Installing RMagick on Windows

问题

I've done research on this and I've been at it on my one computer for hours and hours.

I've installed RMagick on my Desktop computer about 3 weeks ago, and it was fairly complicated.

I don't remember the exact steps I took, and I'm really frustrated.

I've installed ImageMagick onto my machine in the directory C:\ImageMagick

I've installed the Development kit too for Ruby.

I've also put the rmagick-rmagick-v2-2-g564f157 into the proper gems folder in my C: It's in C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems

I'm getting the following errors:

I will type: gem install rmagick -- '--with-opt-dir="c:\ImageMagick"'

and get the following errors:

Temporarily enhancing PATH to include DevKit...

I'm so frustrated at this point. It worked on my Desktop computer, but won't work here. Any suggestions?

This is the one link which can help you with all the issues you will ever face while installing rmagick gem.

Found it after a lot of browsing and after it you might not need any other link to visit.

I hope it will save your time and efforts

What I do to install is the following:

Install ImageMagick with installer including (!) "development headers and libraries" See: http://www.graphity-consulting.com/files/2016/03/screenshot-installation-imagemagick-6.9.3-32bit-3.png
Open windows command prompt
Enhance path to include ImageMagick. E.g. set PATH=d:\opt\ImageMagick;%PATH%
Install gem using: gem install rmagick -- --with-opt-dir=d:\opt\ImageMagick

Note: I let gem download rmagick by itself and I pass path to ImageMagick in --with-opt-dir and also have it in my path.

UPDATE:

As @winter-young mentioned in comments: Do not mix 32 Bit ruby with 64 Bit ImageMagick or vice versa. Only use 32 Bit ruby with 32 Bit ImageMagick. Or use 64 Bit ruby with 64 Bit ImageMagick.

UPDATE 2

As @winter-young states, rmagick 2.15.4 only supports ImageMagick 6, not ImageMagick 7 (didn't test it myself)

UPDATE 3

As @tiefenauer points out, rmagic 2.16.0 works with ImageMagick 7.0.8. Furthermore, single quotes are needed now: gem install rmagick -- '--with-opt-dir=C:\Program Files\ImageMagick-7.0.8-Q16'
