    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

So I added geckodrive file in Path('/home/downtownhub/odermysite/env/bin'). but it happen same error. what can I solve it??

Hi there, did you upgrade Firefox somehow? selenium shouldn't ask for geckodriver if you're using the standard PythonAnywhere version of firefox... — hwjp

Ah, I see you're using a virtualenv. PythonAnywhere uses an old version of Firefox (v17) which is not compatible with the latest selenium/geckodriver. Switch back to selenium 2:

./env/bin/pip install "selenium<3"
