Sketch 44
_I am..._ attempting to run `npm run render` on the examples, using Sketch version 44. It fails with 

```Error while running the command after build```

`npm run build` and `npm run link-plugin` still appear to be working fine.

**Expected behavior:** `npm run render` to produce a Sketch file of rendered React components.

**Observed behavior:** ```*error* Error while running the command after build```

**How to reproduce:** 
1. Clone `react-sketchapp`
2. cd into the examples/foursquare-maps example. `npm install`
3. Run `npm run render`
4. Receive __error__ Error while running the command after build

**Sketch version:** 44 (new version as of this morning 5/18/2017)

**Please attach screenshots, a zip file of your project, and/or a link to your github project**
