react 16 shows error "Cannot read property 'number' of undefined"

when I upgrade react version to v16.2，console shows error "Cannot read property 'number' of undefined"，my react-imageview version is 1.2.1, I look into the source code, find that PropTypes is not import from "prop-types", maybe PropTypes cause the error? and how I solve the problem?
