I'm creating an app using react native but some imports raise the error from the title: "Unknown named module"
. This happens with two packages, react-native-material-design
and react-native-db-models
, so I suspect the problem isn't on the modules but in my setup.
I tried linking the packages with react-native link
and repackaging the app using react-native run-android
, but none of these solved this issue. I've looked up examples of imports on github, and even copying working code raises the same error.
I tried installing the modules using either yarn and npm. I tried with relative paths like ../../react-native-db-models
. Didn't work!
This is how I import the modules:
import RNDBModel from 'react-native-db-models';
import { List, Button, Toolbar, } from 'react-native-material-design';
These are my project dependencies:
"dependencies": {
"react": "15.4.1",
"react-native": "0.39.2",
"react-native-db-models": "^0.1.3",
"react-native-material-design": "^0.3.7",
"react-native-md-textinput": "^2.0.4",
"react-native-vector-icons": "0.8.5",
"react-redux": "^5.0.1",
"redux": "^3.6.0",
"redux-logger": "^2.7.4"
},
If React/React Native is incompatible with these modules, how do I figure out which version should I use? Maybe the error has nothing to do with imports and has something to do with my project?
The package server started by
react-native start
seems to have a cache of the node modules. Stopping and restarting the server solved the issue.Always restart your react server after installing modules!
