A hidden library? - BillMcEnaney - Apr-01-2019
Hi everyone,
I'm new here because I need to help a friend of mine who runs Python on a Linux platform. To install a Python library on that platform, he ran pip and he knows that the library lives on his hard disk. But the computer can't find that library. Do you think there's a typo in a path name that should point to that library? What else could cause my friend's trouble? He says that he hasn't edited his bash profile. Thanks.

He has to check if pip is really installing modules for the python interpreter that he is running his scripts.
He can investigate it with:
1 - Check pip version and its bond python interpreter.
$ pip -V2 - Then check if the module was really installed.
$ pip list3 - Modules that have
- in their names must be imported with _.Example:
$ pip install my-moduleAnd when importing:
import my_module

sys.path will show you where your python directories are located, and such your 3rd party libs you install. In my case it resides in usr/local/lib/python3.6/site-packages for python3.6 version
