"react-native-fs": "^2.0.1" Dependency

[oximer]

Are you guys having trouble with this dependency?

"react-native-fs": "^2.0.1",

npm ERR! No compatible version found: react-native-fs@^2.0.1
npm ERR! Valid install targets:
npm ERR! 2.0.1-rc.2, 2.0.1-rc.1, 1.5.1, 1.5.0, 1.4.0, 1.3.0, 1.2.0, 1.1.0, 1.0.0, 0.4.0, 0.3.4, 0.3.3, 0.3.2, 0.3.1, 0.3.0, 0.2.0, 0.1.0
npm ERR!

I'm having the error above.
The version '2.0.1-rc.2' doesn't satisfy the requirements.
