If you're not using a Gemfile, it's likely that switching your line in your Rakefile from this:
如果你没有使用 Gemfile，很可能是从你的 Rakefile 中切换你的行：
require 'rake/rdoctask'
to this
对此
require 'rdoc/task'
will work. It did for me.
将工作。它对我有用。
Also try a
也试试
gem install rdoc

You can actually trap for this in your Rakefile should you have different rake versions between environments. We are this way with older production applications.
如果环境之间有不同的 rake 版本，您实际上可以在 Rakefile 中为此设置陷阱。对于较旧的生产应用程序，我们采用这种方式。
begin
require 'rake/rdoctask'
rescue
require 'rdoc/task'
end

If you're working on an app without a Gemfile (like a legacy with rails 2.3 --), you can install the gem rdoc manually:
如果您正在开发一个没有 Gemfile 的应用程序（例如带有 rails 2.3 -- 的旧版），您可以手动安装 gem rdoc：
gem install rdoc
gem 安装 rdoc
