"yarn dev" and "yarn release" fail

[iwittkau]

After #17 I tried some yarn commands: First, yarn install

$ yarn install
yarn install v1.3.2

I removed all 283 lines containing Dropping unreachable code etc. to shorten the log from yarn release.

I cannot reproduce this issue.

Which node.js version are you running? I think you just need to upgrade your node.js

Node 6 & 7 are currently not supported, updating to node 8 or 9 would fix it
