I down version from 2.0.1 to 1.7.4 fix it Thanks lots

[darrachequesne]

I think that is linked to socketio/engine.io-client#562, but it shouldn't throw an error.

=> facebook/react-native#13991

@wangzhiqiang1975 I down the version also works for me. Thanks

But io.connect(url, { transports: ['websocket'] }); use this maybe better

Adding { transports: ['websocket'] } works for me as well.
