问题:

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' /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' /home/tpeg/rails_apps/Test/Rakefile:8 /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/rake_module.rb:25:in `load' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/rake_module.rb:25:in `load_rakefile' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:495:in `raw_load_rakefile' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:78:in `load_rakefile' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:129:in `standard_exception_handling' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:77:in `load_rakefile' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:61:in `run' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:129:in `standard_exception_handling' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/lib/rake/application.rb:59:in `run' /usr/lib/ruby/gems/1.8/gems/rake-0.9.2/bin/rake:32 /usr/bin/rake:19:in `load' /usr/bin/rake:19

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
