Hey,

python -m pip install git+https://github.com/OpenSimulationInterface/open-simulation-interface
I get the followin error output. Any suggestions on how to fix this?

Hey, are you still having this problem?
For me this worked out:

I have added the PROTOC Path to the Windows Environment variables.
Then made the following change in the setup.py file:

the command "self.find_protoc" gives you only the folder and in my case i had to add the function call "\protoc.exe"

I hope this helps you out. :D

I think, it's not a bug, as the PROTOC is not a path-variable as the variable to the binary of the protoc-compiler.
In Windows, you schould set the variable to ...\protoc.exe.

The problem should be solved then, if the reference is set correcly.
