ruby-on-rails - bundle : Permission denied

我将服务器更新为ruby 2.1.1，并且正在使用Capistrano部署到服务器。但是，当我部署时，会收到各种错误。每次更改部署代码时都会发生变化。以下是我当前遇到的问题。

更新/新问题

重新安装rvm和ruby之后，我现在在部署时遇到了不同的问题。这是我当前的deploy.rb文件。

require "bundler/capistrano"
require "rvm/capistrano"

set :rvm_type, :system
set :rvm_ruby_string, "ruby-2.1.1"

require 'bundler/capistrano'

# Capistrano
set :default_environment, {
    'PATH' => '/root/.rvm/gems/ruby-2.1.1/bin:/root/.rvm/gems/ruby-2.1.1@global/bin:/usr/local/rvm/rubies/ruby-2.1.1/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games',
    'GEM_HOME' => "/root/.rvm/gems/ruby-2.1.1",
    'GEM_PATH' => "/root/.rvm/gems/ruby-2.1.1:/root/.rvm/gems/ruby-2.1.1@global",
    "MY_RUBY_HOME" => "/usr/local/rvm/rubies/ruby-2.1.1",
    "BUNDLE_PATH" => "/usr/local/rvm/rubies/ruby-2.1.1/bin/bundle"

}

set :rails_env, "production"
set :branch,    "master"

set :app_server, "ip"
set :db_server,  "ip"
server app_server, :app, :web
role :db, db_server, :primary => true

set :keep_releases, 1

set :deploy_to, "/var/www"
set :user, :jason
set :password, "cool password here"

set :repository, "git url"  # Your clone URL
set :scm, "git"
set :scm_username, "jason"
set :scm_passphrase, "password"

set :use_sudo, false

default_run_options[:pty] = true

set :ssh_options, {:forward_agent => true}

after 'deploy:restart', 'deploy:cleanup'
after 'deploy:update', 'deploy:create_symlink'

运行部署时，我会遇到此错误:

Error: RVM was unable to use 'default'

我假设这是指我未设置的rvm_ruby_string。除此之外，我不知道为什么会产生错误。也许RVM无法识别服务器上的ruby？

旧问题

我将服务器更新为ruby 2.1.1。通过SSH进入服务器，我运行gem env抢夺了default environment的相对特征。

set :default_environment, {
    'PATH' => '/root/.rvm/gems/ruby-2.1.1/bin:/root/.rvm/gems/ruby-2.1.1@global/bin:/usr/local/rvm/rubies/ruby-2.1.1/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games',
    'GEM_HOME' => "/root/.rvm/gems/ruby-2.1.1",
    'RUBY_VERSION' => 'ruby 2.1.1',
    'GEM_PATH' => "/root/.rvm/gems/ruby-2.1.1:/root/.rvm/gems/ruby-2.1.1@global"
}

但是，当我运行cap deploy时，我得到了:

  * executing "cd /var/www/releases/20140517014048 && bundle install --gemfile /var/www/releases/20140517014048/Gemfile --path /var/www/shared/bundle --deployment --quiet --without development test"
    servers: ["ip address"]
    ["ip address"] executing command
 ** [out :: ipaddress] sh: 1: bundle: Permission denied

我认为这是我的默认环境。因为那是我在deploy.rb文件中更改的唯一内容。 `

最佳答案

Capistrano

第一步是确保default_environment正常工作。尽管找不到direct reference (search for default_env on this page)，但我读到default_environment已被default_env取代

如果您使用的是capistrano 3.0+，则应这样使用default_env:

set :default_env, {
    'PATH' => '/root/.rvm/gems/ruby-2.1.1/bin:/root/.rvm/gems/ruby-2.1.1@global/bin:/usr/local/rvm/rubies/ruby-2.1.1/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games',
    'GEM_HOME' => "/root/.rvm/gems/ruby-2.1.1",
    'RUBY_VERSION' => 'ruby 2.1.1',
    'GEM_PATH' => "/root/.rvm/gems/ruby-2.1.1:/root/.rvm/gems/ruby-2.1.1@global"
}

权限

其次，您的ssh用户将没有正确的权限来访问Ruby/bundler的安装

正如您在评论中所讨论的，这可能是由于系统上未安装ruby或rvm或没有访问权限所致。
@chloe有一个很棒的建议-为此，我将使用root用户登录(以进行测试)，以确保您实际上可以正确访问bundler或rvm数据
