urllib3 not found on debian but i did install python-urllib3!

[samos1808]

running command : python3 setup.py install
get following infomations:
Installing dptrp1 script to /usr/local/bin Installed /usr/local/lib/python3.4/dist-packages/dpt_rp1_py-0.1.0-py3.4.egg Processing dependencies for dpt-rp1-py==0.1.0 Searching for urllib3>=1.22 Reading https://pypi.python.org/simple/urllib3/ Download error on https://pypi.python.org/simple/urllib3/: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600) -- Some packages may not be found! Couldn't find index page for 'urllib3' (maybe misspelled?)

i check my system did installed all urllib3 but the package name on debian is python3-urllib3 and python-urllib3 .

so after installed dptrp1. running command dptrp1 i get:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pkg_resources.py", line 449, in _build_master

raise VersionConflict(dist, req)
pkg_resources.VersionConflict: (urllib3 1.9.1 (/usr/lib/python3/dist-packages), Requirement.parse('urllib3>=1.22'))

During handling of the above exception, another exception occurred:

raise DistributionNotFound(req)

any ideas about this error?

Maybe there is a separate python3-urllib3 package? Otherwise, just install urllib using pip3.
