Settings

CHROMEDRIVER_PATH

Override this variable to address the binary file of chromedriver of your own.

SELENIUM_DELAY

To set delay on selenium requests (default 3). it will last that amount of time crawling requested page before closing the session and create pdf of it.

Installation Chrome

Be noted to use this package google-chrome in your os. To install on ubuntu use following commads:

sudo curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add 
sudo bash -c "echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' >> /etc/apt/sources.list.d/google-chrome.list" 
sudo apt -y update 
sudo apt -y install google-chrome-stable 

Exceptions

1- Message: session not created: This version of ChromeDriver only supports Chrome version 90 Current browser version is 103.0.5060.53 with binary path /usr/bin/google-chrome

If you faced a problem like this, you should address the correct chromedriver binary in your codes. To do that download the proper chromedriver version and place in your OS. Then address it with following option in your settings.py file:

CHROMEDRIVER_PATH = '/usr/bin/chromedriver'

Also you can use below script to automatically fix this problem:

pip install webdriver-manager

Then use the driver in python as follows

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())
