Virtualenv will not reference warnings.py for python 2.7

I have a problem creating virtualenv (1.5.2) from python2.7 on Lucid. Virtualenv seems to skip creating a symlink for warnings.py.

Running virtualenv with interpreter /usr/local/bin/python2.7

The warnings.py file is located in / usr / local / lib / python 2.7 /.

No problem to create virtualenv with python2.6.

So, I checked the virtualenv.py file and it has a REQUIRED_MODULES list, which seems to have the names of the modules to attach to the / lib dir of the new environment. This list is expanded through module “warnings” after the condition is met:

sys.version_info[:2] >= (2, 6)

python , virtualenv.py . , virtualenv, virtualenv.py.

virtualenv.pyc python dist- . , , - virtualenv - pythons.
