No source for ruby-2.0.0-p451 provided with debugger-ruby_core_source gem

Answer 1

Try install debugger without specifying a version and then run bundle install again.

I had the same error, and it just worked, don't ask me why:

$ gem install debugger
$ bundle install

Answer 2

there seems to be a problem with the compatibility of ruby version and debugger gem of rails. Running the below command worked for me:

 rvm ruby-2.0.0-p481

If it doesn't work type

 rvm list

will get a list of ruby version. Select an older ruby version, which might work.

Answer 3

I ran into what I believe was the same problem while trying to install dubugger with ruby 2.0.0-p598.

The gem debugger-ruby_core_source is a dependency of debugger and provides header files for specific versions of ruby that seem to be used while installing debugger. Look in debugger-ruby_core_source/lib/debugger/ruby_core_source/ to see which versions are supported—the header files are not provided for all ruby versions. In my case, they were not provided for version 2.0.0-p598.

Looking at the README for debugger-ruby_core_source, there is a rake task for adding the required files for ruby versions.

From the command line within the gem's directory, I ran

$ rake add_source VERSION=2.0.0-p598 

When I ran this task the first time, I received an error and was required to install the archive-tar-minitar gem before running the rake task again.

After the rake task added the header files for my version, I was able to successfully install and run debugger.
