Generated commonJS files with undefined values

[luca-tardito]

🐛 bug report

When building using Parcel a package exporting a dependency from another package the resulting commonJS file contains undefined values.

🎛 Configuration (.babelrc, package.json, cli command)

json workspace-a

{
    "name": "workspace-a",
    "version": "1.0.0",
    "source": "src/index.js",
    "main": "dist/main.js",
    "module": "dist/module.js",
    "dependencies": {
        "cross-env": "5.0.5"
    }
}

json workspace-b

{
    "name": "workspace-b",
    "version": "1.0.0",
    "source": "src/index.js",
    "main": "dist/main.js",
    "module": "dist/module.js",
    "dependencies": {
        "cross-env": "5.0.5",
        "workspace-a": "1.0.0"
    }
}

🤔 Expected Behavior

The output commonJS file for workspace-b should be:

var $3bJ5v$workspacea = require("workspace-a");

function $parcel$export(e, n, v, s) {
  Object.defineProperty(e, n, {get: v, set: s, enumerable: true, configurable: true});
}

$parcel$export(module.exports, "functionB", () => $5d4f15474cde7d38$export$5ab94df7ac192afc);
$parcel$export(module.exports, "functionA", () => $3bJ5v$workspacea.functionA);

const $5d4f15474cde7d38$export$5ab94df7ac192afc = ()=>"functionB";

where $3bJ5v$workspacea variable is declared and used to access functionA.

😯 Current Behavior

The output commonJS file for workspace-b is:

var $3bJ5v$workspacea = require("workspace-a");

function $parcel$export(e, n, v, s) {
  Object.defineProperty(e, n, {get: v, set: s, enumerable: true, configurable: true});
}

$parcel$export(module.exports, "functionB", () => $5d4f15474cde7d38$export$5ab94df7ac192afc);
$parcel$export(module.exports, "functionA", () => $5d4f15474cde7d38$re_export$functionA);

const $5d4f15474cde7d38$export$5ab94df7ac192afc = ()=>"functionB";

where $3bJ5v$workspacea variable is declared but not used and $5d4f15474cde7d38$re_export$functionA is undefined.

💁 Possible Solution

We have seen in another project they are using a patch to make everything working as expected. Is this patch going to be released in the next version?

💻 Code Sample

A repo with a basic set-up using a patch version.

@mischnic We're also having this problem with v2.10.3, would it be possible to reopen this issue? We're also applying the patch linked above, it seems to resolve the issue.
