Introduction

In this article, we will explore the issue of resolving the react-native-executorch module in a React Native app. The react-native-executorch library is used to run the Llama model inside a React Native app. However, when attempting to run the app, a module resolution error occurs. This error is caused by the missing expected entry file (index.js) inside the lib/commonjs/ directory of the react-native-executorch package.

Description

I attempted to run the Llama model inside my React Native app using the react-native-executorch library. I followed the setup instructions provided in the library's GitHub repository, but upon running the app, I encountered a module resolution error. The error message states:

While trying to resolve module react-native-executorch, the package was found, but the main module field could not be resolved (lib/commonjs/index.js does not exist).

This suggests that the expected entry file (index.js) is missing inside the lib/commonjs/ directory of the react-native-executorch package. As a result, the module fails to load when the application starts.

Steps Taken

To resolve this issue, I took the following steps:

Installed react-native-executorch using yarn add: I installed the react-native-executorch package using the following command:
```
yarn add react-native-executorch
```
Followed the official documentation and added necessary imports and model initialization code: I followed the official documentation and added the necessary imports and model initialization code to my React Native component.
Attempted to run the app using yarn start: I attempted to run the app using the following command:
