Question

我正在尝试在ruby文件上运行rake，我应该收到错误，所以我可以调试它作为练习。然而，我得到的错误不是我应该收到的错误。我收到以下内容，我有时间解释我需要解决的问题。

~Desktop/learn_ruby-master/00_hello$ rake
(in /~Desktop/learn_ruby-master)
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file --     hello (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from ~Desktop/learn_ruby-master/00_hello/hello_spec.rb:117:in `<top (required)>'
    from /var/lib/gems/1.9.1/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load'

rake aborted！

这是我正在运行的代码

    require "hello"

describe "the hello function" do
  it "says hello" do
    hello.should == "Hello!"
  end
end

describe "the greet function" do
  it "says hello to someone" do
    greet("Alice").should == "Hello, Alice!"
  end

  it "says hello to someone else" do
    greet("Bob").should == "Hello, Bob!"
  end
end

Answer 1

我遇到了同样的问题（通过完全相同的教程）。我只花了三天时间试图解决这个问题。问题是我的'hello.rb'路径中的一个文件夹在两个单词之间有一个空格。说真的，就是这样。无论我做了什么（除了改变空间），红宝石路径都无法捡起它。 Uggh。经验教训，不要在任何地方命名任何东西，从这里开始有空间。

Answer 2

Ruby说的一切：“在库加载路径上找不到文件名hello.rb”。你缺少hello.rb文件或Ruby无法找到它。你真的把它放在你运行rake的目录中的光盘上吗？如果它在其他地方你需要提供相对路径。

同样从第一行删除空格，我怀疑你有一些gargabe。错误消息中的 - 和hello之间应该只有一个空格。
