Problem installing OpenERP server with buildout !

Question

I'm trying to deploy OpenERP with a buildout and my own piece of code. In fact I would like to build a complete deployement structure allowing me to use OpenERP with custom modules and patch.

First of all, before adding any personnal configuration, I was trying to create a buildout which will have the responsability to configure everything.

Buildout Configuration

My buildout.cfg configuration file look like this:

[buildout]
parts = eggs
versions=versions
newest = false
extensions = lovely.buildouthttp
unzip = true
find-links =
       http://download.gna.org/pychart/
[versions]

[eggs]
recipe = zc.recipe.egg
interpreter = python
eggs =
     Paste
     PasteScript
     PasteDeploy
     psycopg2
     PyChart
     pydot
     openerp-server

Configuration problem

But when trying to launch the buildout I have a couples of errors when trying to install the last needed egg (openerp-server)

On my side it just cannot find these modules, but they are in my eggs dir:

Error: python module psycopg2 (PostgreSQL module) is required
Error: python module libxslt (libxslt python bindings) is required
Error: python module pychart (pychart module) is required
Error: python module pydot (pydot module) is required
error: Setup script exited with 1
An error occured when trying to install openerp-server 5.0.0-3. Look above this message for any errors that were output by easy_install.
Is this possible that openerp hardcoded the his searching path somewhere ?

easy_install, a try

I decided to give a try to a clean virtualenv without any relation to the main site-package. But when using easy_install on openerp-server:

$ source openerp-python/bin/activate
$ easy_install openerp-server
...
  File "build/bdist.linux-i686/egg/pkg_resources.py", line 887, in extraction_error
pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  SandboxViolation: mkdir('/home/mlhamel/.python-eggs/psycopg2-2.0.13-py2.5-linux-x86_64.egg-tmp', 511) {}

I have always the error message however psyopg2 was installed or not on my machine

System's Configuration

• Ubuntu 9.10 x86-64
• Tried on Python 2.5/Python 2.6

Answer 1

I'm not familiar with buildout, but if I were going to try building an OpenERP installer, I'd start by looking at the nice one from Open Source Consulting. I've used it and been pretty happy with it.

Last time I checked, it doesn't set up the CRM e-mail gateway, but everything else I need was covered.

Answer 2

Ok I did this recently:

Don't try to install the egg, openerp is not really standard.

I used this buildout snippet:

# get the openerp-stuff as a distutils package
[openerp-server]
recipe = zerokspot.recipe.distutils
urls = http://www.openerp.com/download/stable/source/openerp-server-5.0.6.tar.gz

# similar idea for the web component
[openerp-web]
recipe = zc.recipe.egg:scripts
find-links  = http://www.openerp.com/download/stable/source/openerp-web-5.0.6.tar.gz

# add some symlinks so you can run it out of bin
[server-symlinks]
recipe = cns.recipe.symlink
symlink =  ${buildout:parts-directory}/openerp-server/bin/openerp-server = ${buildout:bin-directory}

The key however, is that I did not use virtualenv. You don't need to with buildout. Buildout + virtualenv is like Trojan + Ramses... one is enough, unless you are ... well one is enough. ;)

Now for this particular project I had followed the debian instructions and installed the required libs via aptitude. This was only because I was new to buildout at the time, one could just as easily install the psycopg2 module

Here are some excellent instructions. Ignore the django stuff if you don't need it. Dan Fairs is both a great writer and great buildout tutor. Check it out. Disclaimer: I am a disciple of the man, based on his buildout usage.

I am certain you do not want to use the egg on pypi, it never worked for me, openerp is not eggified, it's a distutils package.

Good luck!
