error: package cn.touna.reactnativersautil does not exist

[SagiUziel]

I tried to install react-native-rsa-util like this:

npm i react-native-rsa-util
rnpm link react-native-rsa-util

After the installation I run react-native run-android and I got this error:

:app:processDebugResources UP-TO-DATE
