Moonshine Deployment Error - ruby-on-rails

When I try to deploy my rails app to Rackspace using Moonshine, I get the following error:

How should I go about fixing this?
If you don't know how to fix it, what are other gems that would help me deploy my app to Rackspace.


I found the issue. Capistrano was pulling the source from git and I forgot to push the new code. That means, application_manifest.rb didn't exist on the server. After pushing, it worked perfectly.

Error while deploying on a staging server

I just reinstalled my staging server and I can't deploy my code. I installed pgsql and libpq-dev on the Ubuntu server 16.04 that I use. The file /srv/outils/www/projectname/shared/bundle/ruby/2.3.0/gems/pg-0.21.0/lib/pg_ext.so do exist.
Here is the error I encounter :

*** [deploy:update_code] rolling back
I checked all I could think of. It's the same error if I do manually the capistrano commands in the server.

I was fixated on pg_est.so, but what I was missing was libruby.so.2.3
I uninstalled my ruby and reinstalled it, and now this step works.

Error with cap deploy:cold in Digital Ocean for Rails app

I really want to deploy an app and had been following railstutorial by Michael Hartl. Now, I'm about to deploy my first app in Digital Ocean but I keep on running on to a lot of problems. Anyway, most of it was already done except on this big one.
I followed the this blog by Hoang Pham and a tutorial by [Andrew Gertig][3].
Anyways, this is my first entry here. Let me say my thanks in advance.Everytime I do, $ cap deploy:cold, on my local machine I always get this error.

And I also notice this one, that's why I did gem uninstall bundler and gem install bundler again in the VPS

You've got a Cannot allocate memory error. That means not enough RAM for bundler on your deploying machine.
You can add swap partition to do this, or create a DO droplet with bigger RAM space.
Good tutorial about adding a swap to DO droplet https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-12-04

I had a similar problem trying to deploy Dokku on Digital Ocean / Ubuntu.
Easy fix with 3 lines of code run inside SSH session in the root digital ocean user:
dd if=/dev/zero of=/swapfile bs=1024 count=1024000
mkswap /swapfile
swapon /swapfile
For reference see: http://dev.housetrip.com/2014/07/06/deploy-rails-and-postgresql-app-to-dokku/

trying to deploy to DO with capistrano. got an error when cap deploy:cold

I am following this guide and got stuck at cap deploy:cold :

It seems like you're missing JavaScript runtime library. Install NodeJS on the server using this:
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs
Also, for rails deployments on DO and Ubuntu in general, this is a great resource for all the steps (and a video walkthrough):

it error happen when i migrate project from ruby 1.9.3 to ruby 2.0

You have to set GEM_HOME accordingly:
$ export GEM_HOME='/home/shibanov/.rvm/gems/ruby-2.0.0-p195'

Rails: how to debug assets:precompile failure on cap deploy

I'm getting a cryptic error on cap deploy
$ cap deploy
. . .
* executing "cd -- /rails/myapp/releases/20130919002235 && RAILS_ENV=production RAILS_GROUPS=assets bundle exec rake assets:precompile"

. . .
In trying to debug the problem I've tried completely removing disk_files.js.coffee and then the same error occurs for application.js.
I've then changed my application.js manifest so that it doesn't require anything and then I get a similar error for application.css
I've commented out my custom css and now I get:
** [out :: persephone] rake aborted!
** [out :: persephone] undefined method `[]' for nil:NilClass
** [out :: persephone] (in /rails/myapp/releases/20130919200133/app/assets/stylesheets/application.css)
** [out :: persephone] /rails/myapp/shared/bundle/ruby/2.0.0/gems/sprockets-2.10.0/lib/sprockets/sass_functions.rb:63:in `sprockets_context'
Each of these steps requires a git commit to origin and then a cap deploy.
FWIW- adding #encoding: UTF-8 as per SO#9857443 doesn't help.
Anyone know what's going on? How can I debug this?
