Error adding react ignite elements

[eurigilberto]

After I write ignite add elements this happens:
× ignite-elements was not able to be installed. Is it a valid NPM module?

Command failed: yarn add ignite-elements --dev
error An unexpected error occurred: "EISDIR: illegal operation on a directory, open 'C:\Users\Euri Herasme\AppData\Local\Yarn\cache\v1\npm-babel-preset-react-native-0.0.0-7f8fe323-a9ae-44cd-aaeb-b7b34471e143-1499175525696'".
