我安裝使用Capistrano的MacPorts的，但capify找不到Capistrano的寶石

Question

使用的MacPorts在OS X 10.7.5我Capistrano的安裝如下：

[~] > install rb-capistrano 

但是當我運行capify，我得到以下錯誤：

/opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem capistrano (>= 0) (Gem::LoadError) 
from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:214:in `activate' 
from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:1082:in `gem' 
from /opt/local/bin/capify-1.8:18 

這顯然是一個與MacPorts部署capistrano，紅寶石和寶石的錯誤，但有沒有辦法解決這個問題？我只想讓Capistrano工作，我根本不在乎Ruby on Rails或Ruby。

Answer 1

以下是我的解決方法：手動安裝gem，或使用rvm進行安裝，完全繞過MacPorts。

我選擇了選項1：使用「gem」來安裝Capistrano。當然，這涉及到安裝MacPorts的寶石和固定安裝到實際工作：

12:10 ~project ➤ which gem 
/usr/bin/gem 
12:10 ~project ➤ sudo port install rb-rubygems 
12:11 ~project ➤ ln -s /opt/local/libexec/ruby1.8/gem /opt/local/bin/gem 
12:11 ~project ➤ sudo gem install capistrano

正如你可以看到，創業板通過安裝到/ opt做「正確的事」對我/本地/（即：使用MacPorts）目錄。

這已被錯誤報道的MacPorts爲https://trac.macports.org/ticket/39467
