Question

刚刚通过rbenv将新版本的ruby安装到我的服务器上。

rbenv versions返回：

system
2.2.3
* 2.3.3 (set by /opt/pesto/current/config/.ruby-version)

我正在尝试重启我的独角兽服务（sudo service unicorn restart）：

Couldn't restart.

绝望中，我尝试开始（sudo service unicorn start）：

Could not find erubis-2.7.0 in any of the sources
Run `bundle install` to install missing gems.

我已经运行了bundle install。当我rbenv local 2.3.3以及rbenv global 2.3.3，然后gem list时，我看到了：

 'erubis (2.7.0)'

显而易见。也就是说 - 这个宝石绝对存在。

所以我看到它是否与我的其他版本做了一些奇怪的事情。我改为rbenv global 2.2.3和rbenv local 2.2.3并做了：

gem install erubis -v 2.7.0

在这之后，现在错误是抱怨另一个不同的宝石，它已经可以在我的2.3.3宝石列表中找到...所以我得出的结论是它肯定只看2.2.3宝石列表，因为添加gem到2.2.3修复了问题。

简单地运行bundle install for 2.2.3不是一个选项 - 我需要仅在我的2.3.3发行版中可用的依赖项。我真正想要的是，独角兽只能参考2.3.3中提供的内容，并放弃查看2.2.3以及那里有哪些宝石。

这是我的unicorn.rb：

app_path = File.expand_path(File.dirname(__FILE__) + '/..')
# Set the working application directory
# working_directory "/path/to/your/app"
working_directory app_path

before_exec do |server|
  ENV['BUNDLE_GEMFILE'] = "#{root}/Gemfile"
end


# Set the location of the unicorn pid file. This should match what we 
 put in the
# unicorn init script later.
pid (ENV['UNICORN_PID_PATH'] || "#{app_path}/tmp/") + 'unicorn.pid'

# You should define your stderr and stdout here. If you don't, stderr 
defaults
# to /dev/null and you'll lose any error logging when in daemon mode.
stderr_path(app_path + '/log/unicorn.log') unless ENV['RAILS_ENV'] == 
'development'
stdout_path(app_path + '/log/unicorn.log') unless ENV['RAILS_ENV'] == 
'development'

# Unicorn socket
listen('127.0.0.1:3000', backlog: 64, :tcp_nopush => true) if 
ENV['RAILS_ENV'] == 'development'
list en(app_path + '/tmp/unicorn.sock', backlog: 64) unless 
ENV['RAILS_ENV'] == 'development'
listen(8080, :tcp_nopush => true) unless ENV['RAILS_ENV'] == 
'development'

# Number of processes
# worker_processes 4
worker_processes (ENV['RAILS_ENV'] == 'production' ? 16 : 1)

# Time-out
timeout 300

# Load the app up before forking.
preload_app true

# Garbage collection settings.
 GC.respond_to?(:copy_on_write_friendly=) &&
  GC.copy_on_write_friendly = true

# If using ActiveRecord, disconnect (from the database) before 
forking.
before_fork do |server, worker|
   defined?(ActiveRecord::Base) &&
     ActiveRecord::Base.connection.disconnect!
end

# After forking, restore your ActiveRecord connection.
after_fork do |server, worker|
  defined?(ActiveRecord::Base) &&
    ActiveRecord::Base.establish_connection
end

我不知道在这个配置文件中引用了它所引用的ruby版本。因此，我想弄清楚如何让独角兽使用我的新红宝石。

Answer 1

独角兽使用的rails版本可以在/etc/init.d/unicorn中编辑。我改变了它并且有效。

Unicorn不使用rbenv版本或rails -v版本
