Question: I have a python code in PyCharm in which i am using
import requests
but the terminal is showing me the following error:

(venv) ahmad@Ahmad:~/Desktop/Spiders$ python test.py
Traceback (most recent call last):
 File "test.py", line 1, in 
 import requests
ModuleNotFoundError: No module named 'requests'

But I have installed pip and requests as well.

Answer: 
you can use this : 

just go to file > sitting > project : name > project interpreter > add > search and install
I had to go to the CLi (command line) and run ">pip install requests" - this after trying unsuccessfully from the Pycharm 'Setting/Interpreter' gui menu.
