PyF install issues

gistfile1.txt

I'm new to PyF... it looks like great framework to build workflow applications.

I'm running into an issue which I'm not quite sure how to solve before I give up on PyF...

Following the install guide, I've setup a virtualenv, and activated it... then:

     easy_install -UZ pyf[fullstack]

After some time easy_install seems to fail:

    Installed /home/lreg/env/pyf/lib/python2.7/site-packages/WebHelpers-1.3-py2.7.egg

    error: Installed distribution python-dateutil 2.0 conflicts with requirement python-dateutil>=1.5,<2.0dev


I've tried removing python-dateutil 2.0 (which seems to be a python 3 module, not python 2.7.2 which I'm running, and installed 1.5)... fine...

I restart easy_install again... to hit yet another dependency problem:

    error: Installed distribution WebOb 1.2b2 conflicts with requirement WebOb==1.0.8

So I remove WebOb 1.2.b2 and install 1.0.8, restart easy_install again... yet this fails again...

So pyf[fullstack] has a conflict with one of it's dependency's dependencies...

What is suggested to get around this so I can just try out PyF?

I too am stuck in this circular dependency...

I figured out how to get around this:

Here a re the steps I followed:

Install sqllite then:

virtualenv --no-site-packages ./env/pyf
source ./env/pyf/bin/activate
pip install pylons==1.0
pip install python-dateutil==1.5
pip install WebOb==1.0.8
easy_install -Z pyf.services
easy_install -Z pyf.components.producers.webextractor
easy_install -Z pyf.components.consumers.csvwriter
easy_install -Z pyf.components.consum ers.xmlwriter

Then followed the rest of the instructions here:

http://pyfproject.org/en/getting-started/configuring

Hmmm, I'm getting errors regarding the db:
(pyfenv)[indolering@web310 pyfenv]$ paster serve pyfservices.ini
Traceback (most recent call last):
File "/home/indolering/webapps/forge/pyfenv/bin/paster", line 8, in
load_entry_point('PasteScript==1.7.5', 'console_scripts', 'paster')()
...
File "/home/indolering/webapps/forge/pyfenv/lib/python2.6/site-packages/SQLAlchemy-0.6.8-py2.6.egg/sqlalchemy/engine/init.py", line 280, in engine_from_config
url = opts.pop('url')
KeyError: 'url'

Another dependency now is mercurial, so run pip install mercurial=2.2.3 before running the install

@jimklo: I would suggest WebOb==1.1.1 with the last pyf.services

Thank you very much for the precious infos ;)
