我还没有使用该 gem 的任何经验，但我希望这可以帮助您跟踪您的 rdoc 和 ri doc 路径。

gem env

在我的Mac系统上，我从安装目录找到了这条路径

/opt/experiment/ruby/lib/ruby/gems/1.9.1/doc/

，当我打开它（或在Windows中探索）时，我看到了一些gems的rdoc /ri doc 在此路径内。尝试删除那里的 gem 文档。如果可以的话请告诉我，它在我的 Mac 上可以正常工作。

下次当您安装 ruby​​gems 但不想安装 ri/rdoc 时，请记住在执行 gem install Something--no-rdoc --no-ri 选项>

作为参考比较，我只需将我的 gem env 复制粘贴到此处

. gem env

更新 (7/28/2019)：--no-ri --no-rdoc 不再工作 Rubygems >= 2.0。或者，您可以使用 --no-document 省略文档。
