Install Rmagic / ImageMagic on win8

问题

My Rmagic gem stopped working. So i am attempting to re-install everything to get it working again.

The steps I have done so far.

Downloaded different versions to test with

ImageMagick-6.6.7-0-Q16-windows-dll.exe
ImageMagick-6.8.9-8-Q16-x64-dll.exe
ImageMagick-6.8.9-9-Q16-x64-dll.exe

Installed in a path without any spaces

"C:\RailsInstaller\ImageMagick"

Installed with path and header settings ticked

Opened cmd with admin access and ran

set CPATH=C:/RailsInstaller/ImageMagick/include
set LIBRARY_PATH=C:/RailsInstaller/ImageMagick/lib

tried to install

gem install rmagick

I get the error message

C:\Sites\website>gem install rmagick

回答1:

after re-installing and trying the following version worked for me

Ruby 1.9.3
ImageMagic 6.6.7-0 Q15

I also ran this command which installed rmagic successfully

gem install rmagick --platform=ruby -- --with-opt-dir=C:\RailsInstaller\ImageMagick
