Installing new version of Python without root

Some time ago I was recommending to use Python virtual environment to install local version of Python packages. However this will not solve the issue of outdated version Python in the server your are working in. Here, pythonbrew may be help for you.

[bash]
# install pythonbrew to ~/.pythonbrew
curl -kL http://xrl.us/pythonbrewinstall | bash

# add to ~/.bashrc to automatically activate pythonbrew
[[ -s "$HOME/.pythonbrew/etc/bashrc" ]] && source "$HOME/.pythonbrew/etc/bashrc"

# open new terminal tab (Ctrl+Shift+T) or window (Ctrl+Shift+N)

# install python 2.7.10
pythonbrew install 2.7.10

# and enable the new version
pythonbrew switch 2.7.10

# from now on, you can enjoy the version of your choice and install dependencies
which python
#/home/…/.pythonbrew/pythons/Python-2.7.10/bin/python
python –version
#Python 2.7.10
which pip
#/home/…/.pythonbrew/pythons/Python-2.7.10/bin/pip
[/bash]
