Re: [Duplicity-talk] duply fails to determine duplicity version

[Kenneth Loafman]

Jumping into the middle...

Scott, if you could do the equivalent of the below for us:

$ python26 pip freeze

$ python27 pip freeze

Where python26 is a symbolic link to your python 2.6 binary and python27 is to 2.7.

I'm willing to bet that fasteners is in one list but not the other.  It, and others, need to be in the 2.7 list.

firstly.. thanks for taking the time. the result looks good to me.. the last error is expected.

secondly,

looks fishy to me. what you actually should do is just install once, but with the correct path.

what i usually prefer is to install really everything in one folder and to patch duplicity to find it's modules there. i wrote a mini howto for that (see TIPS/INSTALL MULTIPLE..)
  http://duply.net/wiki/index.php/Duply-documentation

if you just simply want to install one version then

  python setup.py install --prefix=/usr/local

should be the way to go. the python binary already knows what it's PYTHONPATH is, so it automagically installs the modules in there. duplicity will end up under /usr/local/bin/ and manpage etc will end up in their proper /usr/local places. of course this can get a little messy when installing a new duplicity over that as there i no cleanup/uninstall. so you might need to do that manually in case of errors.

thx agn.. ede/duply.net
