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.
Step-by-Step Solution
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.
