I've just started building my first bot and I'm struggling with the first step: automating a browser.

Here's my code:

from selenium import webdriver

browser = webdriver.Firefox(executable_path="/Users/ker/Downloads/geckodriver")
browser.get("https://app.finxter.com/")

When I try running the code I get the following error:

selenium.common.exceptions.SessionNotCreatedException: Message: Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line

I've installed the geckodriver unix executable and specified the path, but for some reason it still won't work and I can't really understand the error message.

You may get this error message for two reasons:

1. Firefox isn't installed in your system.
2. Firefox isn't installed in the default location within your system.

Solution:

1. If Firefox isn't installed, install it on your system.

2. If firefox isn't installed at the default location, you need to pass the path of the firefox executable through an Option() instance:

from selenium import webdriver from selenium.webdriver.firefox.options import Options

options = Options()
options.binary_location = r"C:/location/firefox.exe"
driver = webdriver.Firefox(options=options, executable_path="/Users/ker/Downloads/geckodriver.exe")
driver.get('https://app.finxter.com/')

Please check if your driver is executable you can change the permission with the command below.

chmod x /Users/ker/Downloads/geckodriver
