears to be coming from the kernel_require.rb file in ruby on line 54.

I am running windows 10, the solution to the problem was that I did not have the 64 bit version of ruby to match the 64 bit Open Studio.

Thanks again for the support!
