Vue + Babel: "Unexpected Situation Arose"

[Brandon Davis]

#302 appears to be similar to what I am experiencing, but the patron of that issue didn't really share how it was resolved.

Steps to reproduce:

1. Clone the rollup branch of https://github.com/girder/girder_web_components/tree/rollup
2. yarn
3. yarn rollup

Please note that I am attempting to convert a large webpack project to rollup, so I don't expect that, if this issue is fixed, the build will succeed. It's a slog.

I've tried switching node versions with n. Nothing I have in the 8-12 range made a difference.

Important files

import vue from 'rollup-plugin-vue';
import replace from 'rollup-plugin-replace';
import resolve from 'rollup-plugin-node-resolve';
import babel from 'rollup-plugin-babel';
import scss from 'rollup-plugin-scss';
import stylus from 'rollup-plugin-stylus-compiler';
import commonjs from 'rollup-plugin-commonjs';
// import postcss from 'rollup-plugin-postcss';

const plugins = [
  stylus(),
  scss(),
  commonjs(),
  vue({ css: false }),
  replace({
    'process.env.NODE_ENV': JSON.stringify('production')
  }),
  resolve(),
  babel({
    exclude: 'node_modules/**',
  }),
];

const config = {
  input: 'src/index.js',
  output: {
    file: 'dist/gwc.js',
    format: 'esm',
    sourcemap: false,
  },
  plugins,
};

export default config;

You have removed the branch containing a repro case so I can't quite take a look at this now. Going to close this issue as I'm not sure if you are still interested in this, but if you are - then feel free to reopen with the repro case and I'll get back to you (and I promise it will be way sooner than the last time).
