Using Capistrano and error occurs during execution of cap deploy

198 views Asked by At

I'm using Capistrano to help deploy a Rails project and when I run the command cap deploy I get the following error produced below. Anyone have an idea what's going wrong?

Here is the error that is being generated when it's trying to execute the command.

Edit: Here's what's in redis.rb

$redis = Redis.new(host: 'localhost', port: 6379, driver: :hiredis)
class << $redis

  def get_json_list(key)
    str = "[" <<  $redis.lrange(key, 0, -1).join(',') << "]"
    JSON.parse(str)
  end

end

Edit 2:

The issue was that it was somehow running the wrong version of Ruby and from the error we can see that it says 1.8. So I had to make sure my system defaulted to 1.9.3 and voila! No more syntax error and it was able to run fine.

This is a shot in the dark. I would also verify that the environment that you are deploying this app to is using the same version of ruby and rails.

I was getting all kinds of syntax errors when I deployed my last app and went about crazy until I realized I hadn't adjusted my rvm.

This is not an error because of Faraday. It's a syntax error in your initializer as this line indicates:

*** [err :: 54.215.187.53] /var/www/crowdcode/releases/20130831210643/config/initializers/redis.rb:1: syntax error, unexpected ':', expecting ')'

You want to check config/initializers/redis.rb for any syntax errors.
