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
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!
Just for the record: there is a buildout recipe for OpenERP available in Pypi.
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.

i am currently working on a package and am confused with setuptools. This package contains many dependencies and with these dependencies, multiple scripts can be executed via cli.
E.G.
> main_pkg
> main_pkg_which_needs_dep1
> main_pkg_which_needs_dep2
> ...
It is not necessary to have all scripts available on a system. Only the relevant ones. So i thought that i could simply modify my setup.py as follows:
...
entry_points=dict(console_scripts=[
'main_pkg = main_pkg.main_pkg:main ',
'main_pkg_which_needs_dep1 = main_pkg.main_pkg:main_dep1 [dep1]',
...
]),
...
extras_require={
"dep1": ["psycopg"],
"dep2": ["apsw"],
"dep3": ["numpy"],
...
},
And assummed if someone executes pip install main_pkg, that only main_pkg would be available in CLI. (Therefore, if executing pip install main_pkg[dep1], then there would be main_pkg and main_pkg_which_needs_dep1 available in CLI)
However, executing pip install main_pkg also makes all other console_scripts available through CLI, failing if executing e.g. main_pkg_which_needs_dep1 due to missing dependencies.
Is this behaviour expected by setuptools?
From the documentation i am reading the following:
It is up to the installer to determine how to handle the situation where PDF was not indicated (e.g. omit the console script, provide a warning when attempting to load the entry point, assume the extras are present and let the implementation fail later).
Also, if looking here, the documentation mentions the following:
In this case, the hello-world script is only viable if the pretty-printer extra is indicated, and so a plugin host might exclude that entry point (i.e. not install a console script) if the relevant extra dependencies are not installed.
Am i understanding the documentation correctly, that the installer (plugin host? --> pip?) has to handle this case, which is currently not working?
Or do i have to further modify the setup.py to achieve such a behaviour?
Thanks in advance!
I ran into this same problem. Based on this thread: https://github.com/pypa/pip/issues/9726, it does not look like you can optionally install console scripts.
However, this comment: https://github.com/pypa/pip/issues/9726#issuecomment-826381705 proposes a solution that may help you. I'll copy-paste it below.
Have myscript with the extra [cli] depends on myscript-cli the package and myscript-cli depends on myscript but contains the entrypoint to the console_script in the main package.
If you install myscript[cli] it requires myscript-cli package which then gets installed and that contains the entrypoint you wanted. This makes myscript[cli] or myscript-cli install both packages, but permits a myscript install that will not require the -cli package and thus will not provide the entrypoint.
I would like to write and run a Mesos framework with Python, so I need mesos.native module.
On Ubuntu:
I can build mesos from source code. I tried to easy_install all the generated egg files but none of them made it possible for Python to import mesos.native.
I also tried to download the egg from http://downloads.mesosphere.io/master/ubuntu/14.04/mesos-0.20.1-py2.7-linux-x86_64.egg and easy_install it, which didn't work as well.
On Max OS:
Got some problem building the mesos source code because of the issue. So I am wondering whether there is an easy way to install the Python module without building the source code.
BTW, why don't they make the mesos.native pip-installable like mesos.interface?
Problem solved: https://github.com/RobinDong/mesos-python-examples/blob/master/calculate_pi/pi_run
I just need to set PYTHONPATH as that in the file and run python. Mesos.native can be successfully loaded.
I'm trying to install a python package from the private reportlab pypi server using zc.buildout.
When I install using the instructions provided on their own site, then it installs without problem. http://www.reportlab.com/reportlabplus/installation/
If however I install using zc.buildout, I keep getting Couldn't find distributions for 'rlextra'. I added their pypi repo to find-links, so I'm not sure what I'm missing.
My buildout config:
[buildout]
versions = versions
include-site-packages = false
extensions = mr.developer
unzip = true
find-links = https://[user]:[pass]#www.reportlab.com/pypi
parts =
python
django
compass-config
auto-checkout = *
eggs =
...
rlextra
...
... etc.
Edit: I should point out that I did in the end do a manual download of the package, and using it in my buildout as a develop package. Even though this solves the immediate issue, I would still like to know why my original setup is not working.
You are passing in the PyPI main link for the find-links URL, but find-links only works with the simple index style pages (which exist per package on PyPI).
For example, the beautifulsoup4 package has a simple index page at https://pypi.python.org/simple/beautifulsoup4/.
The ReportLab server also has simple pages; add the one for this package to your buildout:
find-links = https://[user]:[pass]#www.reportlab.com/pypi/simple/rlextra/
IIRC you can also add the top-level https://[user]:[pass]#www.reportlab.com/pypi/simple URL as a find-links, but being more specific saves on the URL round-trips.
I have downloaded setup exe from http://sourceforge.net/projects/gaphor. I am already having installation of Python2.7, PyGTK (Complete package). So when I start the install, I deselect Python2.5, PyGtk etc (as I already have python2.7). But as soon as I begin installation, I got the error:
PyGtkGUI can't be installed as Python not found on this system. PYPATH = No Registry key found.
NOTE:
I am able to proceed, actually i downloaded source code and build it and is working from there. However i would like to know the solution for the original problem reported.
you must add an environment variable
http://www.itechtalk.com/thread3595.html
and use official site wiki:

I'm trying to install the pyMySQL module for python so that I can setup Django (see this previous question).
I can't get easy_install.exe PyMySQL-0.3-py2.6.egg to run for the life of me. Every time I get the error easy_install.exe not recognized as an internal or external command... I've tried adding various directories to my system path including:
C:\Python27\Lib\site-packages\;
C:\Python27\Scripts\;
C:\Python27\Scripts\easy_install.exe
C:\Python27\Scripts\easy_install.exe PyMySQL-0.3-py2.6.egg
What am I missing that is keeping this from executing?(note I'm on windows 7)
You have to install setuptools first
[edit]
Uh,
C:\Users\Robus>easy_install
Yada yada, not found
C:\Python26\Scripts>easy_install
error: No urls, filenames, or requirements specified (see --help)
C:\Python26>
The next best thing I can think of is - do you, by any chance, have more than one version of python installed? In that case setuptools might have been installed somewhere else
