What is the current behavior?
When upgrading Yarn from 0.17.0 to 0.17.6, I get this error upon running Yarn:

Error: ENOENT: no such file or directory, open '/Users/adam/.nvm/versions/node/v6.9.1/lib/node_modules/yarn/node_modules/bl/node_modules/readable-stream/duple
x.js'

If the current behavior is a bug, please provide the steps to reproduce.

Upgrade Yarn, run any yarn command.

What is the expected behavior?

It should not error.

Please mention your node.js, yarn and operating system version.

Node 6.9.1
Yarn 0.17.6
macOS 10.12.1

After further investigation, I was able to determine this had to do with the roadrunner package (https://github.com/kittens/roadrunner).

It seems that roadrunner.json had an out of date package cache. Upon deleting the roadrunner.json file, Yarn began working as expected.

I think this should stay open, however, as this broke on all of my coworkers machines upon our upgrade of Yarn, + it also broke on our CI machines.
