Error with esprima.js

[Sheraff]

Some error I'm getting when simply running standard-format in a folder.

/usr/local/lib/node_modules/standard-format/node_modules/esformatter/node_modules/rocambole/node_modules/esprima/esprima.js:5283
            throw e;

Can you file this on the standard-format repo? https://github.com/maxogden/standard-format

Also, please share the contents of the file that it's failing in, since that's probably relevant.
