Package from jspm includes relative link to non-existent file

Hi,

I am using rails-7 to install qr-code-styling with importmap. When it installs qr-code-styling it also installs https://ga.jspm.io/npm:@jspm/[email protected]/nodelibs/browser/buffer.js which contains the following:

import{d as r}from"../../_/C7GZrc4O.js";const a=r();a.Buffer;a.SlowBuffer;a.INSPECT_MAX_BYTES;a.kMaxLength;var f=a.Buffer;var e=a.INSPECT_MAX_BYTES;var t=a.kMaxLength;export{f as Buffer,e as INSPECT_MAX_BYTES,a as default,t as kMaxLength};

Obviously this causes an error as there is no such file ../../_/C7GZrc4O.js.

Is this a bug or is the 'buffer.js' somehow invalid?

The file ../../_/C7GZrc40.js very much does exist - https://ga.jspm.io/npm:@jspm/[email protected]/_/C7GZrc4O.js.

I think this might be related to the problem with the Rails implementation of downloading import maps, which doesn't support downloading packages as folders of modules, only as single files.

Would the work around be to 'pin' the entire '[email protected]'? Or is there a better solution?

I think treating packages as folders to download as opposed to files using the folder API (https://jspm.org/cdn/api#download) remains the fix for Importmap Rails, which I have suggested before. Someone just needs to work on a PR for that.
