Hello, I am having an error in running dragonfly component (DF Run URBANopt) since updating LBT 1.9. The error is: 1. Solution exception:No URBANopt Gemfile was found in dragonfly_energy.config.folders.
This file must exist to run URBANopt.
I realized that gems are not present as shown in the screenshot.
How can I solve this problem as I re-installed Ladybug from food4rhino, and I also used LB versioner, but with no success.
It worked after installing ladybug using pollination grasshopper plugin.
Ahh, thank you for brining this up, @Mona92 .
I removed the honeybee-openstudio gem from the Food4Rhino installer.gh component because it’s not used anymore for OpenStudio translation now that we have the honeybee-openstudio Python package. But I forgot that the gem housed the URBANopt GemFile.
I should probably move the GemFile over to a different place like dragonfly-energy given that this is where everything else related to URBANopt simulation lives. But there are a few more files like this that need to be moved out of the honeybee-openstudio gem, making this a relatively big effort that should be fully addressed in LBT 1.10 instead of trying to do it all right now.
For now, let me put back the installation of the honeybee-openstudio gem in the Food4Rhino installer. Give me a few minutes and it the Food4Rhino installer should be fixed.
I added the honeybee-openstudio gem back into the installer.gh file:
… and I verified that this enables me to run URBANopt simulations. I also just updated the installer.gh file on the Food4Rhino download location so that installer is now fixed.
And you are correct that the Pollination single-click installer is also a way to ensure that you have all of the Ladybug Tools dependencies but now both the Pollination installer and the Food4Rhino installer are good to go.
Thanks so much for the quick fix and clarification!
