It fails right after build with npm@5.3.0

Not sure if it helps. Here's the log:

Btw, it works great with node@6.11.2 (npm@3.10.10)!

I was seeing the same May not delete failure with 5.3.0, upgrading to 5.4.1 resolved the issue.

Great to know that 5.4.1 is a solution, I haven't had time to look into this yet. I'd like to support as many npm versions as possible so it's still on my to-do list!
