I'm trying to create a simple React module. My project structure looks like this :

```
project
|---src
     |---Login.js
     |---login.css
     |---index.js
...

```

I have used `create-react-app` boilerplate.

Now when I have published the repo, it gives me :
**Could not find module in path: 'react-mua-login' relative to '/src/index.js'**

What is the problem actually ?

* Repo : <https://github.com/maifeeulasad/react-mua-login>
* npm package name : react-mua-login
* codesandbox : <https://codesandbox.io/s/react-mua-login-sample-x12dr?file=/src/index.js>
