Hello guys,
i've been desperately trying to install ZODB3 via the following ways:
- easy_install ZODB3
- installation of Zope2
- manual installation of ZODB3, preceeded by installation of the
requested packages from pypi
I'm using Ubuntu and Python 2.6.
Whe trying to import ZODB, I'm still getting the following error:
python

[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

You need a newer version of the 'transaction' package. Unfortunately
the changelog athttp://pypi.python.org/pypi/transaction doesn't say
which version added TransientError, but why not get the latest one?
Can anybody help me, please?
The problem may be with a system wide installed version of transaction.
I would say, try in a virtualenv with no site packages :
$ virtualenv -p /usr/bin/python2.6 --no-site-packages myproject
$ cd myproject
$ . bin/activate
$ pip install ZODB3
Hope this helps,
Unfortunately, the error remains :(
You mean in the global python ? For sure ! My goal was to make it work
in the virtualenv.
[-- snip --]
Any further ideas?
Python path is set in the global environment. In the virtualenv, it
was not set, but everything worked there anyway.
You have a non compatible version of transaction installed globally, so
you won't run ZODB3 with your global environment. So Install / develop
your software in the isolated virtualenv. Is there a problem with that ?
If you need it for system script, the shebang just have to use the
virtualenv python interpreter : #! /path/to/virtualenv/bin/python.
Regards,
Alex
