CI_ENVIROMENT not working

I'm using the new alpha 2, and I set the CI_ENVIROMENT to development in the .env and public/.htaccess and I still get the 'Whoops' message and not whats wrong on my code.
Do I have to change anything else to let codeigniter show me the errors

I just configure this in my .env file and don't change anything in the public/.htaccess

Code:

CI_ENVIRONMENT = development
app.baseURL = 'http://myapplication.test/

I did notice that both in your subject and your comment you state CI_ENVIROMENT which is incorrect it is CI_ENVIRONMENT
Also make sure that your env file is moved to .env as codeigniter supplies you with an env file as a template but needs to be copied / moved to .env

Hope this helps.
