[🐛 Bug]: Selenium manager not found via Anaconda distribution

[Fradhyle]

What happened?

I tried to test new Selenium manager feature with Python 3.9.13 and Edge 107.0.1418.35 (Stable) (64bit), but the exception occurs.

The code I tried

from selenium import webdriver
driver = webdriver.Edge()

and the message is this
WebDriverException: Message: 'msedgedriver' executable needs to be in PATH. Please download from https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/

If I enter msedge on the 'Run' window, Edge browser opens normally.

How can we reproduce the issue?

from selenium import webdriver
driver = webdriver.Edge()

Relevant log output

Thank you!

Hmm, it's failing on conditional if not path.is_file(). Which is coming from:

Path(__file__).parent.joinpath(directory, file)

On my mac this is: /Users/titusfortner/code/seleniumhq.github.io/examples/python/venv/lib/python3.9/site-packages/selenium/webdriver/common/macos/selenium-manager

1. We should add the path to the error message so it can be investigated.
2. @symonk maybe the way I'm setting the directory doesn't work for all the weird ways people use Python?

[symonk]

@Sweetbarrow can you drop the output of this in your script:

import sys
print(sys.executable)

As a side note; we should list the files in the path etc to debug better in future. Once you have the interpreter path above can you check the file system on disk inside its lib/python.x/site-packages/* to find the directories inside selenium/webdriver/common/* for the platform

[Fradhyle]

Hi, @symonk
This is the output you requested.

C:\ProgramData\Anaconda3\python.exe

Plus, I can see selenium_manager.py inside C:\ProgramData\Anaconda3\Lib\site-packages\selenium\webdriver\common
By the way, I tried same code on Windows 11 22H2, Edge 107.0.1418.35 (Stable) (64 bit), Python 3.9.13 and the same error has raised.

[symonk]

I will get access to a windows machine and use anaconda to test it out thanks! I suspect its to do with that explicitly; as a work around you could manually put the edge driver on your path for now. Thanks for the report.

@Sweetbarrow is there a /common/windows/selenium-manager.exe file in there?

[Fradhyle]

@symonk No.
I thought it's included in the code like webdriver_manager by Sergey Pirogov, isn't it?

[Fradhyle]

@symonk I just downloaded seperate executable from Github and it works well now.
As I just said, I thought it works like webdriver_manager and didn't think it requires seperate executable.

[titusfortner]

there is a separate selenium manager executable that is distributed and it is what is figuring out which driver to get.

[Fradhyle]

@titusfortner Thank you for your answer.
It was my mistake.
