rmagick install extconf.rb error

Question

Hi I'm trying to install rmagick for like 10 hours, the frustration is immense..

So here follows:

c:\>ruby -v
ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32]

c:\>rails --version
Rails 5.0.0

c:\>gem --version
2.4.5.1

c:\Ruby22\bin>convert -version
Invalid drive specification.

c:\ImageMagick-6.9.5-Q16>convert -version

and finally when im trying to install (i also have DevKit)

c:\Ruby22>gem install rmagick -- --with-opt-dir=c:\ImageMagick-6.9.5-Q16
Temporarily enhancing PATH to include DevKit...

I've tried many many solutions , nothing works , just keep getting this error.

I messed with %PATH% ,tried different versions , read all the instructions , tried in 2 different machines. It seems impossible for me..

the suggested duplicate offers obsolete links that lead nowhere, even if it is a duplicate of an answered question , that answer is not up to date and offers no good. I truly wish that could help , but i came across that answer a while ago...

It seems a mistake in the path `--with-opt-dir=c:\ImageMagick-6.9.5-Q16` Just an opinion: I recommend you change OS for avoiding such nondeterministic errors — user1201917, Jul 25 '16 at 16:46

umm there's not even a file called like that anymore, maybe what you say about windows .. maybe i should go to ubuntu.. but darn this installation is so broken ... and about the path , i've seen so many write it this way , it's just the way gem wants it :S — Ml Ck, Jul 25 '16 at 17:10
