Capistrano部署的问题：迁移 [英] Problems with Capistrano's deploy:migrate

问题描述

尝试部署时遇到以下错误：使用Capistrano迁移：

I'm getting the following error while trying to deploy:migrate with Capistrano:

[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)

在获得耙之前未找到错误，但在我将 set：rake添加到deploy.rb后消失了。 Ruby是通过RVM安装的，并且rake gem当然是安装的。

Before that I was getting rake not found' error but it was gone after I added "set :rake" to deploy.rb. Ruby is installed via RVM and rake gem is of course installed.

推荐答案

对于capistrano，您需要添加rvm扩展名

for capistrano you need to add extensions for rvm

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;",
}
