Selenium using Python – Geckodriver executable needs to be in PATH

selenium.common.exceptions.WebDriverException: Message: geckodriver executable needs to be in PATH.

First of all you will need to download latest executable geckodriver from here to run latest Firefox using Selenium

Actually, the Selenium client bindings tries to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

  • On Unix systems you can do the following to append it to your system’s search path, if you’re using a Bash-compatible shell:

      export PATH=$PATH:/path/to/directory/of/executable/downloaded/in/previous/step
  • On Windows you will need to update the Path system variable to add the full directory path to the executable geckodriver manually or command line** (dont forget to restart your system after adding executable geckodriver into system PATH to take effect)**. The principle is the same as on Unix.

Now you can run your code same as youre doing as below :-

from selenium import webdriver

browser = webdriver.Firefox()

selenium.common.exceptions.WebDriverException: 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

The exception clearly states you have installed Firefox some other location while Selenium is trying to find Firefox and launch from the default location, but it couldnt find it. You need to provide explicitly Firefox installed binary location to launch Firefox as below :-

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary(path/to/installed firefox binary)
browser = webdriver.Firefox(firefox_binary=binary)

For Windows:

Download the file from GitHub, extract it, and paste it in Python file. It worked for me.

For me, my path path is:


This solved it for me.

from selenium import webdriver
driver = webdriver.Firefox(executable_path=ryourpathgeckodriver.exe)

Selenium using Python – Geckodriver executable needs to be in PATH

This steps solved it for me on Ubuntu and Firefox 50.

  1. Download geckodriver

  2. Copy geckodriver to folder /usr/local/bin

You do not need to add:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities[marionette] = True
firefox_capabilities[binary] = /usr/bin/firefox
browser = webdriver.Firefox(capabilities=firefox_capabilities)
