Issue with starting Lucky server

Question

I've just installed crystal and the lucky framework. I am on windows 10 using WSL2. This is the error message

Unhandled exception: Unable to get file info: '/mnt/c/Python27/overmind': Input/output error (File::Error)

Answer 1

For Lucky, Overmind is actually not recommended when using WSL2 https://luckyframework.org/guides/getting-started/installing#process-manager

Also see this issue on Overmind for more information https://github.com/DarthSim/overmind/issues/88

I haven't used WSL with Lucky, but I would imagine Forego or Foreman may work better.

For just a little more background on this, Lucky uses a Process manager to boot both the Crystal webserver, as well as the webpack dev server since Lucky comes with webpack (through Laravel Mix) by default.

Answer 2

lucky-cli has swapped to use nox as the process runner so this should no longer by an issue:
