Currently I'm able to install webbot but not instantiate Browser

>>> web = Browser()

AFAICT, there is no ChromeDriver binary available for aarch64. The only version for Linux that the Chromium project ships is compiled for x86-64.

If you're using a raspberry pi (Which I guess is just arm64, but you might try something similar), this appears to be a workaround: (Tested on a raspberry pi 4, python 3.7.3)

open terminal: pip3 install webbot

sudo apt install chromium-chromedriver

sudo cp /usr/lib/chromium-browser/chromedriver /usr/local/lib/python3.7/dist-packages/webbot/drivers/chrome_linux

You'll have to run as su, unless you comment out os.chmod(driverpath , 0o755 ) I'm sure this driver could be added to the project.

tgikal - I have tried your solution on raspberry pi but I am getting: selenium.common.exceptions.WebDriverException: Message: chrome not reachable (Session info: chrome=86.0.4240.197) Do you have any idea what can be wrong?

tgikal commented 3 years ago

Mykadlo - The driver is not finding a version of chromium it likes.

I haven't needed to update this for a while, so I don't have anything to test it on. I can only suggest making sure everything is up to date, sudo apt update sudo apt upgrade make sure chromium is installed: sudo apt install chromium Make sure the location /usr/lib/chromium-browser actually contains the chrome driver, they may have moved it or something. cd /usr/lib/chromium-browser, dir check what version python you're using: python3 --version and copy the driver to the relevant webbot driver folder.

It's currently working for me with python 3.7.3-1, chromium 78.0.3904.108-rptl, chromium-chromedriver 78.0.3904.108-rptl, and webbot 0.1.4 (selenium 3.141.0)

Edit - So yeah, I'm running a way older version of webbot, I'd look at what they've changed in the driver usage since then. I'd try downgrading selenium to 3.141.0: sudo pip3 uninstall selenium sudo pip3 install selenium==3.141.0 Its only 2 versions old and they're not super focused on making things work for the raspberry pi.

thanks tgikal. I am just adding what worked for me:

sudo apt install chromium
sudo apt-get install chromium-chromedriver

this installed /usr/lib/chromium-browser/chromedriver which is symlink to chromedriver.

Then I replaced chrome-linux file in webbot/drivers directory with symlink to chromedriver, in my case like this: sudo mv chrome_linux chrome_linux_bak sudo ln -s /usr/lib/chromium-browser/chromedriver chrome_linux
