這個錯誤是什麼意思？

只是在這裏尋找一個超級簡單的答案。這個錯誤是什麼意思？

我的應用程序將返回此：

Error message: 
    git://github.com/spree/spree.git (at master) is not checked out. Please run `bundle install` (Bundler::GitError) 
Exception class: 
    PhusionPassenger::UnknownError 
Application root: 
    /home/shadyfront/webapps/revolting_age/Age-of-Revolt

這是什麼意思，「未簽出」？

我這裏有我的nginx.conf：

env GEM_HOME=/home/shadyfront/.rvm/gems/[email protected]_gems;

當我執行bundle show spree：

#> /home/shadyfront/.rvm/gems/[email protected]/bundler/gems/spree-1706124f2f94

而且我這裏有我的寶石ENV：

RubyGems Environment:

    - RUBY VERSION: 1.8.7 (2010-12-23 patchlevel 330) [i686-linux]

捆綁安裝每次都會通過。
