Issue with preinstall scripts

I have a preinstall script in my package.json:
```
"preinstall": "npm run checkversion",
"checkversion": "node ./internals/scripts/checkversion.js",
```

And when I run `quickfix push` I get the following error:
```
Error: Cannot find module '/private/tmp/quickfix/react-boilerplate/internals/scripts/checkversion.js'
```
