[Q]ImportError: No module named django.conf

[Linuxmaker]

Hi,

I installed Graphite on Debian 10 in addition to Icinga2. However, I only get a 503 error in the web browser. This is the reason for this

[Wed May 05 11:36:47.515673 2021] [wsgi:error] [pid 22706] mod_wsgi (pid=22706): Failed to exec Python script file '/opt/graphite/conf/graphite.wsgi'.

[Wed May 05 11:36:47.515794 2021] [wsgi:error] [pid 22706] ImportError: No module named django.conf

I proceeded as follows during the installation:

apt install python3-dev libffi-dev python3-cairo-dev python-scandir apache2 libapache2-mod-wsgi python3-pip gcc
pip3 install --upgrade pip
pip install --no-binary=:all: https ://github.com/graphite-project/whisper/tarball/master
pip install --no-binary=:all: https ://github.com/graphite-project/carbon/tarball/master
pip install --no-binary=:all: https ://github.com/graphite-project/graphite-web/tarball/master
ln -s /opt/graphite/lib/carbon-1.2.0-py3.7.egg-info /usr/lib/python3/dist-packages/
ln -s /opt/graphite/webapp/graphite_web-1.2.0-py3.7.egg-info /usr/lib/python3/dist-packages/
PYTHONPATH=/opt/graphite/webapp django-admin.py migrate --settings=graphite.settings --run-syncdb
PYTHONPATH=/opt/graphite/webapp django-admin.py collectstatic --noinput --settings=graphite.settings
PYTHONPATH=/opt/graphite/webapp django-admin.py check --settings=graphite.settings
chown www-data:root /opt/graphite/storage/
chown www-data:www-data /opt/graphite/storage/graphite.db
chown -Rf www-data:root /opt/graphite/storage/log
systemctl enable carbon-cache.service
systemctl start carbon-cache.service

How I can solve it, so django.conf will be founded?

Best regards Andreas

Hi @Linuxmaker ,

Did you install dependencies for graphite-web with pip3 install -r requirements.txt ?

[deniszh]

Also please show your webserver config for graphite-web

[Linuxmaker]

Did you install dependencies for graphite-web with pip3 install -r requirements.txt ?

I didn't use this command like that. I just ran the commands above. What should the content of the requirements.txt file be? I do not know this file.

[deniszh]

It's in the repo - https://github.com/graphite-project/graphite-web/blob/master/requirements.txt

[deniszh]

I also see another issue - you're installing e.g. libapache2-mod-wsgi which is for python2, then you set up everything for python3 which is looks fishy. So, please show your webserver config

[Linuxmaker]

Also please show your webserver config for graphite-web

That's my config file for the virtual host at Apache2: `<IfModule !wsgi_module.c> LoadModule wsgi_module modules/mod_wsgi.so

I also see another issue - you're installing e.g. libapache2-mod-wsgi which is for python2, then you set up everything for python3 which is looks fishy. So, please show your webserver config I think so right away. But existing HowTos for the installation of Graphite/Grafana in Icinga2 are partly different from each other. Do I need the Apache module libapache2-mod-wsgi if I should use "/opt/graphite/conf/graphite.wsgi"? Or which module I have to install for python3?

[Linuxmaker]

Now I have executed your command regarding the dependencies and I get these messages:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
graphite-web 1.2.0 requires django-tagging==0.4.3, but you have django-tagging 0.4.6 which is incompatible.

I would uninstall "django-tagging 0.4.6" and install manually "django-tagging==0.4.3", but I don't know how it runs at python.

@Linuxmaker : First, you need to decide which python are you going to run. Currently your Apache WSGI module running using Python 2, but half of your commands using Pythion 3. That's not going to work. If you want python2 you need to adapt commands above with python2
