ruby – 在UTF-8中使用无效的字节序列

出乎意料的是,我在运行rails 3.2和 Ruby 1.9.3p125的网络服务器上的任何rake命令都遇到了一个奇怪的错误,无论什么样的rake任务,堆栈跟踪都是一样的.除了Rakefile和lib / tasks中的ascii之外什么都没有.

堆栈跟踪：

rake --trace
rake aborted!
invalid byte sequence in UTF-8
/usr/local/lib/ruby/1.9.1/rake/application.rb:183:in `glob'
/usr/local/lib/ruby/1.9.1/rake/application.rb:183:in `block in have_rakefile'
/usr/local/lib/ruby/1.9.1/rake/application.rb:181:in `each'
/usr/local/lib/ruby/1.9.1/rake/application.rb:181:in `have_rakefile'
/usr/local/lib/ruby/1.9.1/rake/application.rb:468:in `find_rakefile_location'
/usr/local/lib/ruby/1.9.1/rake/application.rb:486:in `raw_load_rakefile'
/usr/local/lib/ruby/1.9.1/rake/application.rb:82:in `block in load_rakefile'
/usr/local/lib/ruby/1.9.1/rake/application.rb:133:in `standard_exception_handling'
/usr/local/lib/ruby/1.9.1/rake/application.rb:81:in `load_rakefile'
/usr/local/lib/ruby/1.9.1/rake/application.rb:65:in `block in run'
/usr/local/lib/ruby/1.9.1/rake/application.rb:133:in `standard_exception_handling'
/usr/local/lib/ruby/1.9.1/rake/application.rb:63:in `run'
/usr/local/bin/rake:32:in `<main>'

有问题的方法是

def have_rakefile
      @rakefiles.each do |fn|
        if File.exist?(fn)
          others = Dir.glob(fn,File::FNM_CASEFOLD)
          return others.size == 1 ? others.first : fn
        elsif fn == ''
          return fn
        end
      end
      return nil
    end

由于堆栈跟踪对我没有帮助,我在块的开头插入了一个put“#{fn}#{File :: FNM_CASEFOLD}”并得到了：

rakefile 8
Rakefile 8

/usr/local/lib/ruby/1.9.1/rake/application.rb:63:in `run'
/usr/local/bin/rake:32:in `<main>'

rakefile只是rails生成的默认文件

# Add your own tasks in files placed in lib/tasks ending in .rake,# for example lib/tasks/capistrano.rake,and they will automatically be available to Rake.

require File.expand_path('../config/application',__FILE__)
require 'rake/dsl_definition'
require 'rake'

MyApp::Application.load_tasks

lib / tasks中唯一的任务文件是

desc "Resets the help files in the db by deleting all existing and rereading the yaml files"
    task :help_reset => :environment do
      HelpSystem.delete_all
      HelpSystem.seed_help
    end

我不知道下一步该去哪里,非常感谢任何帮助.
