No gvm-cli or gmp command?

I had installed Greenbone Security Assistant Version 8.0+beta2.I can play GMP on IE.
I also installed gvm-tools,but no gvm-cli or gmp command in the systemOS,my systemOS version is CentOS Linux release 7.6.1810. Need your help please.

now gvm-cli can play,but errors reported like this:“File “/usr/bin/gvm-cli”, line 6, in
from pkg_resources import load_entry_point
ModuleNotFoundError: No module named ‘pkg_resources’”

First of all you are using an outdated pre release version of GVM. Please contact your package provider to get packages for the current version of GVM 10.

This error means Python (or more specific setuptools) couldn’t load gvm-tools from your Python environment. Most likely they are not installed correctly. If you are not familiar with installing Python software please take a look at the documentation of pip and installation of python packages. Otherwise follow our installation guide.
