Set up react-native-webrtc fail: "ERROR: The modules ['WebRTCModule', 'react-native-webrtc'] point to the same directory in the file system. Each module must have a unique path."

“ERROR: The modules [‘WebRTCModule’, ‘react-native-webrtc’] point to the same directory in the file system.
Each module must have a unique path.”

I’m newbie in webrtc. I set up follow readme in github but get this error in android studio:
(node 10.17, react-native-0.61.2, react-native-webrtc 1.75.3)

When I set up follow the same thing with this example, https://github.com/DimitrisTzimikas/RCTWebRTCDemo2 add react-native-webrtc lower version, that error is still there.

Sorry my english, please help me.

Why my WebRTC has 2 .iml file and can not delete one. android studio auto generate them when syncing.

I close my issue in here and finally get react-native-webrtc work.
