Error installing Urbanopt 0.14.0

[crossingchen]

I installed Urbanopt 0.14.0 on Mac using the installer downloaded from http://urbanopt-cli-installers.s3-website-us-west-2.amazonaws.com/ and followed the instructions.
Then I was able to create a project, generate the scenario files. But when I tried run the project using uo run --feature <path/to/GHP/featurefile.json> --scenario <path/to/SCENARIOFILE.csv>, I got an error saying some gem is missing and I need to run bundle install to install the missing gems.
When I ran bundle install, I got an error, rchardet-1.9.0 requires ruby version >= 3.0.0, which is incompatible with the current version, ruby 2.7.2p137.
It seems that rchardet-1.9.0 is not explicitly listed in Gemfile but is requested by the following block:
if allow_local && File.exist?('../openstudio-common-measures-gem')
gem 'openstudio-common-measures', path: '../../openstudio-common-measures-gem'
elsif allow_local
gem 'openstudio-common-measures', github: 'NREL/openstudio-common-measures-gem', branch: 'develop'
else
gem 'openstudio-common-measures', '~> 0.9.0'
end
Looks like this version of Urbanopt using ruby v2.7, but openstudio / rchardet-1.9.0 asks for > v3.0. How can I reconcile this?

Hi @crossingchen,
Looks like rchardet is a dependency of git, which is required by openstudio_measure_tester. v1.9.0 was just released 3 days ago and it unfortunately doesn't seem to have been locked down enough in git to avoid a ruby version issue.

Here is one thing to try: in your project gemfile, above the line that references openstudio-common-measures, add this line:
gem 'rchardet', '1.8.0'

Then you can rerun bundle install and hopefully that will fix the issue. Let me know how it goes and we can troubleshoot further if needed!

Thanks @kflemin! I added gem 'rchardet', '1.8.0' in the gemfile before openstudio-common-measures and it worked!
I was able to run through bundle install.

But after it's done, I ran uo -v and got an error
Traceback (most recent call last):

This command worked before I did the bundle install.
I tried reinstalled 0.14.0 from the installer, then redid bundle install, and this issue persisted. Not sure if this is related to the previous issue though.

@crossingchen can you make sure that you are running uo -v from a directory that DOES NOT have a gemfile in it? For example, don't run it from within your project directory. Let me know if that fixes it!

[kflemin]

@crossingchen did this solve your issues?

[crossingchen]

Thanks @kflemin for following up. I'm down with flu and will have an update next week.

@kflemin The issue was resolved if I run uo -v from a directory that does not have a gemfile. Thank you for your help!
