在Windows上安裝ImageMagick for Ruby on Rails時出錯

Question

我正在按照以下文檔在Xampp的Rails和Redmine上安裝ruby：

http://nlb-creations.com/2013/06/26/installing-ruby-on-rails-and-redmine-with-xampp-on-windows-7/

步驟12需要安裝rmagick，我正確地遵循了步驟，直到達到12-d：

在cmd窗口中，運行以下命令：

gem install rmagick --platform=ruby -- --with-opt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include

我收到以下錯誤：

    C:\xampp\htdocs\dev-ruby\redmine>gem install rmagick --platform=ruby -- --with-o
    pt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include

Provided configuration options:

        --curdir
        --ruby=C:/RailsInstaller/Ruby1.9.3/bin/ruby


Gem files will remain installed in C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9
.1/gems/rmagick-2.13.3 for inspection.
Results logged to C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/rmagick-2

我下載了ImageMagick-devel-6.8.9.9.aarch64.rpm cz，它可能可以解決我的問題，但是我不知道如何安裝。 有什么想法嗎？

聽起來您正在嘗試安裝ImageMagick之前先安裝RMagick gem：

RPM適用於某些Linux發行版。

嘗試安裝http://www.imagemagick.org/script/binary-releases.php#windows然后安裝gem。
