Getting the error after trying to play any stream. Tested on streamlink cli and the streams open up in mpv as intended. This is after uninstalling livestreamer and livestreamer-twitch-gui. Using the same settings as before. Changing player executable to mpv and using hls as stream type.

Hi there, I was getting the exact same error and my setup/situation is identical (migrating from livestreamer to streamlink), and this fixed it for me:

Go to Settings -> Streamlink -> Python Executable

I changed pythonw.exe to C:\Program Files (x86)\Streamlink\Python\pythonw.exe (or find pythonw.exe wherever you installed streamlink).

The “Unexpected version check output” error message means that the validation of Streamlink failed (see the tracelog). Please make sure that Streamlink and its own dependencies do work with the python version you’re using, especially if you’ve already installed python on your system.

This is what Streamlink Twitch GUI does while validating Streamlink: If no custom path was defined, then it will first look for the python executable (pythonw.exe on Windows) in one of the directories defined in the system’s PATH environment variable. If it can’t find it, then it will look for it in a list of known fallback paths, which includes the default path of the Streamlink installer. The same is also being done for the streamlink-script.py file. This ensures that an installation via pip does also work, since the folder is usually included in the PATH var.

See the default config: https://github.com/streamlink/streamlink-twitch-gui/blob/v1.0.0/src/config/streamprovider.json#L17-L60

I knew that the transition might be a bit unsmooth, because Streamlink doesn’t use the same bundler as Livestreamer did with its installer. This is why I included the “please re-validate your Streamlink/Livestreamer configuration” in the changelog. I think I need to add all this to the installation guide in the wiki.

Thanks for already helping here, @danepark

Btw, I’ll leave this thread open, because I have the feeling that there will be more people with the same problem and I don’t want multiple threads.
