Getting "*** failed to import extension" errors after upgrading to 1.5.1

[Pavel Shevaev]

Folks, I have upgraded my mercurial installation to 1.5.1 version and
now hg can't find extensions.

I used to have mercurial installed by apt-get, first I removed it by
running "apt-get --purge remove mercurial" and then installed
mercurial from the source manually.

Looks like it can't find the directory with built-in extensions for
some reason. it's strange because it's definitely in PYTHONPATH: I
added "print sys.path" into /usr/local/bin/hg and now when running hg
it shows something like this:

['/usr/local/bin', ... '/usr/local/lib/python2.6/dist-packages']

... and /usr/local/lib/python2.6/dist-packages/hgext does contain the
required extension(fetch in my case)

What am I doing wrong?

did you try to import hgext.purge from a python prompt?

Hm...it gives the following:

Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import hgext.purge
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named purge

At the same time:

>>> import sys
>>> print sys.path
['', ... '/usr/local/lib/python2.6/dist-packages']

and:

>>> import hgext

...works just fine and there is
/usr/local/lib/python2.6/dist-packages/hgext/purge.py

I'm a bit lost :(

did apt-get remove the 'mercurial-common' package as well?

it's probably not the same hgext that is found

seems like apt-get doesnt remove the mercurial-common package along with mercurial
do a 'apt-get remove mercurial-common' as well

Since I have no idea what is wrong with my setup I'm just using full
paths in ~/.hgrc to built-in extensions :)

Some extensions have been turned into core commands -- the hbisect
extension is an example of this. The import errors can then occur if you
still have an old configuration file that references the no longer
existing extension. On Debian/Ubuntu, you run into this if you uninstall
Mercurial instead of purging it.

Please use

hg showconfig --debug

to see all the configuration values Mercurial pick up and especially
where they are loaded from. Then disable the extensions by editing the
corresponding files or by adding entries to your ~/.hgrc of the form:

extension = !
