Everytime I type repomix --version this annoying error message shows up.

A simple workaround that worked for me was setting the NODE_OPTIONS environment variable to disable the experimental warning:

Windows (Powershell)

$env:NODE_OPTIONS="--disable-warning=ExperimentalWarning"
repomix

Alternatively, on Linux or macOS:

export NODE_OPTIONS="--disable-warning=ExperimentalWarning"
repomix

@rockmandash
This suppresses the warning whenever you run repomix. I hope it helps!

Thank you @rockmandash for reporting this issue and @roooxnode for providing the workaround solution!
Sorry for the late response.

It seems this warning is occurring because the debug package (used via secretlint) is trying to load supports-color (ESM) using require().
debug-js/debug#912

I'll investigate this further.

I've investigated and found the root cause.

This seems to be an npm cli issue itself. The warning will be gone when you update to Node.js v23.4.0.
