I am trying to install and run Graphite on Ubuntu 12.10. To do it I followed this manual.

Unfortunately on the step:

Next, we will configure the Graphite database. Go to the Graphite webapp directory and run the database script:

cd /opt/graphite/webapp/graphite/

sudo python manage.py syncdb

I receive the following error:

Could not import graphite.local_settings, using defaults!

What can be the cause of the problem?

How can I fix it?

Today, I faced exactly the same issue using the same manual as you did. I guess the problem is related to the fact that some python dependencies are installed for 2.7 and some are installed for 3.2. So I decided to install 2.7 only and skip all packages for 3.2.

$ sudo apt-get install apache2 apache2-mpm-worker \
    apache2-utils apache2.2-bin apache2.2-common libapr1 libaprutil1 \
    libaprutil1-dbd-sqlite3 build-essential \
    python-dev \
    libapache2-mod-wsgi libaprutil1-ldap memcached \
    python-cairo-dev python-ldap python-memcache \
    python-pysqlite2 sqlite3 erlang-os-mon erlang-snmp rabbitmq-server \
    bzr expect libapache2-mod-python python-setuptools

$ sudo easy_install django django-tagging zope.interface twisted txamqp

When I use these two commands instead of the commands in the manual, I do not get the error you mention any more:

ImportError: cannot import name python_2_unicode_compatible
