python - scons and virtualenv import issue -

-

i have been working ubuntu 12.04 long time , use scons compile code. using virtualenv (and virtualenvwrapper).

today tried ubuntu 14.04 on vm (future here come :) ).

when run scons (inside virtualenv) failed because can't find package (psutil doesn't matter one). confused because pip installed -r requirements.txt , know psutil there.

to sure tried pip freeze | grep psutil , saw there. after short research found out scons version on 14.04 newer 1 have on 12.04. (2.3.0 , 2.1.0 respectively).

i tried understand can cause such thing happen , saw older scons uses #! /usr/bin/env python while new scons uses #! /usr/bin/python. since have not installed psutil on system python scons fails.

is there better approach modify new scons use #! /usr/bin/env python?

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
