已安裝Gem，但未找到捆綁顯示

Question

我無法使用我的Rails應用程序獲取pg gem。

當我用sudo的包安裝，我得到：

Using rake (10.0.4) 
Using i18n (0.6.4) 
Using multi_json (1.7.2) 
Using activesupport (3.2.8) 
Using builder (3.0.4) 
Using activemodel (3.2.8) 
Using erubis (2.7.0) 
Using journey (1.0.4) 
Using rack (1.4.5) 
Using rack-cache (1.2) 
Using rack-test (0.6.2) 
Using hike (1.2.1) 
Using tilt (1.3.6) 
Using sprockets (2.1.3)

Using mime-types (1.22) 
Using polyglot (0.3.3) 
Using treetop (1.4.12) 
Using mail (2.4.4) 
Using actionmailer (3.2.8) 
Using arel (3.0.2) 
Using tzinfo (0.3.37) 
Using activerecord (3.2.8)

Using coffee-script-source (1.6.2) 
Using execjs (1.4.0) 
Using coffee-script (2.2.0) 
Using rack-ssl (1.3.3) 
Using json (1.7.7) 
Using rdoc (3.12.2) 
Using thor (0.18.1) 
Using railties (3.2.8) 
Using coffee-rails (3.2.2) 
Using jquery-rails (2.2.1) 
Using pg (0.15.0) 
Using bundler (1.1.5) 
Using rails (3.2.8) 
Using sass (3.2.7) 
Using sass-rails (3.2.6) 
Using uglifier (1.3.0) 

然而，當我對任何寶石做一個「包秀」，我得到：

Could not find pg-0.15.0 in any of the sources 

此外，當我做任何耙指令，我得到：

/usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/spec_set.rb:90:in `block in materialize': Could not find pg-0.15.0 in any of the sources (Bundler::GemNotFound)

     from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:60:in `require'

     from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:35:in `require' 
     from /usr/local/rvm/gems/ruby-1.9.3-p194/bin/ruby_noexec_wrapper:9:in `<main>' 

我懷疑它與RVM和我使用的是哪個版本的Ruby有關我最近改爲1.9.3。有任何想法嗎？

嘗試bundle install沒有sudo。
