Can't push to Heroku because of DOTENV uninitialized constant error

问题

I am trying to push my project up to Heroku. I have been using:

    gem 'dotenv-rails', :groups => [:development, :test]

Because I am using recpatcha and need to export my keys to the app in development.

When I try to push the code to heroku I noticed this error message:

    remote:  !     NameError: uninitialized constant Dotenv

So I commented out the Dotenv gem and any Dotenv variables in the app. I ran

    $ bundle exec rake -P

Then tried the push again. I am still getting the same error from Heroku. Do I need to reset my gemfiles somehow?

回答1:

Ok, so the answer in the end was that I needed to change

    gem 'dotenv-rails', :groups => [:development, :test]

to

    gem 'dotenv-rails', :require => 'dotenv/rails-now'

which I think is another way of doing what you were suggesting there @ABPrime. Thanks a lot for your help.
