Thanks for the corrections and review :) I'm feeling better not being alone on this,

little detail, I don't totally agree with your last edit

"npx: installed %s in %ss": "npx: %s installé(s) en %ss",

i would keep "dans" instead of "en", but I agree for removing the "a" and adding a plural form.

@gorhgorh It was actually the first change I made (before reviewing the rest of the file).
I don't understand why you prefer "dans".
"dans" is "inside", a physical location, it's not correct for an elapsed time.

... you are totally right, I'm using a en/uk system and did not had this sentence in context. Your version is right @zkat this pr is ok to merge, and thank to @AntoineReneleau for catching this one.
