Error ""The directory 'X' does not exist on the server", run 'mina setup' first!

[Josua Muheim]

I need to deploy a new version of a Rails app.

I did not succeed yet, because of this:

Gem::InstallError: mobility requires Ruby version >= 2.3.7.
       Using css_parser 1.7.0
       An error occurred while installing sassc (2.0.1), and Bundler cannot continue.
       Make sure that `gem install sassc -v '2.0.1'` succeeds before bundling.
 !     ERROR: Deploy failed.

I looked at RVM on the server:

$ rvm list

rvm rubies

   ruby-2.2.5 [ x86_64 ]
   ruby-2.3.1 [ x86_64 ]
=* ruby-2.4.1 [ x86_64 ]

Looks all good to me, so I wanted to check the mina log, where I see a lot of "The directory '/home/www-data/XXX/rails/shared/vendor/YYY' does not exist on the server" errors:

$ mina deploy --verbose
-----> Ensuring everyting is pushed to git
       $ if [ $(git log origin/master..master | wc -l) -ne 0 ]; then
         echo "! Your branch master needs to be pushed to origin before deploying"
         exit 1
       fi
       Elapsed time: 0.02 seconds
-----> Creating a temporary build path
       $ touch "deploy.lock"
       $ mkdir -p "$build_path"
       $ cd "$build_path"
-----> Fetching new git commits...
-----> Symlinking shared paths
       $ if [ ! -d  "/home/www-data/XXX/rails/shared/vendor/bundle" ]; then
           echo "! ERROR: not set up."
           echo "The directory '/home/www-data/XXX/rails/shared/vendor/bundle' does not exist on the server"
           echo "You may need to run 'mina setup' first"
           exit 18
         fi
       $ mkdir -p ./vendor
       $ rm -rf "./vendor/bundle"
       $ ln -s "/home/www-data/XXX/rails/shared/vendor/bundle" "./vendor/bundle"
       $ if [ ! -d  "/home/www-data/XXX/rails/shared/log" ]; then
           echo "! ERROR: not set up."
           echo "The directory '/home/www-data/XXX/rails/shared/log' does not exist on the server"
           echo "You may need to run 'mina setup' first"
           exit 18
         fi
       $ mkdir -p .
       $ rm -rf "./log"
       $ ln -s "/home/www-data/XXX/rails/shared/log" "./log"
       $ if [ ! -d  "/home/www-data/XXX/rails/shared/tmp/cache" ]; then
           echo "! ERROR: not set up."
           echo "The directory '/home/www-data/XXX/rails/shared/tmp/cache' does not exist on the server"
           echo "You may need to run 'mina setup' first"
           exit 18
         fi

I have no idea why these errors are displayed, because the respective folders actually do exist on the server:

$ /home/www-data/XXX/rails/shared/log
-bash: /home/www-data/XXX/rails/shared/log: Is a directory

Also running $ mina setup again doesn't solve this.

I also have no idea why Mina is not taking the default Ruby (2.4.1) when installing gems?

Can anyone please give some support here? Thank you.

@jmuheim please post your deploy.rb

[Ajmal Eylia]

in deploy.rb

task :remote_environment do
  # If you're using rbenv, use this to load the rbenv environment.
  # Be sure to commit your .ruby-version or .rbenv-version to your repository.
  # invoke :'rbenv:load'

  # For those using RVM, use this to load an RVM version@gemset.
  # invoke :'rvm:use', 'ruby-1.9.3-p125@default'
  
  invoke :'rvm:use', 'ruby-2.4.1@default'
end

I debugged a lot of stuff, and it seems to me that there's a problem somewhere deeper.

I tried with both rbenv and RVM, and it didn't work. Both of them produce this error:

       Installing mobility 0.8.7
       
       Gem::InstallError: mobility requires Ruby version >= 2.3.7.
       Using css_parser 1.7.0
       An error occurred while installing sassc (2.0.1), and Bundler cannot continue.
       Make sure that `gem install sassc -v '2.0.1'` succeeds before bundling.
 !     ERROR: Deploy failed.

What makes me really suspicious is that RVM seems to be loaded correctly with Ruby 2.4.1:

-----> Using RVM environment "ruby-2.4.1@staging-audit"
       ruby-2.4.1 - #gemset created /home/www-data/.rvm/gems/ruby-2.4.1@staging-audit
       ruby-2.4.1 - #generating staging-audit wrappers..........
       Using /home/www-data/.rvm/gems/ruby-2.4.1 with gemset staging-audit

So why is bundler complaining about mobility requires Ruby version >= 2.3.7?

Here's the current version of my script:

require 'mina/rails'
require 'mina/git'
require 'mina/puma'
require 'mina/rvm'    # for rvm support. (https://rvm.io)

set :application_name, 'A4AA 2.0'
set :domain, 'zugangfueralle01.nine.ch'
set :deploy_to, '/home/www-data/staging-audit.access4all.ch/rails'
set :repository, '[e-mail]:Access4all/a4aa2.git'
set :branch, 'master-nine'

set :user, 'www-data'          # Username in the server to SSH to.
set :forward_agent, true   # SSH forward_agent.

set :shared_dirs, fetch(:shared_dirs, []).push('log', 'tmp', 'public/uploads', 'shared/tmp/sockets', 'shared/tmp/pids')
set :shared_files, fetch(:shared_files, []).push('config/secrets.yml')

task :remote_environment do
  invoke :'rvm:use', 'ruby-2.4.1@staging-audit'
end

task :setup do
end

desc "Deploys the current version to the server."
task :deploy do
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    on :launch do
      invoke :'puma:phased_restart'
    end
  end
end

I have both .ruby-version and .ruby-gemset pushed to the repo. When I tried setting a non-sense value like asdf to .ruby-version, neither rbenv nor RVM complained. As far as I understand, at least rbenv should take its version information from these files...?

Thanks for any help.

task :setup do
  command %{rvm install ruby-2.4.1}
  command %{gem install bundler}
end

try update your :setup and run mina setup

Hey @jmuheim

Did you look at the faq ?

The part with mina running in a non-interactive ssh mode, so you should add all your export/source lines (including the .rbenv path variable) to the top of your .bashrc file.

[Josua Muheim]

Hey guys

Thanks for helping me. I successfully deployed up to the step where Mina would start Puma server. I'm using https://github.com/untitledkingdom/mina-puma for this, I will ask for help there.

All the best.
