Unexpected linter output

[nikmash]

I try to run semistandard and I hit this error:

semistandard: Unexpected linter output:

It's odd because it works fine on another machine of mine. Any insight on what exactly is going on here?

Unsure on this, sorry. Were you able to get past this? Have you tried reinstalling the latest version?

Same here.

 ~/D/g/flux-app  cat node_modules/semistandard/package.json | grep version
  "version": "7.0.2",

@Flet still hitting the error. Ended up just using eslint.

[Flet]

:(

Does standard blow up too?

[Flet]

Also, are you using the react plugin with eslint? May be worth trying to use it to see... Looks like the stack trace is pointing to it... eslint-plugin-react/lib/rules/prop-types.js:450:27

@nikmash if you could try and isolate the code that would be helpful.
Its likely this is a problem with 1 particular rule in eslint dying on the code you provided.
