selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Opera binary with OperaDriver Selenium and Python

问题

I just tried to get an easy Python script to work, which should only open up google.

I installed selenium with pip and placed the operadriver, downloaded from the selenium page, into my python path. Also watched many videos about it, but I can't find a solution..

Here's the code:

from selenium import webdriver
import time

driver = webdriver.Opera()
driver.get('http://www.google.com')

The error:

Traceback (most recent call last):

    driver = webdriver.Opera()

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Opera binary
  (Driver info: OperaDriver=2.40 (a50783a565882ef2022bea655e8560f37ecf8afe),platform=Windows NT 6.1.7601 SP1 x86_64)

...implies that the Opera Browser binary wasn't found at the required location.

Your main issue is the Opera Browser is not installed at the default location. So you need to mention the absolute path of the location where Opera Browser is installed as follows:

from selenium import webdriver
from selenium.webdriver.opera.options import Options

options = Options()
options.binary_location = r'C:\path\to\opera.exe'
driver = webdriver.Opera(opera_options = options, executable_path=r'C:\Utility\BrowserDrivers\operadriver.exe')
driver.get('http://www.google.com')
