A module cannot import itself

[danielkcz]

First I got a same error as #1 so I also installed master version of commonjs and now I am getting this strange error.

A module cannot import itself (D:\workspace\stampit\node_modules\rollup-plugin-node-globals\src\global.js)
Error: A module cannot import itself (D:\workspace\stampit\node_modules\rollup-plugin-node-globals\src\global.js)

Essentially I am trying to create bundle of unit tests so they can be run in a browser. This is whole config I am using...

import babel from 'rollup-plugin-babel';
import nodeResolve from 'rollup-plugin-node-resolve';
import commonJs from 'rollup-plugin-commonjs';
import json from 'rollup-plugin-json';
import nodeGlobals from 'rollup-plugin-node-globals';
import nodeBuiltins from 'rollup-plugin-node-builtins';

export default {
  entry: 'test/basics.js',
  format: 'iife',
  dest: 'testBundle.js',
  plugins: [
    nodeBuiltins(),
    nodeResolve({ jsnext: true, main: true, browser: true }),
    commonJs({ ignoreGlobal: true }),
    nodeGlobals(),
    json(),
    babel({
      babelrc: false,
      exclude: 'node_modules/**',
      presets: ['es2015-rollup', 'stage-1'],
      plugins: ['transform-runtime'],
      runtimeHelpers: true
    }),
  ]
};

It's on Node v6.2.0.

yeah I don't think it likes the run time

[danielkcz]

Well I don't think that's the case. I tried to disable while babel plugin and error stays the same. It makes sense because of exclude: 'node_modules/**', so it shouldn't run this rollup plugin through babel at all. What else could it be?

Disabling nodeGlobals plugin I am getting this output:

Treating 'fs' as external dependency
Treating 'module' as external dependency
Treating 'fs' as external dependency
Treating 'fs' as external dependency
Error parsing D:\workspace\stampit\node_modules\rollup-plugin-node-builtins\src\es6\util.js: 'import' and 'export' may only appear at the top level (24:0) in D:\workspace\stampit\node_modules\rollup-plugin-node-builtins\src\es6\util.js

For the reference actual test file contains just one simple test and import of ava test runner. I know there are some talks it doesn't work well, but I was hoping this might solve it since ava just needs bunch of node related stuff.

[calvinmetcalf]

ok see this comment of the required steps to get them all working together

[barneycarroll]

I had difficulties with a lot of tooling in node 6 so rolled back to LTS. I'm getting this on node 4.4.5.

[calvinmetcalf]

@barneycarroll can you be a bit more specific ?

[barneycarroll]

Sorry @calvinmetcalf, I appreciate that's not a very helpful bug report :)

I only encountered this bug in trying to help out a friend with their rollup import of browserify-assuming UMD packages, and encountered this on Windows 7. This was not the bug they were seeing :) I will get back to you tomorrow on this.

[calvinmetcalf]

also woops I was getting this one confused with a different issue, I'm going to look into this, looks like the 'global' file can accedentally try to import itself

[calvinmetcalf]

ok I should be able to add the global and buffer files to the exclude list for this so it doesn't run on them

done in 1.0.6
