Question

我在尝试运行任何Ultrasphinx rake命令（在Linux终端下）时遇到此错误，例如rake ultrasphinx：configure：

rake aborted!
no such file to load -- echoe
/var/www/gitorious/vendor/plugins/ultrasphinx/Rakefile:2:in `require'
/var/www/gitorious/vendor/plugins/ultrasphinx/Rakefile:2
/usr/lib/ruby/1.8/rake.rb:2359:in `load'
/usr/lib/ruby/1.8/rake.rb:2359:in `raw_load_rakefile'
/usr/lib/ruby/1.8/rake.rb:1993:in `load_rakefile'
/usr/lib/ruby/1.8/rake.rb:2044:in `standard_exception_handling'
/usr/lib/ruby/1.8/rake.rb:1992:in `load_rakefile'
/usr/lib/ruby/1.8/rake.rb:1976:in `run'
/usr/lib/ruby/1.8/rake.rb:2044:in `standard_exception_handling'
/usr/lib/ruby/1.8/rake.rb:1974:in `run'
/usr/bin/rake:28

我收集这意味着没有安装echoe gem。但如果我运行“gem list --local”，它会显示已安装echoe gem。这可能是什么问题，我该如何调试呢？

Answer 1

您是否尝试升级echoe版本？

sudo gem update echoe

很奇怪。所有的ultrasphinx任务都在.rake文件中正确定义，该文件应由Rails加载而不通过插件Rakefile文件。

还要确保你运行

rake ultrasphinx:configure

Ruby on Rails：即使安装了gem也找不到它
