Bug 304445 – dev-util/bzr-2.0.1 bzr: ERROR: No module named pyexpat

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Alex Cannon 2010-02-10 23:50:52 UTC]

bzr --no-plugins cat http://bazaar.launchpad.net/~launchpad-pqm/launchpad/devel/utilities/rocketfuel-setup > rocketfuel-setup

bzr: ERROR: No module named pyexpat
You may need to install this Python library separately

Could pyexpat please be added to portage? Thanks

Reproducible: Always

[Comment 1 Mark Lee 2010-02-11 01:27:56 UTC]

pyexpat is part of dev-lang/python by default (as USE=xml is turned on by default). Try re-emerging dev-lang/python with USE=xml enabled.

Note that when emerging Python with USE=-xml, it gives the following warning:

> You have configured Python without XML support.
> This is NOT a recommended configuration as you
> may face problems parsing any XML documents.

# emerge -pvD python

These are the packages that would be merged, in order:

I know things are a little dated, but in theory that shouldn't stop anything from working? And if minimum versions of python are required for it to work then that should be added to the dependancies, so that python gets updated automatically. The color of the "xml" use flag on python is red so I believe that means that python is already installed with xml enabled.

[Comment 3 Christian Faulhammer (RETIRED) 2010-02-11 17:44:24 UTC]

Normally the version should not be the problem.  Does a python upgrade work for you (without -D for emerge)?  Or what is the reason that you have so dated packages?
