Ruby 查找gem文件的问题？

我正试图按照教程构建一个Ruby Gem，但是我无法配置rspec，因为它无法找到我的Gem

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

$ rake spec

我认为这可能与使用rvm有关，也可能与前面提到的教程中配置rake文件的方式有关，但我不确定

是什么导致了这个问题

这似乎是从

spec\u helper.rb

文件中的

require

中冒出来的。你的主要宝石类别与你的宝石名称相同吗？您应该需要的是主类，而不是gem的名称。尝试将require语句更改为以下语句之一，看看是否得到不同的结果

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

---

我还将尝试从IRB请求该类，并查看它将在什么情况下工作。

当您构建gem并希望通过您需要提供的名称请求它时：

lib/gemname.rb

该文件中的内容不太重要，只需要您想要的内容，比如需要从中获取其他内容：

require 'gemname/nothing'

此文件也存在的位置：

lib/gemname/nothing.rb

必须是那个教程吗？你试过其他的吗？我最常见的问题是文件不在我的$PATH中。
