I am attempting to configure the headless version of Chrome on my Mac, but I encounter errors during the process. I followed various instructional guides for assistance, but I’m still running into troubles. Previously, I had success with a headless browser setup using PhantomJS, yet I understand it’s no longer recommended by Selenium. This is my current code implementation:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--headless')
webdriver_instance = webdriver.Chrome(options=options)
webdriver_instance.get('http://www.example.com')
print('Headless Chrome is set up and running')
However, I receive the following error:
Traceback (most recent call last):
File "headless_browser.py", line 47, in <module>
webdriver_instance = webdriver.Chrome(options=options)
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
Any guidance on how to resolve this issue would be greatly appreciated.
Make sure Chrome is installed on your Mac and the path to the chromedriver executable is correctly configured. You can specify the chromedriver path directly in your code like so:
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
service = Service('/path/to/chromedriver')
options = webdriver.ChromeOptions()
options.add_argument('--headless')
webdriver_instance = webdriver.Chrome(service=service, options=options)
webdriver_instance.get('http://www.example.com')
print('Headless Chrome is set up and running')
Replace /path/to/chromedriver with the actual path where chromedriver is installed. You can also try setting the CHROME_BINARY environment variable to the path of your Chrome binary.
The error you're encountering is typically due to the Chrome binary not being correctly located by Selenium. Here's a structured approach to ensure your Chrome browser runs in headless mode:
First, verify that both Chrome and the corresponding version of chromedriver are installed on your Mac. You can check your Chrome version by going to chrome://settings/help in your browser. Once you know the version, visit the ChromeDriver download page to download the appropriate driver.
Place the chromedriver somewhere convenient and take note of its path. You can include the path to your chromedriver in your script as shown below:
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
# Set the path to the chromedriver
chromedriver_path = '/path/to/chromedriver'
# Define the service and options
service = Service(chromedriver_path)
options = Options()
options.add_argument('--headless')
options.add_argument('--no-sandbox') # useful for some environments
options.add_argument('--disable-dev-shm-usage') # useful to overcome memory issues
# Initialize the webdriver with specified options and service
webdriver_instance = webdriver.Chrome(service=service, options=options)
webdriver_instance.get('http://www.example.com')
print('Headless Chrome is set up and running')
Make sure to replace '/path/to/chromedriver' with the actual path to your downloaded chromedriver.
If issues persist, you may need to specify the environment variable CHROME_BINARY directly in your script, ensuring Selenium points to the correct Chrome executable:
import os
os.environ['CHROME_BINARY'] = '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome'
Include this snippet before initializing the webdriver if needed. Replace the path if your Chrome is installed in a different location.
Following these steps should help resolve the WebDriverException you're facing. If problems continue, double-check the file permissions of the chromedriver and make sure it's executable by running chmod +x /path/to/chromedriver in your terminal.
