Wing version 7.2 unable to load executable Python with activated env

edit

I'm trying to load executable python with a django virtual env. I'd used what I usually do to load my virtual env as indicated monvenv/bin/activate and I get the following message what am I doing wrong. Thank you for your help RUNNING IN INTERP: CMD=u'monvenv/bin/activate'; ARGS=[u'monvenv/bin/activate', u'/home/christian/.wingpro7/updates/7.2.2.9/bin/ide-2.7/src/wingbase/execonearg.py', "import sys, os, keyword; sys.stdout.write('VERSION=%d.%d.%d\n' % ((sys.hexversion & (0xff << 24)) >> 24, (sys.hexversion & 0x00ff0000) >> 16, (sys.hexversion & 0x0000ff00) >> 8)); sys.stdout.write('PYTHONPATH=' + os.pathsep.join(sys.path) + '\n'); sys.stdout.write('EXECUTABLE=' + sys.executable + '\n'); sys.stdout.write('PREFIX=' + sys.prefix + '\n'); sys.stdout.write('BASEPREFIX=' + getattr(sys, 'base_prefix', 'None') + '\n'); sys.stdout.write('KEYWORDS=' + ' '.join(keyword.kwlist) + '\n'); sys.stdout.write('BUILTINS=' + ' '.join(dir(__builtins__)) + '\n'); sys.stdout.write('END OF OUTPUT FOR WING INSPECTION' + '\n')"]
