Let's search for PIP installation command
- pip install selenium
After install via PIP our selenium module, search for the webDriver, in this case I prefered implement Chrome webDriver, so next step to iwebDriver installation
- sudo apt-get install chromium-chromedriver (for apt repositories)
- The let's start to code...
- Open our editor end call to selenium module
- Declare variable with webDriver module and run
#!/usr/bin/python3
from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
url = 'http://www.yoururl.com'
driver = webdriver.Chrome('/usr/bin/chromedriver') <---- Call to webDriver installation router on the SO
driver.get(url)
print(driver.title)
- Then run and I fount some issues like:
Traceback (most recent call last):
File "bikes/main.py", line 12, in <module>
user = webdriver.Chrome('/usr/bin/chromedriver')
File "/home/system/craweler/local/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 81, in __init__
desired_capabilities=desired_capabilities)
File "/home/system/craweler/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
self.start_session(capabilities, browser_profile)
File "/home/system/craweler/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
response = self.execute(Command.NEW_SESSION, parameters)
File "/home/system/craweler/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
self.error_handler.check_response(response)
File "/home/system/craweler/local/lib/python2.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
- Solved addind additional parameters to webDriver declaration:
chrome_options = webdriver.ChromeOptions()chrome_options.add_argument('--headless')chrome_options.add_argument('--no-sandbox')chrome_options.add_argument('--disable-dev-shm-usage')
- Then now our webDriver declaration looks
driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)
And we've ready our selenium installation to start to be use
