Undefined is not an object (evaluating 'RNSqlite2.exec')

Hi,

I have the following code but when app starts, an error is thrown.

undefined is not an object (evaluating 'RNSqlite2.exec')

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 localDB = new PouchDB("mydb.db", { adapter: "react-native-sqlite" });

Dependencies

 "pouchdb-adapter-react-native-sqlite": "^1.0.3",
    "pouchdb-find": "^6.4.3",
    "pouchdb-react-native": "^6.4.0",
    "react": "16.3.0-alpha.1",
    "react-native": "^0.54.2",
    "react-native-action-button": "^2.8.4",
    "react-native-deprecated-custom-components": "^0.1.2",
    "react-native-sqlite-2": "^1.5.2",
    "react-navigation": "^1.5.8"

If I change the line

const localDB = new PouchDB("mydb.db", { adapter: "react-native-sqlite" });

to

const localDB = new PouchDB("myDB");

It works.

Any ideas what could be the issue.

Thank you

Running the react-native link pouchdb-adapter-react-native-sqlite has solved the issue.

And thanks for the module. Great to see the speed boost.

For me, manually linking the package in the podfile fixes the issue
