As you may know if you follow my blog. I develop on a Windows machine (and everyone hates me for that).
I received errors related to Capistrano and Psych which I know nothing about
/usr/local/lib/ruby/1.9.1/psych.rb:154:in `parse‘: (): couldn’t parse YAML at line 0 column 5 (Psych::SyntaxError)
from /usr/local/lib/ruby/1.9.1/psych.rb:154:in `parse_stream’
from /usr/local/lib/ruby/1.9.1/psych.rb:125:in `parse’
from /usr/local/lib/ruby/1.9.1/psych.rb:112:in `load’
So I have contacted cloud66 team, who advised it is an asset pipeline issue caused by upgrading to Rails 4. And they suggested to delete the manifest cache files (/var/deploy/tafqit-amesterdam/web_head/shared/assets/manifest*).
I logged in to my cloud66 dashboard where I have web console access to my server, I navigated in directories and deleted files as instructed and deployment went fine, now I have my site upgraded to Rails 4! What a joy!.
This was my first time where I had to navigate files on Ubuntu, but found out to be easy, simillar to DOS.
all Ubuntu console commands can be found here
