 Posted: Sat Nov 17, 2007 10:48 am Post subject: [SOLVED] Bad magic number in .../emergehelp.pyo |
 |
|
I'm beginning my more-or-less-annual world update and I'm off to a rocky start. 
After updating Portage, emerge was broken as follows: | Code: | Traceback (most recent call last):
File "/usr/bin/emerge", line 35, in ?
import emergehelp, xpak, commands, errno, re, socket, time, types
ImportError: Bad magic number in /usr/lib/portage/bin/emergehelp.pyo |
A little investigation turned up two different byte-code versions of that module: | Code: | ~ # cd /usr/lib/portage/bin
bin # ll emergehelp*
-rw-r--r-- 1 root root 21804 2004-03-11 22:50 emergehelp.pyc
-rw-r--r-- 1 root root 20853 2003-11-14 22:35 emergehelp.pyo
bin # file emergehelp.pyc
emergehelp.pyc: python 2.2 byte-compiled
bin # file emergehelp.pyo
emergehelp.pyo: python 2.2 byte-compiled |
Removing the offending file seemed to convince Python to pick up the newer one: | Code: | bin # mv emergehelp.pyo _emergehelp.pyo
bin # emerge --info

I re-merged Portage to be safe and it finished without error this time. Any chance I now have a half-and-half Portage installation, with mixed pieces from different versions? I'd like to be sure Portage is A-OK before I move on...there are scary monsters like expat lurking about and I want to face them fully-armed.

| There shouldn't be any problems with removing byte-code files. |

I knew the Shadow would know ... 
Thanks--I thought as much but wanted to be sure.

Thanks a lot!
This useful and small tip has helped me out, even if it's about three years later.
The problem appeared, when I touched an old computer that I hadn't run in about 1.5 years and the first thing I ran was "emerge -av --oneshot portage"
Once again the gentoo forums has saved my day and shortened my error searching by one to two hours 
Cheers,
geta
