Installing Python with python-build

2019-01-30 17:08:00 +0000

Install pyenv. We’re not going to use it as-is, but it includes the python-build script that we will use:

mkdir -p ~/.direnv/
cd ~/.direnv/
wget -O pyenv-1.2.11.tar.gz \

tar -xzvf pyenv-1.2.11.tar.gz
ln -s pyenv-1.2.11 pyenv

mkdir -p ~/.direnv/bin/
ln -s ~/.direnv/pyenv/plugins/python-build/bin/python-build ~/.direnv/bin/

Then install your chosen Python version:

~/.direnv/bin/python-build 2.7.15 ~/.pyenv/pythons/2.7.15

To get a list of available Python definitions, use:

~/.direnv/bin/python-build --definitions

To update the list of Python definitions, you need to download and install a newer copy of pyenv. Just follow the instructions above, changing the version number.
