执行我试图部署具有Capistrano的3代码从Git仓库Ubuntu的服务器，但我发现了这个错误。

============================================== ============================
这是我的Gemfile。

gem 'capistrano', '~> 3.1.0' 

#//Use unicorn as the app server 
gem 'unicorn' 

#// Use Capistrano for deployment 
group :development do 
gem 'capistrano-rails' 
gem 'capistrano-bundler' 
gem 'capistrano-rbenv', "~> 2.0" 
end 

source 'https://rubygems.org' 

=========================================== =============================== ＃deploy.rb

lock '3.1.0' 

#// Define the name of the application 
set :application, 'my_app' 

#// Define where can Capistrano access the source repository 
#// set :repo_url, 'https://github.com/[user name]/[application name].git' 
set :scm, :git 
set :repo_url, 'git@github.com:jaipratik/rw.git' 

set :use_sudo, true 

set :log_level, :debug 

#// Define where to put your application code 
set :deploy_to, "/var/www/my_app" 

set :pty, true 

set :format, :pretty

role :app, %w{ubuntu@{IP/Host}} 

server '{IP/Host}', user: 'ubuntu', roles: %w{web app} 

set :ssh_options, {

Answer 1

Capistrano的WASN无法在ec2上创建文件夹。一旦我创建了它的文件夹就像一个魅力。

所以，如果你也有类似的问题，尝试创建在EC2上的文件夹，然后执行帽生产部署。

Answer 2

那么，在远程机器/var/www/my_app的权限？确保他们是由你在这个配置选项指定的同一用户拥有：

set :user, "mydeployuser" 

如果不相信你正在使用运行在客户机上的“帽子”命令Capistrano的默认用户。请确保它有权修改/创建/var/www/my_app

既然你：

set :use_sudo, true 

它可能是须藤可能没有设置为无密码须藤像建议在第3章docs
