I am trying to set up a Python development environment on Centos7 , I am relatively new to both Linux and Python. I am following this guide to setup the environment but I am getting an error when I have to setup virtual environment.Using this guide:https://www.metachris.com/2016/03/how-to-install-qt56-pyqt5-virtualenv-python3/but when I run this to create virtualenv for PyQr5, I get this error:python3 -m venv ~/.venv/qtprojectError: Command '['/root/.venv/qtproject/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1I can see it created the directory structure, but I don't see any activate file to get the env activated.[root@cent7 qtproject]# lsbin  include  lib  lib64  pyvenv.cfgwhen I try to activate the env, it just seems to fail as there is no activate file or folder.[root@cent7 bin]# source activatebash: activate: No such file or directory
