whitetimer · 2010-08-07 15:49:41

Hi All

Well i am new to Archlinux and have installed it as a Guest in VirtualBox so i can have a play around, before i decide to use it on my new Netbook (when it comes) .... Anyway i have just downloaded Python 3 and i want to set the PythonPath so what is the best way to do so ?

Many Thanks

I have no idea how to help you, but I'd recommend adding a '3' at the end of the topic's title.

You can find your current path with:

>>> import sys
>>> print sys.path

Then, you can add the following to your .bashrc, .zshrc, etc:

export PYTHONPATH=whatever you want

EDIT: In most cases when you install Python modules on Arch, they will be automatically added to the Python path. Setting your path manually is rarely needed to be done.

But you have Python 2 and 3 - won't they be stepping on each others' toes?

I don't know. I haven't dabbled too much in Python 3. I would assume that the Python development team would be smart enough to come up with a method of differentiating Python 2 and Python 3 locations in the same path.

@whitetimer:
I suspect with "downloaded" you mean you visited the webpage of python 3, downloaded their tarball or whatever and now want to install that..Am i right?

Python 3 is in the repo

community/python3 3.1.2-3 [installed]
Next generation of the python high-level scripting language

Just install it with pacman (pacman -S python3)(after you updated the lists, pacman -Sy) and that's that.

Here is some detail on how to handle different PYTHONPATHs for python 2 and 3:

I found that in addition to installing:

pacman -S tensorflow

I had to install:

pacman -S python-tensorflow

After this tensorflow works in Python as I expected.
