Capistrano部署的问题：迁移

尝试部署时出现以下错误：使用Capistrano迁移：

[err :: 127.0.0.1 ] /home/synapse/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems.rb:388:in `bin_path': can't find gem rake ([">= 0"]) with executable rake (Gem::GemNotFoundException) 

在此之前，我得到了rake not found’错误但是在我将“set：rake”添加到deploy.rb之后它就消失了。 Ruby通过RVM安装，当然安装了rake gem。

对于capistrano，您需要为rvm添加扩展名

 set :rvm_ruby, "ruby-1.9.2-p180" set :rvm_gem_home, "#{fetch(:base_dir)}/.rvm/gems/#{fetch(:rvm_ruby)}" set :rvm_ruby_path, "#{fetch(:base_dir)}/.rvm/rubies/#{fetch(:rvm_ruby)}" set :default_environment, { 'RUBY_VERSION' => fetch(:rvm_ruby), 'GEM_HOME' => "#{fetch(:rvm_gem_home)}:#{fetch(:rvm_gem_home)}@global", 'BUNDLE_PATH' => fetch(:rvm_gem_home), 'PATH' => "#{fetch(:rvm_gem_home)}/bin:#{fetch(:rvm_gem_home)}@global/bin:#{fetch(:rvm_ruby_path)}/bin:/home/rails/.rvm/bin:$PATH;", }
