Using javascript generated package with React result in error during react build

Description

I am trying to use a javascript package, generated through swagger editor, in a react application and i get the following error :

"Cannot find module: 'ApiClient'. Make sure this package is installed."

the error is generated when react builds the sr/index.js file of the package.

the package works fine when used with browserify.

Swagger-codegen version

The version used is the one used by swagger-editor latest release : 2.4.15

Swagger declaration file content or url

The yaml content does not trigger a code generation error. Only the generated code does not seem to be compatible with react

Command line used for generation

Generated through swagger-editor

Steps to reproduce

Generate any package and try to bundle in a react aplpication

Start with the generated src/index.js package entry point and compare how it is bundled by React with how the same package works through browserify. Reproduce using a package generated through Swagger Editor with swagger-codegen 2.4.15, then identify what causes React's build to report that it cannot find ApiClient. Done means the generated package builds successfully in a React application.
