error: subprocess-exited-with-error

[SmartPycg]

Hi，I failed to build your project due to error: subprocess-exited-with-error

I used the following commands in python:3.7 docker：

pip install -r dev-requirements.txt
python setup.py install

Can you help me？

What are you trying to do? pip install cryptography is generally the correct way to install this package, not git cloning and installing with setup.py install.

In any event, please provide text (not a screenshot) of the complete output of running the installation.
