I'm randomly getting the following error message. Does anyone have any ideas what could be causing this?

The last place Spree is hit before calling redis-rb:
unless (val = #cache.read(key)).nil?
return val
end
where #cache = Rails.cache
UPDATE
I am using this gem with this SSL plugin, so the error may be related to the plugin.
The error happens when line = #sock.gets is nil. Here's the locals right after that is determined to be true.
[1] pry(#<Redis::Connection::Ruby>)> line

This looks like this could be an issue with the ruby redis client.
You could try downgrading a version and/or filing an issue for the redis team in the Github repository.

Tasks: TOP => db:migrate
Error emerging at Object.create... stage, what is wrong?
Update: In a comment it was pointed out that the actual code was not containing "Object", this answer is thus based on the wrong example.
Object is a bad name to use for an (unscoped) Model class, as it is already defined by Ruby.
The Object you are calling create on is probably not the Object class you defined in your model sources.
I assume you run rails. Remove the Object.create lines from your migration. Run it, it should work fine. Then, call rails console, where you end up in a live session. Here you can play around with your code, e.g. call Object.create, Object.where{id: 1} etc. I assume that you will get the same errors.
So, as a solution, rename your Object into something else, like Class and look if it works.
Okay, that was a joke, of course Class is also a really bad name for a model class :) . Try to find something more meaningful.
The problem was solved by set up pg gem, which pull bundle of another gems and packs (particularly postgresql-server-dev-all). After installing it, the command rake db:migrate works fine and completely.

Turns out a GEM conflict was the issue. I fixed the problem with the code from an indirectly related question that used Rails instead. Please see below:

I am new bee to twitter API and MongoDb. I am trying out a ruby example from the book 'MongoDb In Action', Chapter-3 which connects to Twitter and gets feeds based on given tags. I have done the ruby set up as suggested. I am getting the following exception, which I think is related to ruby set up. Any hint is highly appreciated.

The book you are reading was printed in 2011 and appears to use APIv1 which has recently been depreciated by twitter.

You'll need to set up oauth and I suggest you start with the twitter gem documentation.

I'm facing a Timeout::Error issue while loading heavy web page. I observed that even if I added an implicit wait call #driver.manage.timeouts.implicit_wait = 300, a timeout error is thrown before 300 seconds - it's thrown in around 60-70 seconds.
Error thrown is -

try using gem fakeweb
FakeWeb is a helper for faking web requests in Ruby. It works at a global level, without modifying code or writing extensive stubs.
In GEMFILE write
gem 'fakeweb', :require => false
require 'fakeweb'
use above statement in your file
Hope this would work..
I believe the original issue isn't with Selenium and your question is answered here:
'rescue in rbuf_fill': Timeout::Error (Timeout::Error)
I have a series of JSON messages that I need to process and I've run into some trouble with character encodings. I retrieve this message from a RabbitMQ queue like so:
#data = []
#queue.pop do |metadata, payload|
parsed_message = JSON.parse(payload)
#data << parsed_message
end
I then process them using Resque and enqueue them like so:
Resque.enqueue(Worker, #data)
When I run the worker it throws this error:

I've wrapped all the code in the perform function from the worker in a begin/rescue block, to try to catch the exception but to no avail which leads me to think that it's from inside Resque somewhere.
I've tried enqueueing the Resque worker with the raw data and then parse it inside the worker into JSON and setting an UTF-8 encoding:
raw_data.each do |msg|
msg = msg.encode("UTF-8", :invalid => :replace, :undef => :replace, :replace => "")
parsed_msg = JSON.parse(msg) rescue nil
next if parsed_msg.nil?
parsed_data << parsed_msg
end
and I still get the same error.
It's not always the same character, sometimes it's \xC2 or \xD8 if I remember correctly
Any ideas?
Is it possible the file encoding is incorrect?
Try inserting:
# encoding: UTF-8
at the top of the relevant ruby source files. This is one of the most obnoxious things in Ruby 1.9.
