Parcel: 🐛 bundle error in `1.3.0`: Cannot read property 'tokens' of undefined

[rwu823]

I got this error when upgrading to 1.3.0
node_modules/react-redux/es/index.js: Cannot read property 'tokens' of undefined

But it works great in 1.2.1

Reproduce Setup

entry.js

import 'react-redux'

$ parcel entry.js

I am seeing something similar with another package

index.html

<script src="../node_modules/material-design-lite/material.min.js"></script>

error

hmm, it seems to work for me. Can you run with --no-cache to see if something there is causing an issue? Otherwise, can you provide a test project that reproduces the issue? Thanks!

I try to create a minimal-project but now seeing a different build error?

Still get same errors with --no-cache

[Olian04]

I get a similar error with moment.js

[devongovett]

This is caused by files that are ignored by babel. In that case, babel doesn't return an ast. Should be fixed by 22478d3.

@devongovett Thanks for your work.
