@dweitz

The link to the reddit version of Paste (line 132) doesn't work anymore. Any other place to download it?

@spladug
Owner

The package hangs out here. That should've automatically been sourced by our setup.py. Did that not work?

@dweitz

It was timing out for me before for that one file and giving me 404 errors when I tried to download from a browser. Seems to be working now.

@cheapsteak

Ran into this error when I tried to install on a fresh ubuntu:

had to manually install lxml for it to work, with

sudo apt-get install python-lxml

@cheapsteak

The newest version of pycountry 0.14 which is installed by default doesn't seem to work with this script, threw this error

File '/usr/local/lib/python2.6/dist-packages/pycountry-0.14-py2.6.egg/pycountry/init.py', line 16 in
class Countries(pycountry.db.Database):
AttributeError: 'module' object has no attribute 'db'

installing 0.12.1 fixed it

easy_install "pycountry==0.12.1"

@Chiggins

For this to still work in (at least Ubuntu 10.10), you should change Cassandra's package name to include a previous version, since getting Reddit up in version 0.8 with the current configs wont work. "cassandra=0.7.2-0ubuntu4" would work.

@artlogic

pycountry has been updated and now works with the latest version

@rpicard

I ran into some problems using this on Ubuntu 11.04. I could be doing something wrong but I kept getting an error saying that aptitude was not a recognized command. I changed all of the references from aptitude to apt-get and it seems to have solved the problem. I just installed Ubuntu today to start playing with Reddit. I think the problem is that it doesn't come with aptitude installed (and it did in previous versions?).

See this gist for the modified version.
https://gist.github.com/1247021

@Chiggins

aptitude isn't installed by default in 11.04. I BELIEVE it's something of an upgrade to apt-get, but I can't fully confirm that.

@rpicard

I figured it was something like that. I ran into a few more errors after I got passed that and I realized I was getting in a little over my head with this. I'm going to stick with simple PHP scripts for now.

@Munksey

Aptitude is not installed by default. I just did a fresh install of 11.04. But, you can easily install it by running:
apt-get update
apt-get install aptitude

@andrewtuplin

I'm attempting to install on 11.1 (I removed the bit in the .sh that checks for version 11.04) and the install bails when it gets to the PPA:

root@ubuntu:/home/andrew/Downloads/gist922144-db8e2286a66ef18459cc356869df6d17e7b8f66a#

Any ideas on what's causing the script to bail?

@spladug
Owner

Yup, none of the packages in the PPA are compiled for Oneiric. There's a reason that version check is there :P

@andrewtuplin

Silly Me.

After reinstalling the correct version of Ubuntu, I'm bailing on the same error as Cheapsteak:

ImportError: No module named lxml.sax
make: *** [r2/public/static/button.js] Error 1

I've manually installed lxml with "sudo apt-get install python-lxml" but the script still dies at this line.

@ttanner

You need a newer version of Cython.

Note: we don't support Lucid any more and there're parts of the code that will not work on Python 2.6.
