How to enable chromedriver in ubuntu for python script?

  • 772

For a scheduled task I want the selenium webdriver to be executed with python script.

I have tried the following solution:

  1. https://stackoverflow.com/questions/50117377/selenium-with-chromedriver-doesnt-start-via-cron

But it has not resolved the problem.

Location of chromdriver:

~/Documents/Python/Chromedriver/chromedriver
cron 18.04 selenium

    Specify full paths in cron.

    The next cron job includes:

    • DISPLAY variable specified to access your display in case if you do not want to use headless mode. Use $ env | grep DISPLAY to get it.
    • PATH variable with path to chromedriver specifying. I've copied chromedriver to /usr/local/bin
    • Full path to python3.8
    • Full path to python script

    $ crontab -e:

    * * * * * export DISPLAY=:0; PATH=$PATH:/usr/local/bin; /usr/bin/python3.8 /home/user/PycharmProjects/seleniumtest/seltest.py build

    In your case specify path to your chromdriver location:

    * * * * * export DISPLAY=:0; PATH=$PATH:/home/user/Documents/python/Chromedriver; /usr/bin/python3.8 /home/user/PycharmProjects/seleniumtest/seltest.py build

    Note: I've created a python project in PyCharm using the next parameters:

    The script is taken from here:

    from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Chrome()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

    Additionally I have been required to install some packages:

    $ sudo apt install python3-pip
$ pip3 install selenium
$ cd ~/Downloads
$ unzip chromedriver_linux64.zip
$ sudo cp chromedriver /usr/local/bin/
