python3 -V

• Clean Linux OS
  
  • RedHat Linux / Rocky Linux (x86, ppc):

    su -
    dnf install -y python3-virtualenv python3-pip libpq-devel python3-devel
    

  • Debian: 11/12:

    su -
    apt install -y python3-venv
    

  Then create venv and install packages (as xormon):

  su - xormon     # make sure you make installation as xormon user
  cd ~/xormon-ng/server-nest/
  python3 -m venv venv
  venv/bin/python3 -m ensurepip --upgrade
  venv/bin/python3 -m pip install --upgrade pip
  venv/bin/python3 -m pip install -r microservices/analyzer/requirements/requirements.txt
  

  Once you get this error:

  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError(': Failed to establish a new connection: [Errno 101] Network is unreachable')': /simple/pip/
  

  Then try to avoid it by using internal proxy for Python packages installation

  venv/bin/python3 -m pip install --proxy http://<username>:<password>@<hostname>:<port> --upgrade pip
  venv/bin/python3 -m pip install --proxy http://<username>:<password>@<hostname>:<port> -r microservices/analyzer/requirements/requirements.txt 

  Restart XorMon:

  su - xormon 
  cd ~/xormon-ng
  ./xormon.sh stop
  ./xormon.sh start
