AttributeError: 'ReadonlyTransportDecorator' with 'bzr serve'

[Parth Malwankar]

I recently installed ubuntu 9.10 and get the following exception with 'bzr serve --http'.

[trunk]% bzr serve --http

Have you tried running Loggerhead's trunk branch (lp:loggerhead)? IIRC,
that's what revision 388 fixed.

[Parth Malwankar (parthm)]

In order to run the trunk, I uninstalled existing loggerhead (which was installed from packages) and did 'bzr branch lp:loggerhead' in .bazaar/plugins.
I can't seem to get this to work.

[trunk]% bzr serve --http
bzr: ERROR: No module named loggerhead.apps.branch
You may need to install this Python library separately.
[trunk]%

[Matt Nordhoff (mnordhoff)]

Crap. That's bug #385281, and I'm not sure how to work around it.

Well, you could install the trunk Loggerhead globally (e.g. at
/usr/local/lib/python2.x/site-packages/loggerhead).

[Parth Malwankar (parthm)]

I tried the following three but continue to get the 'No module named loggerhead.apps.branch' error.
