问题
I am trying to RAILS_ENV=production run rake paperclip:refresh:thumbnails CLASS=Spree::Image
on my remote server in my current rails app directory, so I can refresh the spree images that I have uploaded in the past.
I am using S3, my bucket is setup correctly as I can see each of my product's images in individual ID folders in my AWS S3 bucket.
But each time I run the above command I get a 'No Such Key' Error when the rake is aborted.
This command runs locally and works fine. (obviously without the RAILS_ENV=production locally)

Ok so I wrote this question to answer it myself. I hope the question makes sense.
For clarity, I had this issue because it was old images (old non existing paths that were associated with an old S3 Key) that I had uploaded with another S3 Key in previous testing on the same rails app. I did this earlier while trying to get S3 to work with my Rails Spree Application.
What I did to solve this was go into my Rails console on my remote server with this command:
$RAILS_ENV=production rails c
I then ordered the list of all Spree:Images them with this:
$y Spree::Image.all(:order => 'attachment_updated_at')
The 'y' is a nice little yaml way of displaying the information of the Spree:Image that's a little more human.
Next I looked at the ID of each Image and noticed that there was a good amount of them with IDs that did not match folders in my AWS S3 bucket.
In my Case the lowest ID number that was in fact a folder in my S3 bucket was '1078' so I ran this:
$Spree::Image.where('id < ?', 1078).destroy_all
This deleted any Spree::Image that had an ID of 1077 or less.
Finally, I closed rails console and ran this on my remote server inside my current rails app directory. (In my case is was /home/deployer/apps/potentialapp/current/)
$RAILS_ENV=production rake paperclip:refresh:thumbnails CLASS=Spree::Image
This reformatted my uploaded images on Spree and everything is now working great.
Hope this saves someone a great big headache. (Oh and empty your cache when you go to test and see if the images have in fact reloaded, almost cried at 4 am last night.)

I solved the same problem using the console and skipping errors (old/broken S3 assets):
Spree::Image.all.each { |i| i.attachment.reprocess! rescue nil }
