I used pip to install a module but my program responds, "No module named..." (PYTHON) -

yes, there other questions this. however, custom modules. used pip install module , apparent reason, on command-line only, responds error. on idle , sublime/pycharm, works fine. however, running command-prompt, said, gives error. doing wrong?

if there multiple python instances, try:

python 2:

pip2 install httplib2 --upgrade 

python 3:

pip3 install httplib2 --upgrade 

to check what's installed , where, try:

pip list pip2 list pip3 list
