Gem 已安装，但 bundle show 找不到

Question

我无法让 pg gem 与我的 rails 应用程序一起使用。

当我执行 sudo bundle install 时，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 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)

但是，当我为任何宝石做“捆绑秀”时，我得到：

Could not find pg-0.15.0 in any of the sources

另外，当我执行任何 rake 命令时，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:60:in `rescue in require'

        from /usr/local/rvm/gems/ruby-1.9.3-p194/bin/ruby_noexec_wrapper:9:in `<main>'

我怀疑这与 RVM 以及自从我最近更改为 1.9.3 以来我使用的 Ruby 版本有关。有什么想法吗？

试试bundle install 不带sudo。
