Missing required arguments: aws_access_key_id, aws_secret_access_key

Question

I am currently trying to run my test suite in terminal but i get the following error:

Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)

I am using Carrierwave in my project and I am pretty sure that is what is causing the issue. here is my config/initializers/carrierwave.rb:

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',                       
    :aws_access_key_id      => ENV['S3_ACCESS_KEY_ID'],                        
    :aws_secret_access_key  => ENV['S3_SECRET_ACCESS_KEY']
  }
  config.fog_directory  = 'my_directory'                    

end

Here is my log:

What do I need to do to get rid of this error and run my tests?

Answer 1

You need to set the environment variables S3_ACCESS_KEY_ID and S3_SECRET_ACCESS_KEY so that they are available in Rails. You can do this in the terminal:

export S3_ACCESS_KEY_ID=<your access key id>
export S3_SECRET_ACCESS_KEY=<your secret access key>

Add those to your .bashrc or .bash_profile so they persist next time you start a new shell or use something like dotenv to make them specific to your project.

Answer 2

Apart from the obvious solution, that is setting the proper ENV VARS, one other problem, that i ran into was spring. I had the ENV vars set correctly, but they were just not recognized by the carrierwave.rb initializer. Since spring is used to preload the application and also processes like rake and rspec it didn't take into account the newly created ENV VARS. Restarting spring fixed that.
