duplicity

[niklassaers]

Hi, "brew install duplicity" works fine, but when running "duplicity" from the command line, it gives the following on Mavericks:

$ duplicity
Traceback (most recent call last):
File "/usr/local/bin/duplicity", line 42, in
from duplicity import log
ImportError: No module named duplicity

Reproduced on three systems, including one freshly installed with just Xcode and homebrew

Any suggestions to what I should do to solve this?

Please provide your brew --config and brew doctor as well.

$ duplicity -V
duplicity 0.6.22

10.9 here, I dunno.

I would suggest brew rm duplicity, then brew update, then reinstall. Since these this issue was opened, Homebrew changed how it deals with Python software and there has been a new version of Duplicity.

If this still doesn't work:

$ duplicity --version
duplicity 0.6.23

open a new issue with updated troubleshooting information.

Confirmed. :-) Thanks!
