capistrano cap deploy:冷错误

Question

生产服务器: Ubuntu 12.04、Apache、Passenger、RVM、Ruby 2、Rails 4、Postgresql

在cap deploy:cold (我更改了用户名和IP)之后，我得到了这个错误：

我基本上遵循了铁路广播一集“部署到副总裁”的说明。这是我的deploy.rb文件：

require "bundler/capistrano"


server "192.33.333.333", :web, :app, :db, primary: true

set :application, "captest"
set :user, "user"
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false

set :scm, "git"
set :repository, "git@github.com:user/#{application}.git"
set :branch, "master"

default_run_options[:pty] = true
ssh_options[:forward_agent] = true

after "deploy", "deploy:cleanup" # keep only the last 5 releases

namespace :deploy do
  task :start do; end
  task :stop do; end
  task :restart, roles: :app, except: {no_release: true} do
    run "touch #{deploy_to}/current/tmp/restart.txt"
  end

  task :setup_config, roles: :app do
    sudo "ln -nfs #{current_path}/config/apache.conf /etc/apache2/sites-available/#{application}"
    run "mkdir -p #{shared_path}/config"
    put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml"
    puts "Now edit the config files in #{shared_path}."
  end
  after "deploy:setup", "deploy:setup_config"
end

我尝试了直接从服务器上捆绑安装，但不知道在哪里，因为我对应用程序结构感到困惑。我还尝试了'require rvm/capistrano‘，但也得到了错误。

Answer 1

您仍然没有看到真正的错误是什么。

如果cap：-v命令没有告诉您真正的问题，那么ssh进入服务器并运行命令：cd /home/user/apps/captest/releases/20130304111807 && bundle install --gemfile /home/user/apps/captest/releases/20130304111807/Gemfile --path /home/user/apps/captest/shared/bundle --deployment --quiet --without development test

听起来你的ruby环境可能没有在服务器上正确设置。

编辑:实际上，如果它被删除了，它可能不会工作。我遇到了类似的问题，我通过手动将项目克隆到我的生产服务器并运行bundle install来调试任何问题来解决它。

Answer 2

您需要在目标服务器上安装bundler。

gem install bundler

它通常是您需要以这种方式安装的唯一gem，因为它不能自行安装。

这个要点并不完全适合您的需求，但这是我引导Ruby2.0Ubuntu服务器的方法，可能会对您有所帮助：https://gist.github.com/cmaitchison/4083459

Answer 3

我遇到了同样的问题，并决定了一个解决方案。

在您的服务器上，卸载所有版本的Bundler。系统将提示您删除可执行文件。选择yes。然后是gem install bundler，它应该安装1.3.2或更高版本。

在Gemfile中，确保源文件是https，而不是http。source 'https://rubygems.org'
