Capistranoのエラー - 無効なオプション：known_hosts

Question

私は自分のサーバーを持っている私が働いているサブプロジェクトの作業中に私の同僚のための概念の証明としてカプリストラをセットアップしようとしています。

私はすべての設定を完了しており、初めてデプロイを実行する必要があります.SSH転送はすべて動作していますが、以前は見たことがないエラーが表示されます解決方法への参照：

だから私はカピストラーノは、オプションとしてknown_hostsファイルで何かを実行しようとしていると思うが、に対してそれを実行しようとしているものがオプションを認識しないので、展開が、その前に死にますサーバーに接続しようとしても、cap slimqa01 deployのenterを押すと直ちにエラーが発生します。

誰でも同様の問題がありましたか？以下

deploy.rb：

# config valid only for current version of Capistrano 
lock '3.5.0' 

set :application, 'dashboard-capistrano' 
set :repo_url, 'git@github.com:private/repo.git' 

# Default branch is :master 
ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp 

# Default deploy_to directory is /var/www/my_app_name 
set :deploy_to, '/var/www/dashboard-capistrano' 

# Default value for :scm is :git 
set :scm, :git 

# Default value for :format is :airbrussh. 
set :format, :airbrussh 

# You can configure the Airbrussh format using :format_options. 
# These are the defaults. 
set :format_options, command_output: true, log_file: 'log/capistrano.log', color: :auto, truncate: :auto 

# Default value for :pty is false 
# set :pty, true 

# Default value for :linked_files is [] 
# set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml') 

# Default value for linked_dirs is [] 
# set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'public/system') 

# Default value for default_env is {} 
# set :default_env, { path: "/opt/ruby/bin:$PATH" } 

# Default value for keep_releases is 5 
set :keep_releases, 5 

set :ssh_options, { 
    verbose: :debug 
} 

task :whoami do 
    on roles(:web) do 
     execute :whoami 
    end 
end 

namespace :deploy do 

    after :restart, :clear_cache do 
     on roles(:web), in: :groups, limit: 3, wait: 10 do 
      # Here we can do anything such as: 
      # within release_path do 
      # execute :rake, 'cache:clear' 
      # end 
     end 
    end 

end 

また、私はあまりにも個々のタスクを実行する上でのエラーが表示されます。

andrefigueira@Ubuntu ~/Code/dashboard $ cap slimqa01 whoami 
00:00 whoami 
     01 whoami 
(Backtrace restricted to imported tasks) 
cap aborted! 
ArgumentError: invalid option(s): known_hosts 

Tasks: TOP => whoami 
(See full trace by running task with --trace) 

Answer 1

私は同じ問題がありました。
3.0.2から3.1.1へのnet-sshのアップデート後、動作しています。

gem update net-ssh
