capistrano 无法运行 ssh：没有这样的文件或目录

Question

我是 capistrano 的新手，我正在尝试建立一个测试项目，但正如您所猜想的那样，没有太大的成功。当我运行cap deploy:update 时，我得到以下输出：

$ cap deploy
  * 2014-12-27 21:48:06 executing `deploy'
  * 2014-12-27 21:48:06 executing `deploy:update'

这是 deploy.rb 文件：

begin
    require 'colored'
rescue LoadError
    $stderr.puts <<-INSTALL
You need the both the capistrano-ext and colored gems to deploy this application
Install the gems like this:
    gem install colored
    INSTALL
    exit 1
end

set :application, "stocksolutions"
set :repository,  "git@github.com:hstandaert/test.git"
set :branch, "production"

set :user, 'stocksolutions.be'
set :deploy_to, "/customers/4/b/b/#{user}/httpd.www/private"
set :use_sudo, false

set :scm, :git

default_run_options[:pty] = true

server "ssh.stocksolutions.be", :app, :web

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
end

谁能发现我的错误？

Answer 1

您的日志似乎表明您的部署服务器中没有安装 ssh 客户端，或者在服务器的 PATH 中找不到该命令。

通过更改以下内容尝试通过 https 而不是 ssh 克隆 repo 是否可行：

之前

set :repository,  "git@github.com:hstandaert/test.git"

之后

set :repository,  "https://github.com/hstandaert/test.git"

系统会要求您提供登录凭据，以便 github 能够克隆 repo。
