Install pip
We first need to install pip, which we will use to install pythonbrew:
sudo apt-get install python-pip
Install pythonbrew
We now use pip to install pythonbrew
sudo pip install pythonbrew
Now we finish the install of pythonbrew as it instructs us:
pythonbrew_install
Then we make sure the pythonbrew files are loaded in our shell:
source "$HOME/.pythonbrew/etc/bashrc"
Install python 2.7
We can now instruct pythonbrew to install and compile python 2.7 for us:
pythonbrew install 2.7.3
This takes a while, it will go and compile python for you. When it it finished, we can tell our shell to use the freshly installed python:
pythonbrew use 2.7.3
Install python 3
To install python 3, we execute the following command. Note that this may take a while, because it compiles python:
pythonbrew install 3.2
To use this python, execute the following command:
pythonbrew use 3.2
Pythonbrew extra's
List all installed pythons:
pythonbrew list
List the available installation pythons:
pythonbrew list -k
Uninstall a python version (2.7.3 for this example):
pythonbrew uninstall 2.7.3
