Install script error: cannot import name 'Feature' from 'setuptools'

[azylbertal]

Trying to install on a fresh Linux Mint 19.3 (virtual machine), with node 10.20.1, npm 6.14.4, pip 20.0.2, and git 2.17.1 (using a conda Python 3.7 environment as recommended). With the development branch cloned, running the install.py script results in the following error after some dependencies are successfully installed:

    ERROR: Command errored out with exit status 1:

Hi @azylbertal , thanks for reporting this. This seems related to some imported library using a setuptools deprecated api. Will look at the issue for the next releases, in the meantime you should be able to solve with pip3 install setuptools==45
