php - Capistrano 错误 - 无效选项 : known_hosts

Question

我正在尝试将 Capistrano 设置为我的同事在我正在处理的子项目上工作的概念证明，该子项目有自己的服务器。

我已经完成了所有的配置，只需要第一次运行部署，SSH 转发就可以了，等等......但是我遇到了一个我以前没有见过的错误，也找不到任何引用如何解决:

    andrefigueira@Ubuntu ~/Code/dashboard $ cap slimqa01 deploy --trace

所以我认为 Capistrano 正在尝试运行带有 known_hosts 作为选项的东西，但它试图运行它的东西不识别该选项，因此部署在它甚至试图联系服务器之前就死了，失败几乎发生了当我在 cap slimqa01 deploy 上按下 enter 键后立即。

有人遇到过类似的问题吗？

deploy.rb 下面:

# 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

我在运行单个任务时也遇到了错误:

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)

我有同样的问题。
将 net-ssh 从 3.0.2 更新到 3.1.1 后，它可以正常工作。

gem 更新 net-ssh
