在Windows上安装适用于Ruby on Rails的ImageMagick时出错 [英] Error while installing ImageMagick for Ruby on Rails on Windows

问题描述

我在rails上安装ruby并使用xampp redmine以下文档：

I'm installing ruby on rails and redmine with xampp following this documentation:

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

第12步需要安装rmagick，我按照步骤操作正确到达12-d：

Step 12 requires installing rmagick, I followed the steps correctly till I reached 12-d :

在cmd窗口中，运行以下命令：

In the cmd window, run the following:

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

我收到以下错误：

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

我下载了ImageMagick-devel-6.8.9.9.aarch64.rpm cz它可能解决了我的问题，但我不知道如何安装它。请问有什么想法吗？

I downloaded ImageMagick-devel-6.8.9.9.aarch64.rpm cz it might solve my problem but I don't know how to install it. Any ideas please?

推荐答案

听起来你在安装ImageMagick之前想要安装RMagick gem：

Sounds like you're trying to install the RMagick gem before installing ImageMagick:

RPM适用于某些Linux发行版。

The RPM is for certain Linux distributions.

尝试安装 http://www.imagemagick.org/ script / binary-releases.php #windows 然后是gem。

Try installing http://www.imagemagick.org/script/binary-releases.php#windows then the gem.
