Install Pyenv & Pipenv on AWS EC2 (Amazon Linux)

Installation

Install Dependencies

Pyenv builds Python versions from source and therefore requires all the necessary build dependencies.

sudo yum install gcc zlib-devel bzip2 bzip2-devel patch readline-devel sqlite sqlite-devel openssl-devel tk-devel libffi-devel

Install Git

You'll need git installed to be able to clone the repositories

sudo yum install git

Clone the Pyenv Git Repository

git clone https://github.com/pyenv/pyenv.git ~/.pyenv

Configure your '.bash_profile' file

echo ' ' >> ~/.bash_profile
echo '# Pyenv Configuration' >> ~/.bash_profile
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile

Reinitialise your Shell

source ~/.bash_profile

Testing pyenv

pyenv

Configuration

To prevent any existing system dependencies from breaking, it's a good idea to setup pyenv with versions of the current existing python installations.

Make a note of the version numbers currently installed for python2 and python3.

$ python -V
Python 2.7.5

$ python3 -V
Python 3.6.8

Install matching systrem python versions

pyenv install 2.7.5

pyenv install 3.6.8

Configure Global python versions

pyenv global 3.6.8 2.7.5

Check that the versions are associated correctly

$ pyenv versions
  system
* 2.7.5 (set by /home/norsey/.pyenv/version)
* 3.6.8 (set by /home/norsey/.pyenv/version)

Upgrade Pip

pip install --upgrade pip

Install Pipenv

pip install --user pipenv
