Error When Running Default Workflow (UrbanOpt Version 1.0.1)

[grahamturk]

Hello! I just used the GUI installer for version 1.0.1 on a Mac (URBANoptCLI-0.14.0.28a3a24ed5-Darwin.dmg). I followed the steps for the default workflow on the Getting Started page. When I tried the uo run command, I get the following error:

stderr: Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
An error occurred while installing json (2.10.2), and Bundler cannot continue.

In Gemfile:
openstudio-calibration was resolved to 0.11.1, which depends on
openstudio-extension was resolved to 0.8.3, which depends on
bcl was resolved to 0.8.0, which depends on
openstudio_measure_tester was resolved to 0.4.0, which depends on
rubocop-checkstyle_formatter was resolved to 0.6.0, which depends on
rubocop was resolved to 1.50.0, which depends on
json
E, [2025-03-18T00:24:04.760936 #28894] ERROR -- : cannot load such file -- openstudio/common_measures

Is this a known error? I can share the mkmf.log if helpful.

@kflemin any ideas about this issue? Thanks in advance!

hi @grahamturk, the workaround for now is to go to your project's directory, locate the Gemfile file in that directory, open it and add the following line (near the top, under the "allow_local = ENV['FAVOR_LOCAL_GEMS']" line:

gem 'openstudio_measure_tester', github: 'NREL/OpenStudio-measure-tester-gem', branch: 'remove-json-gem'

Then rerun and it should get rid of that cannot load such file error. We are working on a more permanent fix for this issue.

Thank you @kflemin! That worked great.

Hi @kflemin I just redid these steps for a new case I'm working on and your fix is unfortunately no longer working. I changed the branch to 'develop' as I saw that the old branch was merged but am now getting the following error when running bundle update after adding that line to the Gemfile after creating the project.

Could not find compatible versions

Because openstudio-load-flexibility-measures >= 0.9.0 depends on
openstudio_measure_tester ~> 0.4.0
and openstudio_measure_tester >= 0.4.0, < 0.5.A could not be found in
https://github.com/NREL/OpenStudio-measure-tester-gem.git (at develop@9b573bf),
  openstudio-load-flexibility-measures >= 0.9.0 cannot be used.
So, because Gemfile depends on openstudio-load-flexibility-measures ~> 0.10.1,
  version solving has failed.

@grahamturk try to remove the line from the Gemfile completely and rerun. you can also make sure that the Gemfile.lock file is deleted.
