FileNotFoundError: [WinError 2] The system cannot find the file specified

Hi, while running a test example:

from arsenic.browsers import Firefox
from arsenic.services import Geckodriver
import asyncio

async def example():
    # Runs geckodriver and starts a firefox session
    async with get_session(Geckodriver(), Firefox()) as session:
          # go to example.com
          await session.get('random_url')
          # wait up to 5 seconds to get the h1 element from the page
          h1 = await session.wait_for_element(5, 'h1')
          # print the text of the h1 element
          print(await h1.get_text())
asyncio.run(example())`

I get the following error:

Any and all suggestions welcome.

arsenic was unable to find geckodriver.exe in the path. make sure it's installed and findable, or pass the binary path explicitly to Geckodriver

Thanks @ojii . I got one more if you have the time. Sorry to bother with this, I'm having a really hard time. Running the same example gives me: from pyee.asyncio import AsyncIOEventEmitter ModuleNotFoundError: No module named 'pyee.asyncio' Which is very odd because pyee.asyncio clearly exists in pyee directory in site-packages. I downloaded playwright and installed it, but it's giving me the same error.

One thing to note is that playwright and arsenic are alternatives. It would be rather unusual to use both at the same time.

[Aragonski97]

@dimaqq Understood. I think I was looking at the wrong Stack Overflow thread. Nevertheless, I tried reinstalling pyee manually, arsenic as well, but it didn't help the issue. Wondering where the problem might be.

[ojii]

pyee is not used by arsenic at all, whatever issue you're having is unrelated to this project.
