SELENIUM_WEB_DRIVER_ERROR_MSG = b'''The error message you are receiving is due to the `geckodriver` executable not 
being found in your system\'s PATH. To resolve this issue, you need to download the geckodriver and add its location 
to your system\'s PATH.\n\nHere are the steps to resolve the issue:\n\n1. Download the geckodriver for your platform 
(Windows, macOS, or Linux) from the following link: https://github.com/mozilla/geckodriver/releases\n\n2. Extract the 
downloaded archive and locate the geckodriver executable.\n\n3. Add the geckodriver executable to your system\'s 
PATH.\n\nFor macOS and Linux:\n\n- Open a terminal window.\n- Move the geckodriver executable to a directory that is 
already in your PATH, or create a new directory and add it to your PATH:\n\n```bash\n# Example: Move geckodriver to 
/usr/local/bin\nmv /path/to/your/geckodriver /usr/local/bin\n```\n\n- If you created a new directory, add it to your 
PATH:\n\n```bash\n# Example: Add a new directory to PATH\nexport PATH=$PATH:/path/to/your/directory\n```\n\nFor 
Windows:\n\n- Right-click on "My Computer" or "This PC" and select "Properties".\n- Click on "Advanced system 
settings".\n- Click on the "Environment Variables" button.\n- In the "System variables" section, find the "Path" 
variable, select it, and click "Edit".\n- Click "New" and add the path to the directory containing the geckodriver 
executable.\n\nAfter adding the geckodriver to your PATH, restart your terminal or command prompt and try running 
your script again. The error should be resolved.'''
