undefined is not an object(evaluating 'react_PropTypes.oneOf')

[Balasnest]

I'm currently experiencing an issue with this.

undefined is not an object(evaluating 'react_PropTypes.oneOf')

Check this screenshot: http://prntscr.com/gyd6dl

version:
"react": "^16.0.0-rc.3",
"react-native": "^0.48.3",

How to resolve this?

same issue here. Anyone a idea?

Make sure you've updated this package to the latest version.

[vladbars]

the same issue
"react": "16.0.0",
"react-native": "^0.45.1",
"react-native-vector-icons": "^4.4.2"

Same issue after upgrading to react-native 0.49.5 and react 16.0.0-beta.5, with the latest version of the vector icons NPM package, same thing with master.

same here...

Same issue:

"react": "^16.1.1",
"react-native": "0.50.3",
"react-native-material-design": "^0.3.7",
"react-native-vector-icons": "^4.4.2",

[alfonso1003]

Same here.

"react": "^16.1.1",
"react-native": "0.50.3",
"react-native-material-design": "^0.3.7",
"react-native-vector-icons": "^4.4.2",

I researched this more, and it turns out that PropTypes has been taken out of the standard library, so React.PropTypes doesn't work anymore.

I grepped the react-native-vector-icons codebase and all the references to React.PropTypes have been updated. I think the issue is in another package, not this one. In my case, I'm seeing that react-native-material-design is still using React.PropTypes and has react-native-vector-icons as a dependency.

./node_modules/react-native-vector-icons/RNIMigration.js:    color: React.PropTypes.string,

I'm going to manually update the code there, and I'll report back if that worked or not.

[alfonso1003]

Update: I tried updating the code manually, but it's not written in React or ES6 and I could only guess at the syntax. I'm not a Javascript expert, obviously... I'm switching from react-native-material-design to react-native-elements instead, since it looks like the issue is cleared up there.

If you're using react-native-material-design, I brought what I found to their attention:
invertase/react-native-material-design#174

Seems like maybe you have another third party dependency which depends on an older version of RNVI. @alfonso1003: Your grep shows "react-native-vector-icons": "^2.0.1" which def is out of date.

Please confirm that the version in your node_modules folder is actually the latest version and that there's not multiple versions installed via third party deps.

I am also having this issue:
RNVI: 4.4.3 (confirmed in node modules)
React: 16.0.0
RN: 0.51.0
Prop-types: 15.6.0

Tried downgrading prop-types to match that in RNVI: ^15.5.10. This doesn't have any effect on the bug.

Can confirm that downgrading to [email protected] fixes the issue in debug as described here #443 (comment) (but I don't seem to be able to build an APK that works using the alpha!)

[Chris-Petty]

Fixed the issue for me as #588 (comment). Was using a another dependency that relied on [email protected], this was using React.Proptypes which is deprecated in React 16.

Closing this one too :-)
