Solution for rake db:create

Rails
1

I ran into the following error:

WARNING: ‘require ‘rake/rdoctask’’ is deprecated. Please use
‘require ‘rdoc/tas k’ (in RDoc 2.4.2+)’ instead.
at /usr/lib/ruby/vendor_ruby/rake/rdoctask.rb
rake aborted!
uninitialized constant Gem

Following that advice (which I also found by searching the web for the
error message) got me nowhere, however:

rake aborted!
no such file to load – rdoc/task

anyone know the solution.

check ur rake gem version and rubygems if installed or not.

I guess, its a conflict with using mutiple versions of Rake Gem.

If you have many applications, which require different rake gem versions
to run…

Install RVM,

Do a rvm gemset create gemset_name

and then place appropriate gem versions of rake and other gems in those
project specific gemsets… to avoid conflicts…
