prop-types problem in radium

[Mohammad-Eslahi-Sani]

Hi.
After installing react-timekeeper@^1.0.0 I face this prop-types error in radium package:

TypeError: Cannot read property 'object' of undefined
./node_modules/radium/lib/components/style.js
E:/Gandom/Karpage/Admin/node_modules/radium/lib/components/style.js:123

  120 | 
  121 |   return Style;
  122 | }(_react.PureComponent), _class.propTypes = {
> 123 |   radiumConfig: _react.PropTypes.object,
  124 |   rules: _react.PropTypes.object,
  125 |   scopeSelector: _react.PropTypes.string
  126 | }, _class.contextTypes = {

and here is the block of timekeeper in package-lock.json:

"react-timekeeper": {
      "version": "1.0.0",
      "resolved": "https://registry.npmjs.org/react-timekeeper/-/react-timekeeper-1.0.0.tgz",
      "integrity": "sha1-DdigYwnubgSY9DUAShKGFxn4ePw=",
      "requires": {
        "lodash": "^4.17.4",
        "radium": "^0.18.1",
        "react-motion": "^0.4.7"
      }
    },

I tried different versions of prop-types and radium base on their change logs but the error is not solved. so any idea how to solve it?

react: 16.5.2
react-timekeeper: 1.0.0
