Question

我正在尝试在this教程之后构建Ruby Gem，但我无法配置rspec，因为它无法找到我的gem。

$ gem list | grep gemname
gemname (0.0.1.alpha)

$ rake spec
/Users/rudolph9/.rvm/rubies/ruby-1.9.3-p0/bin/ruby -S rspec ./spec/gemname_spec.rb

我这可能与使用rvm或者前面提到的教程中配置rake文件的方式有关，但我不确定。

造成这个问题的原因是什么？

Answer 1

看起来这是从require文件中的spec_helper.rb冒出来的。您的主要宝石类是否与宝石的名称相同？你应该要求主类而不是宝石的名字。尝试将require语句改为以下之一，看看是否得到了不同的结果。

require 'gemname'
# Or
require 'gemname.rb'
# Or
require './path/to/gemname.rb'

我还会尝试从IRB中要求该课程，看看它会起作用的情况。

Answer 2

当您构建一个gem并希望通过它的名称来命名时，您需要提供：

lib/gemname.rb

这个文件中的内容不太重要，只是你想要的其他内容：

require 'gemname/nothing'

此文件也存在：

lib/gemname/nothing.rb

定位gem文件的问题？
