When I run
rake db:create
I receive this error
rake aborted!
no such file to load -- rdoc/task
(See full trace by running task with --trace)
Here is the --trace

I have rake 0.9.2 and rdoc 3.11 installed. I am running these commands in my app's directory.
回答1:
I had the same problem.
I solved it by adding gem 'rdoc'
to my Gemfile and then run bundle install
.
回答2:
If you're not using a Gemfile, it's likely that switching your line in your Rakefile from this:
require 'rake/rdoctask'
to this
require 'rdoc/task'
will work. It did for me.
Also try a
gem install rdoc
回答3:
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.
begin
require 'rake/rdoctask'
rescue
require 'rdoc/task'
end
回答4:
If you're working on an app without a Gemfile (like a legacy with rails 2.3 --), you can install the gem rdoc manually:
gem install rdoc
