Looking at the OpenStudio compatibility matrix I have Ruby 2.7 installed locally. ( which is the correct version for my install) Currently using 3.5.1 (SDK) and 1.5 of the OS Application.

A Windows command prompt successfully can run any basic .rb script and I have some system variables set-up . I Have RUBYLIB that points to the openstudio.rb file located in D:\openstudioapplication-1.5.0\Ruby\openstudio.rb.

I am initially trying to run ruby test scripts from some of the pre-existing scripts. If I Run Ruby from a cmd prompt and go to this folder

C:\Users\xxx\OpenStudio\Measures\FindAndReplaceInAllThermalZoneNames\tests and run the .rb file eg Ruby find_and_replace_in_all_thermal_zone_names_test.rb all appear ok . Which suggests I have the basics setup ok. image description .

However If I try and run any of the other local test scripts, it generally throws an identical error See second screen shot image description

This error is common to most scripts.

I'm sure its a simple set-up or pathing issue. But why one script would run but no others is odd. Any pointers ?

You should be able to run the tests using the openstudio CLI rather than calling ruby directly. The openstudio CLI has ruby embedded inside it along with many of the gems (in this case, the openstudio-extension gem) that you need.

So try:

C:\openstudio-3.6.1\bin\openstudio.exe change_building_location_test.rb

Thanks. I will try to load the Gem file/extension and see how I get on. As am planning on writing and perhaps modifying some of the existing measures. I'm fairly comfy with C# but not really with Ruby. But will use the CMD line if I don't have any luck getting Ruby setup.

BTW Just tried running 2-3 tests directly from CMD line from the SDK 3.5, and they all ran perfectly. So now just need to get my Ruby Environment sorted.

This may or may not be useful for you: a Gist on setting up WSL2/Ubuntu/Ruby/OpenStudio.

An update to my original question: I have Ruby 2.7.2 Installed and can run any of the Test scripts in the measures Github repo (openstudio-common-measures-gem-develop). Which is fine, I can also run any test from the OpenStudio CLI.

The ruby version seems critical, and has to be as per the OpenStudio version compatibility matrix in order for any of the measures to be run in an IDE.

However most IDE tools like VScode etc all assume ruby 3.x is installed.

Most of the debuggers and extensions for VScode (rdbg, lsp etc) wont work with Ruby 2.x.

IF you install a newer version of Ruby , then all of the OS measures scripts wont run as they fail the initial version checks.

Are there any plans to update OpenStudio to run on a newer version of Ruby. As it would be great to be able to take an existing measures script and run it in debug mode line by line?
