so, i wanted to work with selenium with python but everytime i get an error.
    Traceback (most recent call last):
  File "/home/lario/.local/lib/python3.5/site-packages/selenium/webdriver/common/service.py", line 74, in start
    stdout=self.log_file, stderr=self.log_file)

    restore_signals, start_new_session)

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
  File "a.py", line 7, in <module>
    browser = webdriver.Firefox(firefox_binary=binary)

    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH. 
i have tried to run this code
export PATH=$PATH:/home/lario/Desktop/workstation/geckodriver
but it just keeps saying this. Is there a way to put this in all directories? And how do i fix the first error?
