ruby-on-rails – 无法使用Capistrano和RVM部署Rails应用程序

发布时间：2020-12-17 04:15:06 所属栏目：百科来源：网络整理

导读：我有一个我用Capistrano部署的Rails应用程序.我在服务器上安装了RVM,因为我想使用更新版本的 Ruby并将其添加到我的deploy.rb文件中(根据我发现的各种说明)： $:.unshift(File.expand_path('./lib',ENV['rvm_path']))require 'rvm/capistrano'set :rvm_ruby_s

我有一个我用Capistrano部署的Rails应用程序.我在服务器上安装了RVM,因为我想使用更新版本的 Ruby并将其添加到我的deploy.rb文件中(根据我发现的各种说明)：

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

当我运行cap cap时,会发生这种情况：

[staging.example.com] executing command
 ** [out :: staging.example.com] /usr/local/lib/site_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem bundler (>= 0) (

为什么capistrano使用Ruby 1.8？我的道路显然也搞砸了.

这是staging.example.com上rvm info的输出：

ruby-1.9.2-p180:

system:
  uname:       "Linux staging 2.6.39.1-linode34 #1 SMP Tue Jun 21 10:29:24 EDT 2011 i686 GNU/Linux"

  zsh:         " => not installed"

rvm:

  RUBYOPT:      ""
  gemset:       ""

解决方法

实际上rvm-capistrano文档页面上的最新文档声明它必须是这样的：

# RVM bootstrap: change to your Ruby and GemSet
require 'rvm/capistrano'
set :rvm_ruby_string,ENV['GEM_HOME'].gsub(/.*//,"")
set :rvm_type,:user
