ruby - 为什么我得到 "RAKEFILE ABORTED, NO RAKEFILE FOUND"？

Question

我正在尝试进行交互式 Ruby 测试，但没有成功。

我毫无问题地下载了 zip 文件并按照说明进行操作我继续收到以下错误的终端命令行。我我正在使用“Ruby 1.9.3p392(2013-02-22 修订版 39386)[x86_64-darwin10.8.0]”。

如果有人可以提供任何帮助或建议，在此先感谢您。

INSTRUCTIONS:

Install RSpec

  gem install rspec

Enter the course directory. (That's the same directory that this
index.html file is in.)

  cd learn_ruby

Enter the 00_hello lab.

  cd 00_hello

Open a terminal in this directory

cd 00_hello

This directory is the starting point for this exercise. It contains a
spec file and you'll be adding a ruby file to (eventually) make the
specs pass.

Run the test

  rake

Watch it fail

You should see an error. Don't get scared! Try to read it and figure out
what the computer wants to tell you. Somewhere on the first line it
should say something like

no such file to load -- test-first-teaching/hello/hello (LoadError)

我没有收到此错误消息，我收到以下错误消息:

rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb,
Rakefile.rb)

/usr/local/rvm/gems/ruby-1.9.3-p392/bin/ruby_noexec_wrapper:14:in

(See full trace by running task with --trace)

当我运行 rake --trace 时，我收到:

在运行 rake routes 之前你必须进入你的项目目录
