Installation on Arch

[James Wood <la...@gmail.com>]

Hi everyone! I hope I'm posting to the right place.

Arch Linux's `python` is Python 3, but BH requires Python 2. What's the 
best way to make BH use `python2`, preferably without changing the 
Python version for the whole OS?

Sorry for taking so long to get round to this. Replacing `virtualenv` 
with `virtualenv2`, `pip` with `pip2` &c got everything working. Also, 
thanks to whoever added activate.fish.

Hey, good to see you here again!

https://wiki.archlinux.org/index.php/python gives a fair bit of 
information. In particular, once installed, when you want to run a 
script with python2 you will need to specify it because the default for 
the python command will be python3 (which is sensible as that way it 
shouldn't break Arch's scripts.)

If you want to use a virtualenv, you may find that you can create it 
with the -p python2 option but the wiki page above seems to suggest 
installing python2-virtualenv will give you a virtualenv2 which assumes 
python2 as the default.

Admittedly, none of this has been checked by me yet as I don't run Arch!

Cheers,
