If you are a developer working on browser automation tasks, you might have come across an error message that says "Message: geckodriver executable needs to be in PATH." This error usually occurs when running a Selenium script using the Firefox browser.
Fortunately, this error is easy to fix. In this guide, we will provide a step-by-step solution to resolve this error and get your automation tasks back on track.
Download the latest version of geckodriver from the official Mozilla repository at https://github.com/mozilla/geckodriver/releases.
Extract the geckodriver executable file from the downloaded ZIP file.
Move the extracted geckodriver executable file to a directory that is included in your system's PATH. For example, you can move the file to the /usr/local/bin directory on macOS or Linux systems.
Set the executable permission for the geckodriver file using the command:
chmod +x /path/to/geckodriver
Run your Selenium script again. The error message should no longer appear, and your automation task should run smoothly.

Geckodriver is a proxy for using WebDriver to interact with the Gecko-based browsers, such as Firefox.
Q2. Why do I need to move the geckodriver executable file to a directory that is included in my system's PATH?
Moving the geckodriver executable file to a directory that is included in your system's PATH allows the operating system to find the file and execute it when needed.
Q3. How do I check if geckodriver is installed on my system?
You can check if geckodriver is installed on your system using the following command:
If geckodriver is installed, the command will return the path to the executable file. Otherwise, the command will not return anything.
Q4. Can I use geckodriver with other Gecko-based browsers, such as Thunderbird?
Yes, geckodriver can be used with other Gecko-based browsers, such as Thunderbird.
Q5. What should I do if the error message still appears after following the step-by-step solution?
If the error message still appears after following the step-by-step solution, try restarting your computer and running your Selenium script again. If the error persists, check if there are any conflicting geckodriver installations on your system and remove them.
