Linking and using local UI module in react-native - reactjs

Question

Disclaimer; I am new to react & react-native. I've downloaded a UI module and am attempting to use it in my project. This is what the folder structure looks like:
├── myProject
│   ├── README.md
│   └── src
│   └── client
│   └── {actual react-native project}
└── react-native-ui-module
├── node_modules
├── package-lock.json
├── package.json
└── src
I've added react-native-ui-module to myProject/src/client/package.json like so:
"react-native-ui-module": "file:../../../react-native-ui-module",
From there, I've executed the following command:
$ npm install
$ react-native link
I can see the module in node_modules after the above steps.
I've expected to then use the module like so:
import { Button } from 'react-native-ui-module';
However, I'm getting an error that states that the Modulereact-native-ui-module` does not exist in the Haste module map. I've tried following the error message's suggestion, which is:
This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
Clear watchman watches: watchman watch-del-all.
Delete the node_modules folder: rm -rf node_modules && npm install.
Reset Metro Bundler cache: rm -rf /tmp/metro-bundler-cache-* or npm start -- --reset-cache.
Remove haste cache: rm -rf /tmp/haste-map-react-native-packager-*.
I've also tried using relative and absolute paths in the import statement. Is there a better way of importing and installing the module? And what other troubleshooting steps can I take to actually use the module?
Also, to clarify; this is a module that I've purchased and manually downloaded, so it's not available from npmjs.

Answer 1

The short thing you can do, considering your current situation, is to copy the ui module into the node_modules of your {actual react-native project}, then the ui module will be available for you to use in the imports, in this way you don't even need to add the module into your package.json, but this way is just for testing what the ui module can do.
The correct way is to find this ui module in the npm site, and use the command npm install --save [name-of-the-ui-module], then ui module will be available for you to use in your imports.
(Updated considering comments bellow)
To avoid Headaches with npm, considering that your library is not in the npm repository, you can also include this library in a lib folder into your project, and use it like you were using any other component.
