I am trying to install LBT for Rhino 8 WIP on Windows 10.0.19041.3086.

I get a lot of “fatal errors” from the LBInstall component:

It claims the installation was successful but I can’t find Ladybug Tools among the GH libraries. What is going on?

Running the commands in cmd instead e.g. ./python -m pip install lbt-dragonfly==0.9.408 works fine so it must be an issue with the communication between the GH script and the Python executable.

Yes Installer Fails on V8 even when Choosing .NetFramework over .NetCore in the setDotnetRuntime.
My way of making it work is to install LBT using V7 and that should work once you launch it in v8.

“OLD” on icon means what ?

5

Delete the folder %homepath%.rhinocode\py39-rh8
Restart Rhino
Try Reinstall

OLD is the old python scripting component that has been updated in V8.

I just wanted to say thanks for answering everyone’s questions here, @tay.0 . That solution definitely works for now, though it completely resets the python environment of Rhino 8 to the “factory default” meaning it’s really only a temporary workaround.

I’m planning to push a new installer to Food4Rhino by the end of this week, which will be fully compatible with Rhino 8 (no more old tags and none of these issues with Rhino 8’s new Python environment variables causing fatal errors).

I just have a few more issues to fix to get all of the components working. I’ll post back here once it’s all on Food4Rhino.

Thank you Chris for everything!

FYI, there is now a release on Food4Rhino that works in Rhino 8:

The latest pollination Rhino/Grasshopper installers are also compatible with Rhino 8.
