pyenv-installer

Tools Shell

pyenv installer

This tool installs pyenv and friends. It is inspired by rbenv-installer.

Prerequisites

Git installed.
In general, compiling your own Python interpreter requires the installation of the
appropriate libraries and packages. The installation wiki provides a list of these for common
operating systems.

Installation / Update / Uninstallation

Once prerequisites have been installed correctly:

Install:

If you wish to install a specific release of Pyenv rather than the latest head, set the PYENV_GIT_TAG environment variable (e.g. export PYENV_GIT_TAG=v2.2.5).

curl https://pyenv.run | bash

pyenv.run redirects to the install script in this repository and the invocation above is equivalent to:

curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash

Restart your shell so the path changes take effect:

exec $SHELL

You can now begin using pyenv.
If you need, export USE_GIT_URI to use git:// instead of https:// for git clone.

Update: 

pyenv update

Uninstall:

pyenv is installed within $PYENV_ROOT
(default: ~/.pyenv). To uninstall, just remove it:

rm -fr ~/.pyenv

then remove these three lines from .bashrc:

export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv virtualenv-init -)"

and finally, restart your shell:

exec $SHELL

Using pyenv-installer on Travis CI

Travis itself uses pyenv and therefore PYENV_ROOT is set already. To make it work anyway the installation for pyenv-installer needs to look like this:

[...]
- unset PYENV_ROOT
- curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
- export PATH="$HOME/.pyenv/bin:$PATH"
- pyenv install 3.5.2

Development and testing

The project on github contains
a setup for vagrant to test the installer inside a vagrant managed virtual image.
If you don’t know vagrant yet: just install the latest
package, open a shell in
this project directory and say

vagrant up
vagrant ssh

Now you are inside the vagrant container and your prompt should like
something like vagrant@vagrant-ubuntu-trusty-64:~$
The project (this repository) is mapped into the vagrant image at
/vagrant

cd /vagrant
python setup.py install
echo 'export PATH="$HOME/.pyenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc
source ~/.bashrc

Pyenv should be installed and responding now.
