Installing python3-setuptools-39.2.0-10.el7.noarch.rpm file by sudo rpm -i command on Red Hat 7.6 without internet access produced an error with messages
/usr/bin/python3 is needed by python3-setuptools~~ python(abi) = 3.6 is needed by python3-setuptools~~
The RHEL7.6 system came with Python 2.7 and I installed Python 3.9.2 from the official Python.org source tgz file.
In the /usr/bin directory, there are files named python, python2, and python2.7 but not python3.
I don't understand why it requires python '3.6'
