Rollup-nested-dynamic-imports

Introduction

I created this repository to explain an issue between rollup 0.66 and rollup >= 1.

Reproduce the issue

First of all, clone and install these repository:

git clone https://github.com/jleveugle/rollup-nested-dynamic-imports.git
cd rollup-nested-dynamic-imports

Checkout the branch rollup-0.66 and install the project:

npm i

Try to build the project:

npm start

It should result to:

➜  rollup-nested-dynamic-imports git:(rollup-0.66) npm start

> rollup-nested-dynamic-imports@0.0.0 start /Users/jleveugle/Documents/Work/github/jleveugle/rollup-nested-dynamic-imports
> rollup -c


index.js → ./dist...
created ./dist in 19ms

You can test the project if you want, it should display "foobar":

➜  rollup-nested-dynamic-imports git:(rollup-0.66) ✗ node dist/index.js
foobar

Checkout the branch master, and launch an installation to install rollup@^1.1.0

npm i
npm start

The build should fail, with this kind of error:

➜  rollup-nested-dynamic-imports git:(master) npm start
$ rollup -c

index.js → ./dist...
