I was trying to run "rails s" to run my server then I suddenly run into an error that says webpacker configuration not found. 

Here's the info:

```
boot@noki-K54C:~/Desktop/app$ rails s
=&gt; Booting Puma
=&gt; Rails 6.0.0 application starting in development 
=&gt; Run `rails server --help` for more startup options
RAILS_ENV=development environment is not defined in config/webpacker.yml, falling back to production environment

I already check the version of rails and its 6.0.0 my ruby version is 2.6.0.

Tried to search the web and try a few solutions but did not work out for me. 

Any idea what am I missing?
