import fcntl - error

I've just installed pymux, but can't run it. Error:

Same error here. fcntl is Posix only, so pymux is not designed to run on Windows.

Same issue here. Damn i tough this would work on Windows. :(

Hi @dCosminn,

The latest master branch should run on Windows 10, but only using pymux standalone for now.
I didn't release it yet, because it's not completely stable yet.

It depends on prompt_toolkit 2.0 and uses yawinpty. Given that yawinpty was removed from GitHub and that winpty is already a hack to begin with, I'm waiting for the next Windows release that supports true PTYs. This will make the Windows implementation super clean.
See: https://blogs.msdn.microsoft.com/commandline/2018/08/02/windows-command-line-introducing-the-windows-pseudo-console-conpty/

That sounds awesome!
But in my case I was going to run it on a VPS which has Windows Server 2012.

The same problem. I was going to run it on a win 7, so, someone knows if there is a workaround for this problem?

Update:
I try to run pymux after update prompt_toolkit from prompt-toolkit-1.0.15
to prompt-toolkit-2.0.4, but I got an error:
