Hey there, I just installed this to give it a try, but unfortunately I was greeted with the below error the first time I tried to run it.

Error details

Firstly thanks for a very well prepared bug report.

I've found the issue - it's trying to check the tmux version but tmux isn't installed. I have added some handling and it should now work correctly. Please get back in touch if it doesn't.

I've uploaded a new nuget but this often takes 30m-1h to become available. Ensure you are using 1.0.0.6.

It's also worth saying that without tmux you wont get the more fancy popup windows in your terminal but everything else should work.

Please close this issue if the issue is resolved.

I appreciate the reply. v1.0.0.6 was available, so I updated. I also went ahead and installed tmux, but it was an older version, so I pulled it down and built it, then reran dotnet-shell and it looks like everything is squared away. :+1:

Thanks, -MH
