Smashing won't load: bundler: failed to load command: thin (/usr/local/bin/thin)

[jason-mehmel]

Describe the bug A clear and concise description of what the bug is.

When I type smashing start I get an error response as well as a traceback of the commands.

I will produce the traceback here!

same problem

[kinow]

Sorry, haven't had time to work on this yet.

[JCluzet]

I just find... one smashing was already start (port is in use) was precise at the end

[kinow]

no acceptor (port is in use or requires root privileges) (RuntimeError)

Would it be possible, when this error occurs, to run a command to list the ports used, please? For example, for Ubuntu Linux this could work: netstat -tlnp. And confirm there's nothing already listening on port 3030.

[oyohimura]

Seems like you can start the server on another port & host: smashing start -a 127.0.0.1 -p 8000 for instance.

Closing due to inactivity, but if others find a way to reproduce it and can confirm via netstat or starting a separate process as @oyohimura suggested, please let us know and provide a minimum reproducible test case :+1:
