Using Selenium on Raspberry Pi with Chromium

Question

So I'm trying to run Selenium on my raspberry pi using Chromium and for some reason I can't get my python file to compile. I keep getting the following error:

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    driver = webdriver.Chrome(os.path.expanduser('/usr/bin/chromedriver.exe'))
  File "/usr/local/lib/python2.7/dist-packages/selenium-2.46.0-py2.7.egg/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
self.service.start()
  File "/usr/local/lib/python2.7/dist-packages/selenium-2.46.0-py2.7.egg/selenium/webdriver/chrome/service.py", line 75, in start
os.path.basename(self.path), docs_msg)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver.exe' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Here is the python code I'm trying to run:

from selenium import webdriver
import os

driver = webdriver.Chrome(os.path.expanduser('/usr/bin/chromedriver'))

driver.get("http://www.google.com")

driver.quit()

Any ideas?

Update

After removing the '.exe' at the end of chromedriver, it now produces the following error:

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    driver = webdriver.Chrome(os.path.expanduser('/usr/bin/chromedriver'))
  File "/usr/local/lib/python2.7/dist-packages/selenium-2.46.0-py2.7.egg/selenium/webdriver/chrome/webdriver.py", line 62, in __init__

  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__

Answer 1

Ubuntu has builds of chromium-chromedriver as .deb files for armhf.

On launchpad, therefore, you can find chromium-chromedriver armhf builds available for download. Just download the latest version, and since they have no dependencies, you can install by running dpkg -i chromium-chromedriver_58.0.3029.96-0ubuntu0.14.04.1174_armhf.deb. Then chromedriver will be available in /usr/lib/chromium-browser/chromedriver.

At the moment Chrome Driver dont support ARM processors architecture anymore.
