Hi, everyone
I’m a newbie in using home assistant. Please bear with me.
If you have any ideal, please let me know. I will try it.
I try to run python code in VS code server in home assistant. But it is not work. I’ve searched a lot but couldn’t find a solution. I have spent a lot of time on this topic. So I decided to ask here. Maybe someone can give me direction. Or if I still lost somethings to check, please kindly let me know. Thanks.
First, I provde my environment information.
Raspberry pi3
Home Assistant 2023.2.5
Supervisor 2023.01.1Operating System 9.5Frontend 20230202.0 - latest
Python code as below:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-gpu')
driver = webdriver.Chrome('/usr/bin/chromedriver', options=chrome_options)
driver.get('https://www.google.com/')
inputElement = browser.find_element_by_name("q")
inputElement.send_keys("Selenium")
inputElement.submit()
resultLocator = "#rso > div:nth-child(1) > div > div > div.Z26q7c.UK95Uc.jGGQ5e > div > a > h3"
browser.implicity(10)
results = browser.find_elements_by_selector(resultLocator)
print(results.text)
driver.close()
It will use selenium and chromedriver to control web browser to got information I need.
But It didn’t work when I ran it. The error message as below:
Traceback (most recent call last):

I give the path of the chromedriver directly.
driver = webdriver.Chrome('/usr/bin/chromedriver', options=chrome_options)
It’s still not work. The error message is the same.
I try to give the path of the chromium-browser
chrome_options.binary_location = '/usr/bin'
driver = webdriver.Chrome('/usr/bin/chromedriver', options=chrome_options)
error messge as below:

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/ is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
Base on error message, I confrimed few things by myself
-
I checked the chromedriver version and chromium browser version. The result that is the same.
-
I make sure the system environment include /usr/bin. It’s ok.
-
I confirmed selenium has been installed in the VS Code Server. It’s OK.
Everything seems to be find. I really don’t know what’s going on.
