Selenium is a popular web browser automation library used for web scraping. To run, however, Selenium needs special web browser executables called drivers. For example, to run Firefox web browser Selenium needs [geckodriver](https://github.com/mozilla/geckodriver/releases) to be installed. Without it a generic exception will be raised:

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



This can also mean that the geckodriver is installed but Selenium can't find it. To fix this the geckodriver location should be added to the `PATH` environment variable:

shell```shell
$ export PATH=$PATH:/location/where/geckodriver/is/
```



Alternatively, we can specify the driver directly in the Selenium initiation code:

python```python
from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')
driver.get('https://scrapfly.io/')
```
