TypeError: Cannot read property 'exec' of undefined

[Chris Ian Fiel]

This is my code but I got the error TypeError: Cannot read property 'exec' of undefined. Any idea?

import PouchDB from 'pouchdb-react-native'
import SQLite from 'react-native-sqlite-2'
import SQLiteAdapterFactory from 'pouchdb-adapter-react-native-sqlite'

const SQLiteAdapter = SQLiteAdapterFactory(SQLite)
PouchDB.plugin(SQLiteAdapter)
const db = new PouchDB('mydb.db', {adapter: 'react-native-sqlite'});
db.get('4711')
  .then(doc => console.log(doc))

Full Error:

It seems that SQLite module is not loaded correctly.
Set up react-native-sqlite-2 right way by following the instruction.

@craftzdog I check everything I followed the instruction. I am testing it using jest. Any Ideas? :)

[Takuya Matsuyama]

You can not run any native modules on jest. Because it doesn't provide iOS/Android environment.

I see. Thanks!
