沒有rvm，capistrano無法正常工作

Question

我剛剛將開發機器從rvm更改為rbenv，但是我的生產機器仍在使用rvm。 現在，當我嘗試部署時，出現以下錯誤消息：

cap deploy

    from /home/map7/.rbenv/versions/1.9.2-p290/bin/cap:19:in `<main>'

這是我的deploy.rb

require 'bundler/capistrano'
require 'thinking_sphinx/deploy/capistrano'

set :application, "myapp"
set :repository,  "myuser@localhost:/home/myuser/myapp"

# Deployment options
set :deploy_to, "/home/remoteuser/myapp"
set :deploy_via, :copy

# Remote user info
set :user, "myuser"
set :use_sudo, false
default_run_options[:pty] = true

# Version control system 
set :scm, :git
set :branch, "master"

# Add RVM's lib directory to the load path.
$:.unshift(File.expand_path('./lib', ENV['rvm_path']))

# Load RVM's capistrano plugin.    
require "rvm/capistrano"
set :rvm_ruby_string, '1.9.2'
set :rvm_type, :user  # Don't use system-wide RVM

...

我不想徹底改變服務器，我覺得如果我刪除rvm並在沒有版本控制系統的情況下安裝ruby會更好，但會造成破壞。

有沒有一種方法可以解決此錯誤，而無需更改服務器上的rvm和我的開發設備上的rbenv？ 如果不是，我應該擺脫rvm並在服務器上使用rbenv嗎？

您需要在測試中包裝rvm代碼：

if ENV['rvm_path']
  $:.unshift(File.expand_path('./lib', ENV['rvm_path']))
  require "rvm/capistrano"
  set :rvm_ruby_string, '1.9.2'
  set :rvm_type, :user
end

如果仍然需要RVM在生產環境中進行部署，請執行以下操作：

• 安裝RVM
• 刪除采購線
• 在〜/ .bash_profile中設置export rvm_path=/path/to/rvm

要么：

• 克隆git：//github.com/wayneeseguin/rvm.git
• 在〜/ .bash_profile中設置export rvm_path=/path/to/rvm
