Fetching a syntax_wiki post from HIVE - https://www.completenoobs.com/noobs/Fetch_Posts_From_HIVE_Blockchain

Container Setup

create container
lxc launch ubuntu:24.04 hive
Login to container
lxc exec hive bash
switch to user ubuntu
su - ubuntu

===Update System and Install Dependencies===

Update package lists
sudo apt update && sudo apt upgrade -y
Install essential packages
sudo apt install -y python3 python3-pip python3-venv git build-essential
Install development libraries needed for compilation
sudo apt install -y libssl-dev libffi-dev python3-dev
Verify Python installation
python3 --version

pip3 --version

===Create Virtual Environment (Recommended) ===

Create a virtual environment
python3 -m venv hive_beem_env
Activate the virtual environment
source hive_beem_env/bin/activate
Verify you're in the virtual environment (should show the path)

(hive_beem_env) ubuntu@hive:~$

===Install Beem===

Install beem from PyPI
NOTE: Beem is installed in Virtual Environment to avoid error: externally-managed-environment
pip install beem
