【问题描述】：
我只是想为我的 gem 生成文档，在运行 rdoc 或 yard 时出现错误
undefined method `intern' for []:Array
发生了什么事？我正在尝试重新安装所有内容，并且我使用的是 ruby 2.3.1。另外，据我了解，您不能在数组上使用实习生，那么为什么 rdoc 和 yard 会尝试这样做呢？
编辑
我现在已经进一步调查，这与我的特定语法有关，因为我的设置适用于其他文件，而不是我的。如何检查哪个文件有语法问题？
RDoc 全栈跟踪（看起来与 YARD 跟踪相同，但我已将两者都包含在内）：

【问题讨论】：
-
你有更长的堆栈跟踪还是这样？
-
@maxpleaner 我已经为 rdoc 和 yard 添加了完整的堆栈跟踪。
-
奇怪，您确定您使用的是与您的文档语法相对应的最新版本吗？除此之外，我真的帮不了你。
-
@maxpleaner 你可以在跟踪中看到我的东西的版本号。
