捆綁軟件安裝/耙資產期間，RVM拋出gems目錄權限錯誤：預編譯

Question

在EC2 ubuntu t1.micro實例上，使用RVM管理紅寶石。 將黃瓜添加到Gemfile中並運行bundler進行安裝時，它會安裝一些依賴的寶石，例如小黃瓜。

隨后，當運行rails asset：precompile時，rvm會引發以下權限錯誤。 從這里出發的任何指示都將有所幫助

 $ rake assets:precompile RAILS_ENV=production --trace
/home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/fileutils.rb:245:in `mkdir': Permission denied - /home/ubuntu/.rvm/gems/ruby-2.0.0-p353/extensions/x86_64-linux/2.0.0/gherkin-2.12.2 (Errno::EACCES)
    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/fileutils.rb:245:in `fu_mkdir'
    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/fileutils.rb:219:in `block (2 levels) in mkdir_p'
    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/fileutils.rb:217:in `reverse_each'
    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/fileutils.rb:217:in `block in mkdir_p'

    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/fileutils.rb:203:in `mkdir_p'
    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/site_ruby/2.0.0/rubygems/ext/builder.rb:210:in `write_gem_make_out'
    from /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/site_ruby/2.0.0/rubygems/ext/builder.rb:132:in `build_error'

在隨后的故障排除過程中（通過刪除gem並以本地方式安裝它）也會引發權限錯誤。

$ gem install gherkin
Fetching: gherkin-2.12.2.gem (100%)
ERROR:  While executing gem ... (Errno::EACCES)
Permission denied - /home/ubuntu/.rvm/gems/ruby-2.0.0-p353/gems/gherkin-2.12.2/.gitattributes

通過以sudo用戶身份運行blunder可以解決此問題

$rvmsudo bundle install

仍然不確定為什么非超級用戶會遇到權限問題。
