Unable to resolve module

Question

I have a react-native app with a homemade library but it appears every time this error and I don't know what to do with this. If someone needs more code, tell me and I will include it because I don't know if you need more code to resolve it.

I already made that this error tells me, delete node_modules and cache and reinstall, but it doesn't work.

error: bundling failed: Error: Unable to resolve module `react-native-silent-ping-sms` from `C:\Users\erikc\Flyve\proyecto1\index.js`: Module `react-native-silent-ping-sms` does not exist in the Haste module map

This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
  1. Clear watchman watches: `watchman watch-del-all`.
  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
  3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

Answer 1

The error means the module react-native-silent-ping-sms is either not installed or not linked using react-native link .

First, try doing

watchman watch-del-all && rm -rf $TMPDIR/react-* && rm -rf node_modules && npm install && npm cache clean --force

Or you can do the above with one simple command, just install react-native-surrender globally using npm install -g react-native-surrender & then type surrender .

Then link react-native-silent-ping-sms using react-native link or react-native link react-native-silent-ping-sms

It should be resolved then :)

Answer 2

It was installed in the package.json and I try cleaning cache every time. So I decided to upload it to the NPM page and install the library directly from the NPM page and it works perfectly.
