Can't Start Carbon - 12.04 - Python Error - ImportError: cannot import name daemonize

Question

I am really hoping someone can help me as I have spent at-least 15 hours trying to fix this problem. I have been given a task by a potential employer and my solution is to use graphite/carbon/collectd. I am trying to run and install carbon / graphite 0.9.12 but I simply can't get carbon to start. Every time I try and start carbon I end up with the following error. I am using a bash script to install to keep everything consistent.

I don't really know python at all so would appreciate any help you can provide.

/etc/rc0.d/K20carbon-cache -> ../init.d/carbon-cache
/etc/rc1.d/K20carbon-cache -> ../init.d/carbon-cache
/etc/rc6.d/K20carbon-cache -> ../init.d/carbon-cache
/etc/rc2.d/S20carbon-cache -> ../init.d/carbon-cache
/etc/rc3.d/S20carbon-cache -> ../init.d/carbon-cache
/etc/rc4.d/S20carbon-cache -> ../init.d/carbon-cache
/etc/rc5.d/S20carbon-cache -> ../init.d/carbon-cache


Traceback (most recent call last):
File "/opt/graphite/bin/carbon-cache.py", 
line 28, in from carbon.util import run_twistd_plugin
File        "/opt/graphite/lib/carbon/util.py", 
line 21, in from twisted.scripts._twistd_unix import daemonize 
ImportError: cannot import name daemonize

Thanks

Answer 1

pip install 'Twisted<12.0'

As you can see in the requirements.txt, the newer version of Twisted does not seems to play well with it

Works for me too. pip list | grep -i twist showed Twisted (14.0.0). When I did pip uninstall Twisted then installed Twisted<12.0, carbon was able to start. – Shipentine

Solved the exact same issue as above – Ubuntu 12.04 – Nightingale

pip install Twisted==13.0 – Vola

Answer 2

pip install daemonize

then I opened /opt/graphite/lib/carbon/util.py and changed

from twisted.scripts._twistd_unix import daemonize

to

import daemonize

Landa

it works!. I'm curious that will graphite will fix this or we will have to patch this manually everytime? Is there anyway to avoid manual update /opt/graphite/lib/carbon/util.py? – Reich

I will answer my own question, do: pip install Twisted==11.1.0 – Reich

Answer 3

I tried with pip install Twisted==11.1.0 but not got it downgrade my Twisted version. So, i renamed /usr/lib/python2.7/dist-packages/twisted/ to other name. After i install twisted pip install Twisted==11.1.0 and sudo ./bin/carbon-cache.py start works.

Answer 4

You can likely remove refences to daemonize from lib/carbon/util.py and then it seems to work with twisted 13.2.0. See carbon github commit 1d0bdc5c6ac331fdcb6f6c0f897507fcf833f616 from Nov 18 2013

Newest version of Twisted won't work.

Install version 13.0:

pip install http://twistedmatrix.com/Releases/Twisted/13.0/Twisted-13.0.0.tar.bz2
