Instalando o Graphite no Ubuntu 12.10

Question

Estou tentando instalar e executar o Graphite no Ubuntu 12.10. Para fazer isso eu segui este manual .

Infelizmente no passo:

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

Eu recebo o seguinte erro:

Could not import graphite.local_settings, using defaults!
Could not import graphite.local_settings, using defaults!
Traceback (most recent call last):

    from django.utils.encoding import python_2_unicode_compatible
ImportError: cannot import name python_2_unicode_compatible

Qual pode ser a causa do problema?

Como posso corrigir isso?

    

Answer 1

Hoje, enfrentei exatamente o mesmo problema usando o mesmo manual que você. Eu acho que o problema está relacionado ao fato de que algumas dependências python estão instaladas para 2.7 e algumas estão instaladas para 3.2. Então eu decidi instalar o 2.7 e pular todos os pacotes para 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

Quando eu uso esses dois comandos em vez dos comandos no manual, não recebo mais o erro que você mencionou:

ImportError: cannot import name python_2_unicode_compatible
