ChromeDriver.install() bug

[Rsalganik1123]

When trying to replicate the ChromeDriver example in the documentation, I get the following error : AttributeError: 'NoneType' object has no attribute 'split'

To reproduce:

from selenium import webdriver
from selenium.common import NoSuchElementException
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())

Used to work but suddenly doesn't -- maybe there was some update I'm not aware of?

Something similar here with a slightly different error. On my Mac M3 I get the following error.

WebDriverException: Message: Service /Users/briandekeijzer/.wdm/drivers/chromedriver/mac64/119.0.6045.105/chromedriver-mac-arm64/chromedriver unexpectedly exited. Status code was: -9

I fixed this a couple of days ago by reinstalling selenium and webdriver_manager through pip. But for some reason the error is back. My env has not changed. Running the same fix doesn't resolve the issue.

To reproduce use:

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))

On Python 3.9 with selenium version 4.16.0 and webdriver-manager version 4.0.1.

Edit:

A temporary fix is to remove the .wdm folder and --upgrade the package.

rm -rf /Users/briandekeijzer/.wdm pip install --upgrade webdriver_manager

Likely culprit:

• https://github.com/SergeyPirogov/webdriver_manager/blob/master/webdriver_manager/chrome.py#L40C28-L40C51

It looks like webdriver manager can't resolve the webdriver path.

This likely means one of 3 things, it can't find chrome, it can't find chromedriver, or it can't map the correct version of chrome to the correct version of chromedriver.

I don't see how this code was ever able to work. Is it required for chrome to be installed?

in https://github.com/SergeyPirogov/webdriver_manager/blob/master/webdriver_manager/drivers/chrome.py#L54

        determined_browser_version = self.get_browser_version_from_os()
        log(f"Get LATEST {self._name} version for {self._browser_type}")
        if determined_browser_version is not None and version.parse(determined_browser_version) >= version.parse("115"):
            ...
            return determined_browser_version

        # at this point, determined_browser_version can be None if chrome is not installed, so splitting cannot work
        determined_browser_version = ".".join(determined_browser_version.split(".")[:3])
        latest_release_url = (
            self._latest_release_url
            if (determined_browser_version is None)
            else f"{self._latest_release_url}_{determined_browser_version}"
        )

I am creating a PR right away

Temporary solution is to install the webdriver manually for ubuntu: sudo apt install chromium-driver

This doesn't work for me. I alternatively installed a full-sized chrome with sudo apt install chromium.

Yeah that's the bug. I think when this repository was originally designed, it was designed with local instances of browsers in mind, and not remote browsers/browser-servers. So, with the original design, you had to have a local installation available.

I am having this same issue except I am attempting to run some scraping with Selenium in MWAA. Does anyone have any tips on how I could resolve it there?

[kmahorker]

I was running into this issue when using webdriver_manager in Python 3.

Solution:

1. Get chromedriver with sudo apt install chromium-driver
2. Skip the install and specify the Service path directly:

chromedriver_path = '/usr/bin/chromedriver' # or wherever chromedriver is installed for you
driver = webdriver.Chrome(options=options, service=Service(chromedriver_path))

For context this was the problematic code before running into the same issues others cited above:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager

options = Options()
options.headless = args.headless
driver = webdriver.Chrome(
    options=options, service=Service(ChromeDriverManager().install())
)

[LagSlug]

The simplest fix for this is just to set the driver_version, I set mine to "120" and the download worked fine. It looks like the OperationSystemManager class is unable to identify the most recent version of chrome.

def get_latest_release_version(self):
        determined_browser_version = self.get_browser_version_from_os()
        log(f"Get LATEST {self._name} version for {self._browser_type}")
        if determined_browser_version is not None and version.parse(determined_browser_version) >= version.parse("115"):
            url = "https://googlechromelabs.github.io/chrome-for-testing/latest-patch-versions-per-build.json"
            response = self._http_client.get(url)
            response_dict = json.loads(response.text)
            determined_browser_version = response_dict.get("builds").get(determined_browser_version).get("version")
            return determined_browser_version
        # Remove the build version (the last segment) from determined_browser_version for version < 113
        determined_browser_version = ".".join(determined_browser_version.split(".")[:3])
        latest_release_url = (
            self._latest_release_url
            if (determined_browser_version is None)
            else f"{self._latest_release_url}_{determined_browser_version}"
        )
        resp = self._http_client.get(url=latest_release_url)
        return resp.text.rstrip()

I think it would be a good idea to check that determined_browser_version isn't None before being split, and just set it to a hard coded default value if it is. Or it might even better better to fix upstream in get_browser_version_from_os, and make that return a hard coded default value.

Solution:

    from webdriver_manager.chrome import ChromeDriverManager
    print(ChromeDriverManager(driver_version='120').install())

Same issue here. Environment: Windows 11 Python 3.9.17 Webdriver_manager 4.0.1

error msgs:

AttributeError: 'NoneType' object has no attribute 'split'

solution: I changed shell=True to shell=False in webdriver_manager\core\utils.py, L43.

I recommend checking the system type to determine the value of this Boolean.

[zerxdapro]

Yeah, ive been having issues as well. Just confused, first time wanting to use google chrome through my bot. Just getting errors where its not finding google chrome. Am I supposed to install google chrome in my bots file? As this is in a server, not my own os.

[anonhostpi]

I think that is currently the expectation. Webdriver itself doesn't require a local installation of Chrome, but running Chrome remotely used to be a niche use case. This library was written when running remote instances wasn't very common. At least not as common as running it locally.

Technically, you only need chrome installed. I don't believe that this library actually launches Chrome.

[debthomaz]

I'm also getting this error and I don't know why, because I have Chrome installed.

[debthomaz]

Hello guys! Worked for me to download the chromedriver with the same version as my browser, using the link from this website: https://googlechromelabs.github.io/chrome-for-testing/#stable

And then I just provided the path like this:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

service = Service(executable_path='CHROME_DRIVER_PATH')
browser = webdriver.Chrome(service=service)

[KuleRucket]

This Solution written above works great for me running python under cygwin/Mobaterm. I think maybe the library is getting mixed up about whether I'm using Windows or Linux.

    from webdriver_manager.chrome import ChromeDriverManager
    print(ChromeDriverManager(driver_version='120').install())
