CommandT installation problems on windows - vim

Question

After completing all installation steps for the CommandT plugin, I get the error command-t.vim could not load the C extension when starting it. The ComamndT troubleshooting section gives this advice:
If a problem occurs the first thing you should do is inspect the output of:
ruby extconf.rb
make
During the installation, and:
vim --version
And compare the compilation and linker flags that were passed to the
extension and to Vim itself when they were built. If the Ruby-related
flags or architecture flags are different then it is likely that something
has changed in your Ruby environment and the extension may not work until
you eliminate the discrepancy.
And it does indeed seem that there is discrepancy for me.
Output from make suggests cygwin's gcc is using ruby 1.8:
gcc -I. -I/usr/lib/ruby/1.8/i386-cygwin -I/usr/lib/ruby/1.8/i386-cygwin -I. -DHA
VE_RUBY_H -g -O2 -std=c99 -Wall -Wextra -Wno-unused-parameter -c ext.c
gcc -I. -I/usr/lib/ruby/1.8/i386-cygwin -I/usr/lib/ruby/1.8/i386-cygwin -I. -DHA

e-auto-image-base,--enable-auto-import,--export-all -lruby -ldl -lcrypt
Output from vim's :version contains this output:
-DDYNAMIC_RUBY_VER=191 -DDYNAMIC_RUBY_DLL=\"msvcrt-ruby191.dll\"
The troubleshooting guide suggests using a combination of Vim 7.2, Ruby 1.8.7-p299, and DevKit 3.4.5r3-20091110. However this is not a good solution for me for a number of reasons:
I'm using Vim 7.3 and would like to continue doing so.
Ruby 1.9.3 is installed on my system, and I need it in my PATH for other projects.
So is there any way to get this working, while keeping the latest version of ruby and the latest version of vim?
UPDATE
Having followed AndrewMarshall's advice, I installed Ruby191 and DevKit-4.5.0-20100819-1536-sfx.exe according to this tutorial and ran ruby extconf.rb through that version. The make cmd executed successfully with this output:
gcc -I. -IC:/Ruby191/include/ruby-1.9.1/i386-mingw32 -I/C/Ruby191/include/ruby-1

and running :CommandT in vim works now, but as soon as I start typing to search for a file, and then hit enter to select and open it, I get this:

Answer 1

not a real answer but you may wanna try ctrlp instead.
written in vimscript (no dependency, no compiling)
as fast as CommandT (subjective to me)
has probably more features than CommandT (does CommandT have most recent file?)
there is also the good old FuzzyFinder which I haven't tried. seems like it hasn't got updated for about 2 years but it may still be working.

Answer 2

I successfully installed newest command-t on vim 8.0 on windows 10. And I find this question when I'm working on it so I'm gonna post my solution although it's a little late.
Ruby version for vim 8.0 is Ruby 2.2. So download and install Ruby 2.2 and Ruby Devkit (remember to execute ruby dk.rb init and ruby dk.rb install for devkit ).
Then I follow the command-t instruction to execute ruby extconf.conf, but it failed -- it output You have to install development tools first. even though I did install it:
I googled this issue find RubyInstaller wiki says that I should execute this command by add -rdevkit and I did it. It succeed when I execute ruby -rdevkit extconf.rb but failed when make. So I googled again and find another way to compile it:
rake make -rdevkit
And it worked. Here is my screenshot:
