it is a hard to install all the libraries one by one. Each time you have to find out the name of the library and install it one by one. But if we know libraries like pipreqs which automatically installs all the required libraries to run the program

Step 1: Go to the directory in which your python script is present for example assume if we take this code in our directory. Let’s assume that your Python script is
import os import time import sys import fnmatch import requests import urllib.request from bs4 import BeautifulSoup from multiprocessing.dummy import Pool as ThreadPool print('test')
You can use pipreqs to automatically generate a
requirements.txt file based on the
import statements that the Python script(s) contain. To use
pipreqs, assuming that you are in the directory where
example.py is located:
Run this command on your PC to install the pipreqs library.
pip install pipreqs pipreqs
It will generate the following
requirements.txt file. The requirement file will look like this in our case.
which you can install with:
pip install -r requirements.txt
Other useful command…
Use pip list to get a full list installed python packages.
