Invalid Streamlink Version Despite Correct Version Being Installed

[mam8cc]

Checklist

• This is a bug report.
• Streamlink is working correctly on my system without using the Twitch GUI.
• I tried solving my issue by reading the project's wiki first.
• I used the search function to find already opened/closed issues or pull requests.

Description

After moving over from Livestreamer GUI, I've not been able to get the GUI to work with Streamlink. I have 0.2.0 of Streamlink installed and have paths set to my python install as well as the livestreamer binary.
...

Expected / Actual behavior

Expect that I can launch a stream via the GUI.

Recieve an error:

Error: Invalid Streamlink version
Your version v0.1.0 doesn't match the min. requirements (v0.2.0).

Reproduction steps

1. Launch Streamlink GUI and configure paths to python and streamlink
2. Open stream
3. See error

Environment details (operating system, etc.)

Installed the GUI from the releases: https://github.com/streamlink/streamlink-twitch-gui/releases/download/v1.1.1/streamlink-twitch-gui-v1.1.1-macOS.tar.gz
macOS Sierra 10.12.2
python 3.4.4
streamlink 0.2.0

I'm on Windows 7 SP1, 64-bit, and after updating to version 1.1.1 this problem was occurring for me as well. With version 1.0.1 this issue didn't occur. Probably related to this: streamlink/streamlink#346.
However, for me streamlink --version was returning 0.1.0, not 0.2.0 as it does for you.

I have resolved this issue by re-downloading the Streamlink 0.2.0 Windows installer, because it appears the installer was re-released. Now I can watch streams again.

@mam8cc
What's the output of running

/usr/local/bin/python3 /usr/local/bin/streamlink --version

and

cat /usr/local/bin/streamlink | head -n 1

Please also try removing the explicit python path from the settings as it shouldn't be necessary anymore since v1.1.x.

@Robby-
This was an issue related to the Windows installer of 0.2.0. I knew that this would affect some users, but I needed to publish a new release because of a critical bug of the installer of the Twitch GUI and I didn't want to revert the commit of the streamlink dependency increment. Re-downloading the Streamlink installer fixes the issue, as you've already figured out 😃

@bastimeyer If I remove the explicit path setting and attempt to launch a stream I get:

Traceback (most recent call last):
File "/usr/local/bin/streamlink", line 7, in <module>
from streamlink_cli.main import main
ImportError: No module named streamlink_cli.main

And the requested output:

# mikemcclannahan @ beetlestation in ~ [21:16:57]
$ /usr/local/bin/python3 /usr/local/bin/streamlink --version
streamlink 0.1.0

# mikemcclannahan @ beetlestation in ~ [21:17:01]
$ cat /usr/local/bin/streamlink | head -n 1
#!/usr/local/opt/python3/bin/python3.5

[bastimeyer]

You are mixing different python versions (and different streamlink versions).

The first command is the one the GUI invokes when setting the explicit python path you have posted. As you can see, it prints out 0.1.0. The third screenshot you uploaded shows that calling "streamlink" works fine. When not setting an explicit python path, the GUI uses the python executable set in the streamlink-script's shebang (/usr/local/opt/python3/bin/python3.5), which is the same as calling streamlink from the shell. I don't know your whole setup, but I'm surprised that this throws a python error when clearing the python path in the GUI.

Maybe you should clear all existing streamlink installations and start off fresh. I don't have a better answer right now 😞

I've uninstalled streamlink from every python distro I have installed. I've grepped for it across the system and cannot find it. However this is clearly a local issue. Thanks for looking.

[mam8cc]

@bastimeyer If others encounter this issue, the only thing I've had success with is installing streamlink inside a virtualenv and pointing the GUI to it.

(streamlink)
# mikemcclannahan @ beetlestation in ~/Projects/streamlink [12:55:02]
$ which python
/Users/mikemcclannahan/Envs/streamlink/bin/python
(streamlink)

$ which streamlink

# mikemcclannahan @ beetlestation in ~/Projects/streamlink [12:56:16]
$ streamlink --version
streamlink 0.2.0
(streamlink)
# mikemcclannahan @ beetlestation in ~/Projects/streamlink [12:56:28]
$ /Users/mikemcclannahan/Envs/streamlink/bin/python /usr/local/bin/streamlink --version
streamlink 0.2.0

However, now I am seeing the below issue:

Found matching plugin twitch for URL twitch.tv/summit1g

As I've shown above I can start streamlink from the command line. I can open a new issue if you'd prefer.

[bastimeyer]

Can you please add the --verbose-player custom streamlink parameter in the GUI, so you can see the VLC output? Maybe also --loglevel DEBUG

Looks like VLC doesn't support this on MacOS.

[bastimeyer]

Closing this now, since the original issue has been a client issue and the other one was fixed.

Please deselect the "Minimal player layout" option in the settings menu to be able to launch streams on MacOS with VLC.

[mam8cc]

@bastimeyer I can open a new issue if you'd like but after deselecting the "Minimal player layout" option as you recommended above, I now see the below error when launching a stream.

This looks like a VLC bug. Why is it treating a http URL as a local file name?

What happens when you run this?

streamlink -p /path/to/vlc --player-passthrough http STREAM best

Btw, switching to rtmp fixes this, as reported in the linked thread above.

[mam8cc]

Here is the output you requested. Everything works fine and the stream starts.

$ streamlink -p /Applications/VLC.app/Contents/MacOS/VLC --player-passthrough http https://www.twitch.tv/pinballjoe BEST

Switching to rtmp did in fact launch a stream. You can consider this resolved.
