Failing to install ruby-debug-ide gem under ruby 2.1.2 - ruby

Question

I am trying to install the ruby-debug-ide gem under ruby 2.1.2 . This to debug in Rubymine.
It worked for ruby1.9.3 but not for this version.
here is the error:
1.3.5/lib/debugger/ruby_core_source/ruby-2.1.2-p95/***internal.h:209: error: expected ‘;’, ‘,’ or ‘)’ before ‘x’***
Here is the output.
I would love the ability to make sence or debug this in some way . A quick fix will also be great by the way :-)

Answer 1

The problem seems to be that the gem debugger-ruby_core_source can’t find the header file vm_core.h, which is part of Ruby’s source code. To install the source only (given that you have the binaries installed already) do:
$ rvm fetch ruby-2.1.2
You can also reinstall from source (a bit slower but it’s a good habit):
$ rvm reinstall ruby-2.1.2 --disable-binary
Update based on your additional error message
According to your message, you need to install OpenSSL:
$ brew install openssl
To sum up:
You can’t install debugger-ruby_core_source because it needs the
Ruby source for your Ruby version.
You can’t install the Ruby source
code with RVM because the Open SSL libraries are missing.
To remedy that type rvm autolibs homebrew so that RVM will install the missing packages if needed (you might need root permissions and enter your password when requested). This also lets RVM takes care of dependency problems from now on, you shouldn’t need to type the command again.

Answer 2

I had a similar issue, and installing the debugger-ruby_core_source gem manually before installing ruby-debug-ide worked.

Answer 3

I had this happen to me today, and solved it after running brew unlink openssl && brew link openssl --force
Hope it helps.
