error install dependencies: The BEZIER_INSTALL_PREFIX environment variable must be set.

[66696e656c696665]

When i install bezier more then 2020.1.14, i have error:
The BEZIER_INSTALL_PREFIX environment variable must be set.
and it only happens in venv, with a global installation everything is good.
I understand that this is an indirect problem, but maybe you have a solution?

Hello, I don't know if you still need this, but I set 'BEZIER_NO_EXTENSION=true' into my system vars and I manage to install it!
Hope it helps :)
