Installing Pyenv

This is a quick summary of how to get started with Pyenv and Python version/environment management. See the Pyenv Github for more details.

Other environment managers like conda will also work, if preferred.

Install dependencies:

sudo apt-get update; sudo apt-get install --no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev

Install Pyenv

curl https://pyenv.run | bash

Set up your ~/.bashrc

Check that the following lines below are included in the file. If not, paste them in. 

export PYENV_ROOT="$HOME/.pyenv"
command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

Activate your environment

This repo was tested using Python 3.10.8, however, Pyenv supports most Python versions (run pyenv install -l | grep '^ [0-9]' to see what is available to install). If another Python version is desired, replace 3.10.8 in the code below with your version.

If you have not previously installed Python with Pyenv, run 

pyenv install 3.10.8
Then, the following lines will create the environment and activate it for the current shell session. 
pyenv virtualenv 3.10.8 cbfpy
pyenv shell cbfpy

Tip

Use pyenv local cbfpy in the top-level cbfpy directory to automatically switch to this environment when working in this directory.
