Building on windows results in faulty package

[laggingreflex]

I'm on Windows and I tried to fork it and build it myself but building results in a package that always results in this error:

path.js:28
    throw new TypeError('Path must be a string. Received ' + inspect(path));
    ^

Hi @laggingreflex!

I can't repro.
I'm running Windows 10, Node 8.x, with npm 4 and able to build from the repo.

[laggingreflex]

I'm on node 8.4 npm 5

I compared the esm.js.gz built by me with the npm-installed version and there's a size difference: 42.6kB (mine) vs 43kB (installed) so there's definitely something weird going on at my end.

Could you could you upload your ./build/esm.js (uncompressed)? I could compare that to mine to get a better idea what's missing in my build.

Edit: Here's my version https://gist.github.com/laggingreflex/32140cf1bcdedfef6f23eaa3912f1a3e

The build size difference is expected since our master branch is where WIP bits are.
Are you able to npm i, npm test, and npm run test:prod successfully?

Tests are working, but can't use it outside the library for some reason.

Setting the package version to 0.7.1 (from 0.7.0) and then building again solves the issue! Not sure why.

I got this hint (of upgrading version) while debugging the webpack build. Somewhere the values being passed looked like this:

  map:
   { raw: [Function],
     versions: [ '0.7.0' ],
     wrappers: { '0.7.0': [Function: methodWrapper] } },
  range: '>=0.7.1 <0.8.0' }

Edit: Don't know why I had version 0.7.0 to begin with. Maybe I had switched to a previous tag while testing.
