Error: 'homedir' is not exported by polyfill-node.os.js, imported by src/constant.ts

I'm using 0.9.0 and seeing this error when I bundle.
~~~ts
2: import { homedir as homeDir } from 'os';

homedir is a function that returns the string path of the current user's home directory.

I'd like to submit a PR to resolve this problem soon.
