Problem with Node.js v12.0.0 REPL?

[chrisveness]

Has Node.js v12.0.0 broken something to do with using esm in the REPL?

$ npm install geodesy esm

$ nvm use 11.14.0
Now using node v11.14.0 (npm v6.7.0)
$ node -r esm
> import LatLon from 'geodesy/latlon-spherical';
undefined
> d = new LatLon(52, 0).distanceTo(new LatLon(48, 2));
467138.7758206903

$ 

$ nvm use 12.0.0
Now using node v12.0.0 (npm v6.9.0)
$ node -r esm
Welcome to Node.js v12.0.0.
Type ".help" for more information.

Or is there something we should be doing differently now?

(This is with esm v3.2.22).

I'm getting this error as well, from importing at the REPL with 12.0.0 and 12.1.0.

Yep. No need for others to confirm. I've been meaning to move to a more thorough hook for the REPL.

I'm guessing it's time :)

tests are also failing in Node.js v12 because there's no binary for sleep available (darwin)
