在Capistrano部署之后，Rails资产没有编译

我正在使用Capistrano部署我的Rails应用程序，似乎资产没有被编译，除非我进入服务器并运行RAILS_ENV=development bundle exec rake assets:precompile手动RAILS_ENV=development bundle exec rake assets:precompile 。

我已经尝试按照capistrano / rails github页面上的说明进行操作，但我不确定我是否错过了某些内容。

运行cap production deploy成功完成。 但我不知道如何检查assets:precompile任务是否实际运行。 运行cap production deploy:assets:precompile也成功完成，但服务器上没有明显变化。

版本

 Server version: Apache/2.4.7 (Ubuntu) Phusion Passenger 5.0.22 ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux] Rails 4.2.5 capistrano (3.1.0) capistrano-bundler (1.1.4) capistrano-rails (1.1.6) capistrano-rbenv (2.0.4) 

Capfile

 require 'capistrano/setup' require 'capistrano/deploy' require 'capistrano/rbenv' require 'capistrano/rails/assets' Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r } 

配置/ deploy.rb

 set :application, "website" set :repo_url, "[e-mail]:company/website.git" set :deploy_to, "/var/www/#{fetch(:application)}" set :user, "webmaster" set :rbenv_path, '/home/webmaster/.rbenv' set :rbenv_ruby, '2.2.3' set :assets_roles, [:web, :app] set :keep_assets, 2 set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/uploads') set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml') 

配置/部署/ production.rb

 set :stage, :production server 'company.com', user: 'webmaster', roles: %{web app db} 

任何有关资产未编译的想法？

[工作方案]

的Gemfile

 group :development do gem 'capistrano', '~> 3.1.0' gem 'capistrano-bundler', '~> 1.1.2' gem 'capistrano-rails', '~> 1.1.1' gem 'capistrano-rbenv', '~> 2.0.4' end 

Capfile

 require 'capistrano/setup' require 'capistrano/deploy' require 'capistrano/rbenv' require 'capistrano/rails' # Same as requiring capistrano/bundler, capistrano/rails/assets and capistrano/rails/migrations Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r } 

配置/ deploy.rb

 set :application, "website" set :repo_url, "[e-mail]:company/website.git" set :deploy_to, "/var/www2/#{fetch(:application)}" set :user, "webmaster" set :rbenv_path, '/home/webmaster/.rbenv' set :rbenv_ruby, '2.2.3' set :assets_roles, [:web, :app] set :keep_assets, 2 set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/uploads') set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml') namespace :deploy do desc "Restart application" task :restart do on roles(:app), in: :sequence, wait: 5 do execute :touch, release_path.join("tmp/restart.txt") end end after "deploy:publishing", "deploy:restart" end 

配置/部署/ production.rb

确保使用％w {}

 set :stage, :production server 'company.com', user: 'webmaster', roles: %w{web app db} 

部署输出

如果成功，您应该在输出中看到与此类似的内容：

 INFO [2412d16d] Running /home/webmaster/.rbenv/bin/rbenv exec bundle exec rake assets:precompile as [e-mail] DEBUG [2412d16d] Command: cd /var/www/website/releases/20160302030846 && ( export RBENV_ROOT="/home/webmaster/.rbenv" RBENV_VERSION="2.2.3" RAILS_ENV="production" ; /home/webmaster/.rbenv/bin/rbenv exec bundle exec rake assets:precompile ) 

Answer 1

由于非常微妙的拼写错误，您没有正确地为您的服务器分配角色：

 server 'company.com', user: 'webmaster', roles: %{web app db} 

它应该是：

 server 'company.com', user: 'webmaster', roles: %w{web app db} 

在Ruby中， %{}与双引号字符串相同，而%w{}是字符串数组。 您需要后者，以便您的服务器具有三个角色， web ， app和db ，而不是一个名为web app db角色。
