[mulfyx]

• Rollup Version: 1.19.4
• Operating System (or Browser): Ubuntu 18.04.2 LTS on Windows 10 x86_64
• Node Version: v12.9.0

How Do We Reproduce?

import { join as pathJoin } from 'path';

export default async function createConfig() {
  const rootPkg = await import(pathJoin(__dirname, 'package.json'));

  console.log(rootPkg);
}

Expected Behavior

console.log displays package.json

Actual Behavior

ReferenceError: pathJoin is not defined

[mulfyx]

if write

import { join as pathJoin } from 'path';

export default async function createConfig() {
  const pkgPath = pathJoin(__dirname, 'package.json');

  const rootPkg = await import(pkgPath);

  console.log(rootPkg);
}

it works

Thanks, this is definitely a bug. Pasting this into the REPL, we see that inside the dynamic import, pathJoin is not replaced with path.join as it should, here a slightly modified version highlighting the difference: https://rollupjs.org/repl/?version=1.20.0&shareable=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
