Build Error: three fails to build

[mrdoob]

Package name

https://bundlephobia.com/package/three

Entire (stringified) error that I see in my browser console

"Failed to build this package."

I suspect it is because we tried using private class fields.

Highly likely. The gist of it is that bundlephobia compiles your code with Webpack 4 which is using an older version of acorn that cannot parse the newer JavaScript syntaxes (nullish coalescing, optional chaining, top-level await and export ns from...).

In this case, bundlephobia tools will need an upgrade. See: https://github.com/pastelsky/bundlephobia/issues/413#issuecomment-829240176
