Old version of React-Date-Picker allows too new version of React-Calendar

I installed using: npm i react-date-picker@6.7.0

With react 15.5.4

When I try to do the simple example:

state = {
    date: new Date(),
  }

  onChange = date => this.setState({ date })

  render() {
    return (
        <DatePicker
          onChange={this.onChange}
          value={this.state.date}
        />
   }

I get this error in the console:

Hey there, it seems like the version of react-calendar got installed. Which is odd, because it means package-lock.json did not work properly 😦 Please try the following:

npm uninstall react-date-picker
npm install react-calendar@2.11.0
npm install react-date-picker@6.7.0

I think this will ensure the correct version of dependencies is installed.

@buddythumbs are you sure everything installed correctly, both of the packages appear in your package.json?? Perhaps you could try deleting your package-lock.json and your node_modules folder and then running npm install
