ruby-on-rails - Capistrano:无法访问 `~/releases/':没有这样的文件或目录

Question

在我的本地计算机和服务器上执行bundle update 后，我无法再进行部署。正如我猜的那样，我得到的错误是某种权限，但我无法了解正在发生的事情:

我的 deploy.rb 看起来像这样:

# The name of the app
set :application, "strana_cvetov"

# The address of the remote host
set :location, "robotinthecloak.com"

# setup some Capistrano roles
role :app, location
role :web, location
role :db,  location, :primary => true

# The directory on the server that will be deployed to
set :deploy_to, "~/rails_apps/#{application}"
# The type of Source Code Management system
set :scm, :git
# The location of the LOCAL repository relative to the current app
set :repository,  "ssh://ubuntu@#{location}/~/git/#{application}.git"
# The way in which files will be transferred from repository to remote host
set :deploy_via, :copy

set :use_sudo,            false
#tell git to clone only the latest revision and not the whole repository
set :git_shallow_clone,   1
set :keep_releases,       5

#options necessary to make Ubuntu’s SSH happy
ssh_options[:paranoid]    = false
default_run_options[:pty] = true

set :rails_env, :production

# Set up SSH so it can connect to the EC2 node - assumes your SSH key is in ~/.ssh/id_rsa
set :user, "ubuntu"

# Passenger
namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  namespace :assets do
    task :precompile, :roles => :web, :except => { :no_release => true } do
      run "cd #{current_path} && #{bundle exec rake} RAILS_ENV=#{rails_env} RAILS_GROUPS=assets assets:precompile --trace"
    end
  end
end

after "deploy:create_symlink", "deploy:resymlink", "deploy:update_crontab"

当我运行 deploy:check 时，它说 You appear to have all necessary dependencies installed。

我搜索了网络、这个站点，尝试了所有我能找到的解决方案，但没有任何效果。

该服务器上的其他项目也没有部署同样的错误，但几天前一切正常，我在那里什么也没碰。怎么回事？

Answer 1

使用部署到的完整路径，'~'可能是骗人的

set :deploy_to, "/home/username/rails_apps/#{application}"
