Hi @ithjz Have you tried using seleniumbase install chromedriver ? It doesn't seem to be on your path.

[mdmintz]

Additionally, get the new seleniumbase version 1.15.8 to take care of those deprecation warnings you see, which are related to the version of python used. Also, add a "--upgrade" to your pip install to make sure you have the latest versions of python packages being used: pip install -r requirements.txt --upgrade

[mdmintz]

@ithjz Now, v1.15.10 should take care of the remaining DeprecationWarnings you saw (https://github.com/seleniumbase/SeleniumBase/pull/209/files), which updated methods that use regular expressions to pass raw strings. Use pip install -U seleniumbase --no-cache-dir to reinstall from pypi, (Or pip install -U -i https://pypi.anaconda.org/seleniumbase/simple seleniumbase if you're using Anaconda Cloud). Then get chromedriver into your seleniumbase drivers folder with seleniumbase install chromedriver.

[mdmintz]

I haven't heard back in 4 days, so I'll assume this issue is resolved. Please update to the latest version of seleniumbase if you haven't already.

[bschollnick]

(In case someone else runs into this.)
I was seeing the same issue under Windows Server.

seleniumbase install chromedriver

Worked fine, no errors, but seleniumbase would die with "cannot find Chrome Binary".

For some reason, I HAD to use seleniumbase install chromedriver latest.

As soon as I did that, everything worked fine.

[bukowa]

  ** install **

  Usage:
          seleniumbase install [DRIVER_NAME] [OPTIONS]
              (Drivers: chromedriver, geckodriver, edgedriver,
                        iedriver, operadriver)
  Options:
          VERSION         Specify the version.
                          (Default chromedriver version = 2.44)
                          Use "latest" for the latest version.
          -p OR --path    Also copy the driver to /usr/local/bin

It would be cool to specify custom path!

[mdmintz]

@bukowa It can always be copied to another location, but these are the safe paths to use. There could be permissions issues, etc, when using other paths. The only time that the seleniumbase/drivers folder isn't good enough is when using a Selenium Grid - that requires the driver to be on the system path. Otherwise, it's safer to use seleniumbase/drivers because then you could have a different version of the browser driver for different virtual environments. If the system path is used, all users would have to use the same driver.

I wonder why it still doesn't work out of the box with venv :/

[bukowa]

It works with firefox seleniumbase install geckodriver pytest --headed --browser=firefox

[mdmintz]

@bukowa cannot find Chrome binary means that Chrome wasn't found on your machine. Chrome must be installed separately. (SeleniumBase only downloads the drivers for you.)

Oh ok thank you
