Cannot run tests - sander seems to have multiple exports with the same name

[teehemkay]

I just cloned the repo and then > npm i and got the following error message.

> sander@0.5.1 build:cjs /Users/kmabonzo/Hacking/js/sander
> rollup -c -f cjs -o dist/sander.cjs.js

A module cannot have multiple exports with the same name ('createReadStream')
Error: A module cannot have multiple exports with the same name ('createReadStream')
    at /Users/kmabonzo/Hacking/js/sander/node_modules/rollup/src/Module.js:83:13

Searching the source code, I found the following:

/Users/tmk/Hacking/js/sander/src/sander.js:
    7  export const chmod = asyncMethod( 'chmod' );
    8  export const chown = asyncMethod( 'chown' );
    9: export const createReadStream = asyncMethod( 'createReadStream' );
   10  export const createWriteStream = asyncMethod( 'createWriteStream' );
   11  export const lchmod = asyncMethod( 'lchmod' );
   ..
   62  
   63  // special methods
   64: export { createReadStream, createWriteStream } from './specialMethods/createReadStream-createWriteStream'; // TODO aren't these covered by the standard methods?

FYIW I'm trying to debug gobblejs/gobble#89
