獨角獸和Gemfile在試圖在數字海洋上運行獨角獸和Nginx時使用的是不同的ruby版本

Question

我想通過Nginx和Unicorn運行我的Rails應用程序，當我嘗試運行service unicorn start時，它告訴我我以失敗master failed to start, check stderr log for details。我的Gemfile指定了ruby 2.0.0，我的ruby版本是2.0.0p353。獨角獸似乎在使用紅寶石2.1.3。有沒有什麼辦法讓獨角獸使用ruby 2.0.0，如果它使用2.1.3默認的話。

當我尾巴麒麟日誌：

/usr/local/rvm/gems/ruby-2.1.3/gems/unicorn-4.8.3/lib/unicorn/http_server.rb:294:in `join' 
/usr/local/rvm/gems/ruby-2.1.3/gems/unicorn-4.8.3/bin/unicorn:126:in `<top (required)>'

它看起來像錯誤可能從麒麟被位於/usr/local/rvm/gems/ruby-2.1.3/bin/和我的其他的寶石在/usr/local/rvm/gems/ruby-2.0.0-p353/bin/被制止。

我unicorn.conf樣子：

worker_processes 4 
user "rails" 
working_directory "/home/rails" 
pid "/home/unicorn/pids/unicorn.pid" 
stderr_path "/home/unicorn/log/unicorn.log" 
stdout_path "/home/unicorn/log/unicorn.log" 

我的獨角獸文件/etc/init.d樣子：

set -e 
NAME=unicorn 
DESC="Unicorn web server" 

. /lib/lsb/init-functions 

if [ -f /etc/default/unicorn ]; then 
    . /etc/default/unicorn 
fi 

PID=${PID-/run/unicorn.pid} 

run_by_init() { 
    ([ "${previous-}" ] && [ "${runlevel-}" ]) || [ "${runlevel-}" = S ] 
} 

exit_with_message() { 
    if ! run_by_init; then 
    log_action_msg "$1 Not starting." 
    fi 
    exit 0 
} 

check_config() { 
    if [ $CONFIGURED != "yes" ]; then 
    exit_with_message "Unicorn is not configured (see /etc/default/unicorn)." 
    fi 
} 

check_app_root() { 
    if ! [ -d $APP_ROOT ]; then 
    exit_with_message "Application directory $APP_ROOT is not exist." 
    fi 
} 

set -u 
``` 
And the start function in that file: 
``` 
    start) 
     check_config 
     check_app_root 

     log_daemon_msg "Starting $DESC" $NAME || true 
     if start-stop-daemon --start --quiet --oknodo --pidfile $PID --exec $DAEMON -- $UNICORN_OPTS; then 
      log_end_msg 0 || true 
     else 
      log_end_msg 1 || true 
     fi 
       ;; 

其次是像重新啓動其他命令，停止等。

而且我的Gemfile：

source 'https://rubygems.org' 
ruby '2.0.0' 
gem 'rails', '4.0.0' 
gem 'sass-rails', '4.0.1' 
gem 'uglifier', '2.4.0' 
gem 'coffee-rails', '4.0.1' 
gem 'jquery-rails' 
gem 'jbuilder', '1.5.3' 
gem 'bootstrap-sass', '3.1.1.0' 
gem 'figaro' 
gem 'rolify' 
gem 'simple_form' 
gem 'bcrypt-ruby', :require => 'bcrypt' 
gem 'rails_12factor' 
gem 'pg' 
gem 'notes-cli' 
gem 'twitter-typeahead-rails' 
gem 'gon' 

group :development do 
    gem 'better_errors' 
    gem 'binding_of_caller', :platforms=>[:mri_19, :mri_20, :rbx] 
    gem 'quiet_assets' 
    gem 'rails_layout' 
    gem 'mailcatcher' 
    gem 'rails-erd' 
    gem 'annotate' 
end 

group :development, :test do 
    gem 'factory_girl_rails' 
    gem 'rspec-rails' 
    gem 'faker' 
    gem 'pry' 
    gem 'rb-fsevent' 
    gem 'guard-rspec' 
    gem 'terminal-notifier-guard' 
end 

group :test do 
    gem 'capybara', '2.4.3' 
    gem 'database_cleaner' 
    gem 'email_spec' 
end 

我會很感激的任何幫助。我是Digital Ocean，Unicorn和Nginx的新手，我的唯一經歷 在「部署」中使用Heroku。
