"react-bootstrap-validation": "^0.1.11", not support with "react-bootstrap": "0.31.2",

I was able to get rid off this TypeError by downgrading 'react-bootstrap' to '^0.28.1' with the next steps:

• Change the 'react-bootstrap' version in node_modules/react-bootstrap-validation/package.json
• Make npm i in node_modules/react-bootstrap-validation
