Building native extensions. This could take a while...

ERROR: Error installing ruby-debug:

Could not create Makefile due to some reason, probably lack of

necessary libraries and/or headers. Check the mkmf.log file for more

details. You may need configuration options.

Provided configuration options:

Answer 1

It means it doesn't work with Ruby 1.9 yet.

Answer 2

Run: gem install ruby-debug19

Answer 3

I ran into the same problem. Following steps should get you through:

1. Install ruby using RubyInstaller
2. Install devkit

3. Install ruby-debug19 instead of ruby-debug.

   gem install ruby-debug19

Answer 4

I face the same issue. The last suggestion, about going to ruby 1.9 version of the gem, wont it require to have ruby 1.9 running ??

I am on 1.8.7 still, and have faced some issues with 1.9, and therefore want to stay on this version for the moment.

As suggested in another post, I dont have MS VC++ 6 as well, so that route is also closed for me.

Any other suggestions ?

Answer 5

Execute Below command and its works

C:\Users\Steve>gem install ruby-debug --platform=mswin32
