I am trying out the BEMOSS project on the tinker board but I am stuck at the below issue after the installation.
2018-04-29 16:44:14,441 () volttron.platform.vip.agent.subsystems.rpc ERROR: unhandled exception in JSON-RPC method 'start_agent':

This happens due to newer version of wheel. Reverting to wheel version 0.30 would resolve this issue. Refer to https://github.com/VOLTTRON/volttron/issues/1652
Please update to latest bootstrap.py from develop branch, and run
python bootstrap.py --force
this should create a new virtual environment folder with the right version of wheel.
