ruby-on-rails - Capistrano 在尝试部署时提示

Question

$ bundle exec cap -S branch=master production deploy --dry-run
/Users/myname/.rvm/lib/rvm/capistrano.rb:5: RVM - Capistrano integration was extracted to a separate gem, install: `gem install rvm-capistrano` and remove the `$LOAD_PATH.unshift` line, note also the 'set :rvm_type, :user' is now the default (instead of :system). (RuntimeError)

这就是我得到的。不知道发生了什么。想法？

编辑 我的 deploy.rb

# RVM is used for ruby 1.9.2 - this is so cap can see the rvm gemset.
$LOAD_PATH.unshift "lib", File.expand_path('./lib', ENV['rvm_path'])

set :stages, %w(sandbox qa production)
require 'capistrano/ext/multistage'
require 'bundler/capistrano'
require 'airbrake/capistrano'
require 'chef/capistrano'
require 'secure_files/capistrano'
require "rvm/capistrano"

set :rvm_ruby_string, '1.9.2'
set :rvm_bin_path, '/usr/local/rvm/bin'
set :user, "root"
set :scm, :git
set :repository,  "git@github.com:Myact/fbadapter.git"
set :deploy_to, '/var/www/fbadapter'
set :deploy_via, :remote_cache
set :rails_env, Proc.new {stage}
set :application, 'fbadapter'
set :default_environment, Proc.new { { 'RAILS_ENV' => stage } }
set :rake, "bundle exec rake --trace"
set :foreman_bin, 'bundle exec foreman'
set :rake, "#{foreman_bin} run rake"  
set :rails, "#{foreman_bin} run rails"
set :app_user, 'www-data'

set :bundle_without,  [:development, :test, :ops, :darwin]

# this must be set before foreman/capistrano is read
set :foreman_roles, [:app]
require "foreman/capistrano"

after 'multistage:ensure' do
 role_from_chef :db, 'app', :limit => 1, :primary => true # perform db operations on one of the app servers
 role_from_chef :web, 'app'
 role_from_chef :app
 role_from_chef :queue
 role_from_chef :cron
end


before 'deploy:symlink', 'deploy:assets:precompile', 'deploy:migrate'
after 'deploy:symlink', :set_application_permissions

after 'deploy', 'deploy:cleanup', 'campfire:deploy_stop'
after 'rollback', 'campfire:deploy_rollback'

desc 'Changes the permissions for the release path to be used with www-data'
task :set_application_permissions do
  run "chown -R #{app_user}:#{app_user} #{release_path}/*"
end

# These services are monitored by monit, but interacting with them that way
# is hugging-every-cat crazy. This means we're assuming two thin procs per
# app server; if that changes then remember to change this too.

namespace :deploy do
  task :stdout_logger do 
    run "cd #{release_path} && #{rails} plugin install https://github.com/ddollar/rails_log_stdout.git"
  end

  before 'deploy:symlink', 'deploy:stdout_logger'
end

这是我的。这些是我必须使用 rvm-capistrano gem 的唯一行。如果有帮助，我也以非 sudo 用户的身份进行部署。

set :rvm_ruby_string, '<interpreter>@<gemset>'

# Load RVM's capistrano plugin.
require "rvm/capistrano"
set :rvm_path, "$HOME/.rvm"

由于您正在运行 bundle exec，请确保 rvm 和 rvm-capistrano gems 在您的 Gemfile 中。还要根据您的需要更改下面的 rvm_ruby_string。

我很确定你也需要删除这一行

LOAD_PATH.unshift "lib", File.expand_path('./lib', ENV['rvm_path'])

我还注意到您正在使用“root”用户进行部署。可以肯定的是，除非为 root 用户安装了 rvm，否则这不会起作用。如果您必须使用 root 用户，我会尽可能使用 rvm 包装器。
