I think I prefer the current wording because it gives more of a hint on why the error is occurring. That the versions are incompatible kind of follows from the rest of the message, right?

I guess I'm trying to avoid "uses the internals of Node.js in an invalid way" as it seems likely to be seen as throwing a bit of shade at npm. But I may be overthinking it.

Beyond that, my thinking was that the user needs to know the versions are incompatible, and why (or whose responsible for the situation) are secondary.

All that said, I'm fine with the current wording.

@Trott yup, updated!

"either the version of npm that is bundled with Node.js, or "
"a version of npm (> 5.5.1 or < 5.4.0) or node-tar (> 4.0.1) "
"that is compatible with Node 9 and above.\n");
