Setting up Linux for Python and this class¶
NOTE: this is from memory: no system to test on right now.
Getting The Tools¶
You probably already have python. Try:
$ python Python 2.7.8 (v2.7.8:ee879c0ffa11, Jun 29 2014, 21:07:35) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on linux
You can see what version you’ve got. If you don’t have 2.7.*, then you’ll need to go try to find a newer version – your distribution may have a package named something like:
$ apt-get install python2.7
Or yum install or ???
Every Linux box has a terminal emulator – find and use it.
git is likely to be there on your system already, but if not:
$apt-get install git
pip is the Python package installer.
Many python packages are also available directly from your distro – but you’ll get the latest and greatest if you use pip to install it instead.
To get pip, the first option is to use your system package manager, something like:
$apt-get install python-pip
If that doesn’t work, you can get it from:
download get-pip.py from that site, and run it with python:
$ python get-pip.py
It should download and install pip (and setuptools)
You can now use pip to install other packages.
One we are going to use in class is iPython:
$ pip install ipython
You should now be able to run iPython:
$ ipython Python 2.7.8 (v2.7.8:ee879c0ffa11, Jun 29 2014, 21:07:35) Type "copyright", "credits" or "license" for more information.
