TypeError: Cannot create property 'context' on string

Hi there

I have the following setup in place on a project running on node 7.2.1 and npm 3.10.10.

{
  "scripts": {
    "lint:js": "semistandard",
    "lint:fix": "semistandard --fix",
    "lint:staged": "lint-staged",
  },
  "lint-staged": {
    "*.{js,jsx}": "lint:js"
  },
  "pre-commit": {
    "run": "lint:staged",
    "colors": true,
    "silent": true
  },
  "devDependencies": {
    "lint-staged": "^3.2.3",
    "pre-commit": "^1.2.2",
    "semistandard": "^9.2.1",
  }
}

All is okay here:

$ npm run lint:js

> example@0.0.0 lint:js /Users/mberridge/Sites/example
> semistandard | snazzy

semistandard: Semicolons For All! (https://github.com/Flet/semistandard)

/Users/mberridge/Sites/example/src/index.js
  9:1  error  Parsing error: Unexpected token

✖ 1 problem

But running npm run lint:staged returns an error wrapped around the output:

$ npm run lint:staged

> example@0.0.0 lint:staged /Users/mberridge/Sites/example
> lint-staged

 ❯ Running tasks for *.{js,jsx}

Not the end of the world, as it's still linting and working with pre-commit too.
But have I done something wrong to cause the error?

Any help appreciated, thanks all!

I made a test project for this issue: https://github.com/ai/sort-staged-example

Just add CSS properties order and commit it:

> sort-staged-example@ precommit /home/ai/Dev/sort-staged-example/front
> lint-staged

 ❯ Running tasks for *.css
   ✔ stylelint
   ✖ postcss/sort
     cd .. && git add
{ TypeError: Cannot create property 'context' on string '
🚫 postcss/sort found some errors. Please fix them and try committing again.

If I will run postcss/sort manually everything will works:

cd front
./postcss/sort -- test.css

This is a bug in SamVerschueren/listr#41. I'll wait till it is fixed and will update dependencies.
