On Windows, you should use the rmagick-win32 gem.
http://rmagick.rubyforge.org/install-faq.html#win

You can get rmagick to compile on Windows with the command:
gem install rmagick -- '--with-opt-dir="[path to ImageMagick]"'
There are three noteworthy things about this command:
There's a double-dash separating "rmagick" and the --with-opt-dir option
The --with-opt-dir option is surrounded by single-quotes
The path to the ImageMagick directory is surrounded by double-quotes
You can have spaces in the path to the ImageMagick directory if you use this syntax. I think the path also doesn't care about forward or backward slashes, but I use backslashes.
You also have to make sure of two other things:
ImageMagick was installed with the development headers option (installs lib and include directories)
ImageMagick is first in your system path
If ImageMagick isn't first in your system path, you'll get an "Invalid drive specification" error when extconf.rb tries to identify the ImageMagick version.
All that said, I've experienced failures to build with some version pairings of rmagick and ImageMagick. I was able to get ImageMagick 6.7.7 and rmagick 2.13.1 to build together on both Windows 7 and Server 2003.

Download this rmagick-2.13.2.gem gem and save in you local.
Open the repository in cmd prompt where the gem file is located and run the following cmd
gem install rmagick-2.13.2.gem --platform=ruby --with-opt-lib=C:/ImageMagick-6.6.7-Q16/lib --with-opt-include=c:/ImageMagick-6.6.7-Q16/include

A simple google search yielded one very promising result: rmagick on windows. By the way, I guess you are using something like Ruby 1.8.5/1.8.7, but surely not 3.3.5 ( if you do, please let me join you in your time-travel adventures. We could be friends! )

Bundler v2.0.2 refuses to install libxml-ruby 3.1.0 on Mac OS Catalina

I have found all of the answers of how to install libxml-ruby with the gem install command:
gem install libxml-ruby -v '3.1.0' -- --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-lib=/usr/local/opt/libxml2/lib --with-xml2-include=/usr/local/opt/libxml2/include
Works beautifully! But then running this right afterward:
bundle install
gives the unhelpful error:
Fetching libxml-ruby 3.1.0
Installing libxml-ruby 3.1.0 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

--with-xml2-config
OK, it looks like the libxml2 options are not being included in the call the bundler uses to install. So let's do this:
bundle config build.libxml-ruby --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-lib=/usr/local/opt/libxml2/lib --with-xml2-include=/usr/local/opt/libxml2/include
That should work, right? Well no it doesn't. I am dead in the water until I can get Bundler to do what it is supposed to do.
There is no good answer for why Bundler fails here. The gem install line works. Bundler fails.
Inside the mkmf.log file is this:
find_header: checking for libxml/xmlversion.h in /opt/include/libxml2,/opt/local/include/libxml2,/usr/local/include/libxml2,/usr/include/libxml2... -------------------- no
And then several failures that all relate to not being able to find that header file.
It's looking in /opt/, instead of /usr/local/opt. I don't know how to make Bundler look in the correct place if it won't respect the bundle config commands.
Since Bundler wouldn't honor the paths I was passing in, I looked at the paths where it was looking for xmlversion.h.
I went into /usr/local/include. That's where all my Homebrew links are. I created a symlink to the Mac OS-provided libxml directory:
ln -s /usr/local/opt/libxml2/include/libxml2/libxml libxml
/usr/local/opt seems like a strange place for a system directory, but I'm tired of messing with it.
Once I did this, and went back into my app directory, bundle install worked. Well, I mean it broke again but it was on therubyracer this time. So it at least jumped this hurdle.

Unable to install rmagick on mojave

Went thru many blogs in stackoverflow inorder to install rmagick but didnt find a solution. Any help is much appreciated.
Tried using uninstalling and reinstalling imagemagick. Flow some links like Install rmagick
Here is the output

If you've installed Imagemagick per the instructions in your link, your shell may missing the path to the binaries. You can test by running a console command:
which MagickWand-config
If it returns a path (likely /usr/local/bin/MagickWand-config) your path is probably fine. If it returns MagickWand-config not found you should be able to type export PATH=/usr/local/bin:$PATH in your console.
If your path wasn't correct before, after running the export command you can re-run the which MagickWand-config command to confirm it's in your path. Then try to gem install rmagick again.
I was able to install rmagick on Mojave following the link you posted.
If this did fix your issue you'll also want to add the export command I noted in your ~/.bash_profile or ~/.zsh_profile file so that path is prepended in every terminal window (if it's not there already)

Rugged gem installation issue possibly with libgit2 on Windows

I am using Windows and my Gemfile has this line:
gem 'rugged'
When I run bundle install it's giving me this error:

An error occurred while installing rugged(0.21.0), and Bundler cannot continue.
Make sure that `gem install rugged -v '0.21.0'` succeeds before
bundling.
I'm guessing it has something to do with libgit2 but I'm not sure.
This is actually a question I'm surprised isn't asked more. But rugged requires CMake & pkg-config in order to compile correctly.
Just because we can, we will extract them into the DevKit itself.
First let's grab a copy of each:
CMake is fairly straight forward, here's the download link.
pkg-config is a little bit more complicated, it has some dependencies and such. However, there's a nice package bundled with the dependencies.
Then Extract the proper files into the DevKit
Once you have them you need to open up each archive(requires 7-zip) and open the top level folder in the archive.
From there you need extract the bin and share directories from the archive into the DevKit root directory.
It should just merge the directories into the existing ones and nothing should be overwritten or deleted.
Try installing again and it should just work and you don't dirty your PATH with more stuff.

Thank you in advance for your help
You need to install Ruby DevKit if on windows, get it from: http://rubyinstaller.org/downloads/ (scroll down a little).
Same story here deleting ruby and installing:
Ruby 2.0.0-p247
DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe
from http://rubyinstaller.org/downloads/ solved the problem.
Try to use railsinstaller from http://railsinstaller.org/
it will install follwing
Ruby 1.9.3-p392
Rails 4
Bundler
Git
Sqlite
TinyTDS
SQL Server Support
DevKit
The same can happen when you try to combine 32-bit Ruby and 64-bit DevKit.
The solution is to use same-bit versions.
For instance current versions:
rubyinstaller-2.0.0-p247-x64.exe
DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe

Install hpricot on Mac OS X with rvm and brew

Thoughts? Suggestions? Thanks!

ERROR: Failed to build gem native extension. and checking for stdio.h... no are suspicious. Hpricot, along with many other Ruby gems, needs to compile some code and will fail if the development package is missing.
You are running RVM and 1.8.7 is in ~/.rvm on your machine, so it looks like it is because RVM would have to compile Ruby, but the failure sounds like it isn't. Do you have Apple's XCode installed in the /Developer directory? If you didn't install it and/or the directory isn't there, you can find the installer on your MacOS install discs, or at Apple's Developer site: http://developer.apple.com/technologies/xcode.html
That aside, I'd recommend using Nokogiri over Hpricot. I ran into several bugs in Hpricot a while back that made it unusable for my needs, and switched to Nokogiri. You'll find the two gems have similar syntax. http://nokogiri.org/
Turns out this was an XCode version dependency. Updating XCode to 3.2.4 resolved this.
