<pre wrap="">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:

<pre wrap="">You need a newer version of the 'transaction' package. Unfortunately
the changelog at <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://pypi.python.org/pypi/transaction">http://pypi.python.org/pypi/transaction</a> doesn't say
which version added TransientError, but why not get the latest one?

<pre wrap="">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,

You mean in the global python ? For sure ! My goal was to make it
work in the virtualenv.<br>

<blockquote cite="mid:4FD99B7B.70804@gmx.de" type="cite"> Any

Python path is set in the global environment. In the virtualenv,
it was not set, but everything worked there anyway.<br>
</blockquote>
<br>
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 ? <br>
<br>
If you need it for system script, the shebang just have to use the
virtualenv python interpreter : #! /path/to/virtualenv/bin/python.<br>
<br>

<br>
Is there a way to uninstall the incompatible transaction version and
install the correct one? It would be very undesirable to use "#!
/path/to/virtualenv/bin/python" in every skript as we have a lot of
other imports, packages, modules... All this should be organized in
the same way. For our customers, it would be very annoying to keep
all the necessary steps in mind to make it work.<br>
Is it possible to fix this problem?<br>
<br>
