when running "npm install react-native-fs" the older version 1.3 will be installed. Also when applying a specific version with "@1.4.0"
Unfortunatly the 1.3 isn't compatible with Cocoapods 1.0.0 due to missing parameters in Podspec-file ("authors" and "summary"), which is already fixed in 1.4
This is what i get after the install-commands listed above:

What goes wrong there with "npm install"?
$ npm -v
3.8.9
$ pod --version
1.0.0
Same situation here. Master has the changes needed for using cocoapods.
This should have been resolved with the latest version (1.5)
