React-datepicker: DatePicker doesn't work with React 16.4

[spyx08]

Expected behavior

I already used Datepicker in a lot of different app and got no problems

Actual behavior

Now with React 16.4, when I try to render a normal DatePicker, app's crash.

render(){
<DatePicker selected={moment()} onChange={this.onChange} />
}

I got this error

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object

I tried with version 1.4.1 (who was working in a older app) and with 1.5.0 and no one is working.

doesn't work for me as well.. a problem with react-popper

This type of message usually indicates that you've imported the library improperly and ended up with something like { default: DatePicker } rather than just DatePicker. Maybe your tooling or build changed at the same time you upgraded React?

Yes i was thinking it was bad imported/builded but I tried to remove all my node_modules and to re-install them with yarn and npm but got the same issue.

But yes I expect an error with the import/build I don't know how I can check this...

More than half a year old. Anybody fix this problem? I have the same one. Yes, I am doing import Datepicker.

Just an update for anybody who stumbles upon this problem. I noticed the error was with popper and went over to their GitHub, where some people had the exact same issue and suggested making sure your react and react-dom are the same version. I tried that and had no luck. Then I stumbled upon another solution for a completely unrelated project but same error, where people suggested deleting your node_modules directory and starting over. It worked.

tl;dr: if you're getting this problem, it's probably because something is screwed up in your node_modules, which is causing a dependency of react-datepicker to fail. Delete the folder and install everything fresh.

ran into the same problem, I was updating datepicker from a legacy version of 1.2.7 to 2.7.0

after deleting the datepicker folder under node_modules and running npm install again, it fixed the issue
