问题
I keep getting this error whenever I am trying to start the server validate_options': Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError) I can't seem to solve the issue! I am almost sure that the issue is caused Carrierwave and fog gems to use amazon s3. But I am not sure exactly in which folder the issue is!
Here's my initializer/carrierwave.rb:
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => ENV["S3_ACCESS_KEY"], # required
:aws_secret_access_key => ENV["S3_SECRET_KEY"] # required
}
config.fog_directory = ENV["S3_BUCKET"] # required
end
here's my log:
=> Booting WEBrick
=> Rails 4.2.5 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

My Bug
I had a the exact same error: validate_options': Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError) but my problem was that I created the bucket with name mycompany.bucket which is not allowed and gave me lots some trouble to find out. You can't use dots in a bucket name. For more information visit:
Bucket Restrictions and Limitations - Amazon Simple Storage Service https://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html
Suggestion
Now, I personally avoid the secrets.yml approach. I suggest using fog for production and file storage for development. For example:
photo_uploader.rb
class PhotoUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
process resize_to_fill: [100, 100]
# Choose what kind of storage to use for this uploader:
if Rails.env.production?
storage :fog
else
storage :file
end
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Add a white list of extensions which are allowed to be uploaded.
def extension_whitelist
%w[jpg jpeg gif png]
end
end
Gemfile
group :production do
gem 'fog', '1.42'
end
carrierwave.rb
if Rails.env.production?
CarrierWave.configure do |config|
config.fog_provider = 'fog/aws'
config.fog_credentials = {
provider: 'AWS',
aws_access_key_id: ENV["S3_ACCESS_KEY"],
aws_secret_access_key: ENV["S3_SECRET_KEY"],
}
config.fog_directory = ENV["S3_BUCKET"]
end
end
Environment Variables
If you still want to manage your environmental variables, maybe this can come in handy:
Temporary:
export S3_ACCESS_KEY=[...]
export S3_SECRET_KEY=[...]
export S3_BUCKET=[...]
After setting them you can print them to check if they got set:
printenv
You can also unset the variables:
unset S3_ACCESS_KEY
unset S3_SECRET_KEY
unset S3_BUCKET
Permanent:
Edit the ~/.bashrc or ~/.bash_profile to set the environmental variables permanently.
Hope this helps, have a great day!

Declare your AWS credentials in one of your yml file (secrets.yml for example) like this:
AWS_ACCESS_KEY_ID: XXXXXXXXXXXXXXXXXXXX
AWS_SECRET_ACCESS_KEY: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
ARTIFACTS_REGION: eu-central-1
ARTIFACTS_BUCKET: some_bucket
Don't forget to add the file with your credentials to .gitignore
Then use your credentials in the carrierwave config file (carrierwave.rb) like this:
config.fog_credentials = {
provider: 'AWS',
aws_access_key_id: ENV['AWS_ACCESS_KEY_ID'],
aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
region: ENV['ARTIFACTS_REGION']
}
UPDATED
To manage your environment variables easier try Figaro gem. Maybe it'll expose your actual problem and you'll solve it.
回答3:
Usually this results from either the values not being set in env, or accidentally being mis-spelled.
There are a few possible ways to manage this, but in development the most direct way is with export, like this:
export S3_ACCESS_KEY=[...]
If you fill in the [...] portion with your value (and repeat for the three distinct variables), it should be able to find everything.
You can also check the current values of these by using echo like this:
echo $S3_ACCESS_KEY
If you have set the value correctly, it should print the value to your terminal. If the value is not set, it will just print an empty line (if there is an empty line for any of the values, it would result in the error you are seeing).
