Question

我有一个我复制到我的机器的rails应用程序。我在访问应用程序时遇到以下错误。

    MissingSourceFile (no such file to load -- xml):
    app/controllers/results_controller.rb:6
    /usr/local/rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/webrick/httpserver.rb:104:in `service'

   /usr/local/rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/webrick/server.rb:82:in `start'

我尝试安装libxml，收到以下错误：

  [root@localhost log]# gem install libxml-ruby
  WARNING:  RubyGems 1.2+ index not found for:
  RubyGems will revert to legacy indexes degrading performance.
  ERROR:  Could not find a valid gem 'libxml-ruby' (>= 0) in any repository
  [root@localhost log]#

如何解决此问题？

Rails版本：2.3.8 Ruby版本：1.8.7 操作系统：FC18

该错误意味着您的用户无法解析libxml-ruby的宝石来源。 libxml-ruby似乎也由rubygems.org托管。因此，您可以将https://rubygems.org添加到您的源并安装gem。

# gem sources -a https://rubygems.org
https://rubygems.org added to sources

然后安装libxml-ruby：

# gem install libxml-ruby

这应该成功安装gem。

要查看可用来源列表，您可以发出gem sources：

# gem sources

错误：找不到有效的宝石＆＃39; libxml-ruby＆＃39; （＆gt; = 0）
