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

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'

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
