I would try running the same command on a newer version of node 9. There have been bugs around accessing files in that node version.

Thank you for your reply, rizowski! Just checked, the same exception is thrown on latest node v9.11.1 as well :(

@XuYan Is this still an issue? I noticed that it was being ran in the Windows linux subsystem. Which microsoft has recently changed quite a bit around file system permissions by passing along metadata on mount.

Closing this for now. If this is still an issue I am willing to reopen to discuss.
