snowpack inserting random index.js# into a require import. (breaking the import)

[MarkLyck]

Getting the following error trying to use memoizee with snowpack:

Could not load /Users/mark/ypm/xxxx/cloud-one2/node_modules/es5-ext/array/index.js#/e-index-of (imported by node_modules/memoizee/normalizers/get-fixed.js): ENOENT: no such file or directory, open '/Users/mark/ypm/xxxx/cloud-one2/node_modules/es5-ext/array/index.js#/e-index-of'

I checked my node modules and node_modules/es5-ext/array/#/e-index-of.js exists.

I'm not sure why the import ends up being es5-ext/array/index.js#/e-index-of (there is no index.js in the require path)

Looking at the get-fixed.js inside memoizee in the node modules. The require is perfectly fine:

var indexOf = require("es5-ext/array/#/e-index-of")

My guess is that the # freaks out snowpack somehow? Honestly I've never seen a folder called # before, and have no clue why es5-ext decided that was a good idea. But other build systems have no problems handling this.

Oh interesting. Yea, I bet this issue is that Rollup treats that as a URL, in which case "es5-ext/array/#/e-index-of" is really "es5-ext/array/" (anything after a hash in a URL isn't a part of the path itself).

Since that's a Rollup error that you're seeing I think that this is a CJS Rollup issue. If you could create a reproduction case in their issue template that would be a great first step: https://github.com/rollup/plugins/issues/new?template=BUG.md

Did you ever find a solution to this?
