I have a lot of problems that I don't understand with python and its different versions. I am doing a CS50 Web online course, and I need pip3 for python 3.6 or higher. The case is that I can't use pip for python 3.6.
Under /usr/local/bin I can find different pip files: pip, pip2, pip2.7, pip3 and pip3.4. Anyway, if I run "pip" I get the message bash:
/usr/local/bin/pip: /usr/bin/python: defect interpreter. File could been not found.
How can I use the pip command in the python3.6 version?
For the course project, I should use "pip3 install -r requirements.txt" where requirements.txt has following items:
Flask
Flask-Session
psycopg2
SQLAlchemy
I tried with "python3.6 -m pip install -r requirements.txt" and I got following message:

I appreciate any help. Thanks a lot guys!
