Selenium Geckodriver and ChromeDriver not working

Question

Running OS 10.12.6 Selenium with Python 3.6 bindings

Despite my best efforts I can't seem to get either working with Selenium. Here's the error I get:

Geckodriver error:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The error for both chromedriver and geckodriver are essentially the same.

I've manually set my path to where these are located. Same error. I've moved the drivers to a location already in the path. Same error. Ive removed the two versions I downloaded and installed both drivers via Homebrew. Same errors. I'm not sure what to do next.

Answer 1

Homebrew needed to link the drivers. Once this was done they worked perfectly.

Answer 2

I am able to use chromedriver now without a problem. I set chromedriver.exe in a file folder renamed chromedriver, then I make sure the filepath is in parentheses. I however have the same problem with opening geckodriver through selenium despite the fact that pathlib.Path recognizes that the geckodriver.exe file exists. See if you can get chromedriver working this way:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

browser=webdriver.Chrome(r'c:\path_to_chromedriver\chromedriver\chromedriver.exe')

As in the last line above, you should make certain that you include the file path in the form of a raw string (the raw string making sure that Python doesn't read the backslashes as escape characters). If you do ever figure out how to solve your problem with geckodriver (as I have tried adding it to the system Path through advanced settings yet it didn't work), please let me know, but that should get Selenium working with Chrome.

Answer 3

Hi I have created new bash script which installs automatically geckodriver, firefox, python, selenium and tests the configuration.

#!/bin/bash

apt update && apt install -y firefox python3 python3-pip
pip install selenium
INSTALL_DIR="/usr/local/bin"
json=$(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest)
input=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("linux64"))')
urls=$(echo $input | tr " " "\n")
for addr in $urls
do
        url=$addr
        break
done
curl -s -L "$url" | tar -xz
chmod +x geckodriver
sudo mv geckodriver "$INSTALL_DIR"
echo "installed geckodriver binary in $INSTALL_DIR"
python3 -c "from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)
driver.get(\"http://google.com/\")
print (\"Headless Firefox Initialized\")
driver.quit()"
