为什么我会收到此 Rake 错误：

$ rake --version
/Volumes/Data/sampablokuper/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rake (>= 0) amongst [] (Gem::LoadError)
    from /Volumes/Data/sampablokuper/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'
    from /Volumes/Data/sampablokuper/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems.rb:1231:in `gem'
    from /Volumes/Data/sampablokuper/.rvm/gems/ruby-1.9.3-p194/bin/rake:18:in `<main>'

    from /Volumes/Data/sampablokuper/.rvm/gems/ruby-1.9.3-p194/bin/ruby_noexec_wrapper:14:in `<main>'

鉴于以下情况：

$ gem list

*** LOCAL GEMS ***

bundler (1.1.3)
rake (0.9.2.2)
rubygems-bundler (1.0.2)
rvm (1.11.3.3)
$ which rake
/Volumes/Data/sampablokuper/.rvm/gems/ruby-1.9.3-p194/bin/rake

具体来说：此错误消息是源于错误还是配置问题（如果是后者，那么哪些步骤可以解决它）？

更新：根据要求附加终端输出：

$ which gem
/Volumes/Data/sampablokuper/.rvm/rubies/ruby-1.9.3-p194/bin/gem
$ whereis rake
/usr/bin/rake
$ echo $PATH # I've edited the output as one item per line for easier reading

'whereis' 二进制文件检查一组由 user.cs_path 变量设置的系统默认路径（请参阅 参考资料sysctl -a | grep user.cs_path），而不是实际的 $PATH 变量。因此，报告的“rake”位置将始终是该组路径中发生的任何内容，而不是实际使用的路径，除非确实恰好是系统上安装的唯一rake，因此不会出现在 $PATH 中。

请运行

which rake

查看实际使用的是哪个 rake。如果它报告 /usr/bin/rake 而不是 /Users/me/.rvm/gems/ruby-1.9.3-p194@global/bin/rake 之类的路径，那么肯定有问题。

请包括

rvm info

输出并确保

type rvm | head -n1

报告“rvm 是一个函数”。如果它报告了除此之外的任何内容，那么您的安装就搞砸了，在这种情况下，您应该使用 删除您的 rvm 安装rvm implode，完全注销，然后完全重新安装 RVM。是的，注销步骤很重要。

看起来问题似乎正在发生，因为在我执行问题中显示的命令的目录中存在一个名为Gemfile以下内​​容的文件：

source 'https://rubygems.org'

gemspec

删除或重命名该文件会产生以下结果（耶！）：

$ rake --version
rake, version 0.9.2.2

相比之下，保留 Gemfile，但从myproject.gemspec目录中删除或重命名文件会产生以下结果：

$ rake --version
/Volumes/Data/sampablokuper/.rvm/gems/ruby-1.9.3-p194/gems/bundler-1.1.4/lib/bundler/dsl.rb:48:in `gemspec': There are no gemspecs at /Volumes/Data/spikes/myproject. (Bundler::InvalidOption)

的行为rake --version受到这些文件的存在/不存在/内容的强烈影响这一事实确实让我觉得是一个错误，我将相应地提交一份错误报告。
