For Vertex Workbench (Debian):

# Install deps
# from https://bgasparotto.com/install-pyenv-ubuntu-debian
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev

# Auto-installer
curl https://pyenv.run | bash

.bashrc not working on workbench? Added to .bash_profile:

conda deactivate

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

# Restart your shell for the changes to take effect.

# Load pyenv-virtualenv automatically by adding
# the following to ~/.bashrc:
eval "$(pyenv virtualenv-init -)"

# Add this for Poetry
export PATH=$HOME/.local/bin:$PATH

Installed pyenv-virtualenvwrapper plugin using git clone: https://github.com/pyenv/pyenv-virtualenvwrapper
