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 :
耙中止! 没有要加载的文件——回显 /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:在“运行”中 /usr/lib/ruby/1.8/rake.rb:2044:in `standard_exception_handling' /usr/lib/ruby/1.8/rake.rb:1974:在“运行”中 /usr/bin/rake:28
我收集这意味着未安装 echo gem。但是如果我运行“gem list --local”,它会显示 echoe gem 已安装。这里可能是什么问题,我该如何调试?
