Have to keep re-installing, plus jest warnings

Occasionally (I haven’t tied down the exact circumstances yet) I get compilation errors suggesting this module is not installed, so I have to install it again. It is registered like this in package.json, because I need v3: "react-native-document-picker": "git://github.com/Elyx0/react-native-document-picker.git#v3", (I’ve followed the instructions documented in https://github.com/Elyx0/react-native-document-picker/issues/94)

Also, in running jest tests I’m seeing this warning, I’m not sure if it’s the same problem as above or different: RNDocumentPicker Native module is not available, make sure you have finished the installation process and rebuilt your app

Also, running jest with --detectOpenHandles is showing this:

Jest has detected the following 1 open handle potentially keeping Jest from exiting:
  ●  TIMERWRAP
      at Object.<anonymous> (node_modules/react-native-document-picker/index.js:7:3)

In case it helps someone else: I worked around this issue by not import-ing the library, and instead require-ing it just before the code that will actually invoke it. Like this:

    const DocumentPicker = require('react-native-document-picker').default;
    /* ... */ await DocumentPicker.pick( // ...

It’d still be good for that to not be necessary.

Adding this mock in the jest.setup.js file fixed the warning for me.

jest.mock('react-native-document-picker', () => ({ default: jest.fn(), }));
