windows windows下的rmagick

rmagick under windows

提问by Joern Akkermann

I just wanted to install rmagick under windows.

我只是想在 windows 下安装 rmagick。

So I installed ImageMagick with C/C++ header, but that seems no more to be necessary.

所以我安装了带有 C/C++ 头文件的 ImageMagick，但这似乎没有必要了。

Then I installed the Ruby Build Tools

然后我安装了 Ruby Build Tools

ruby dk.rb init
ruby dk.rb install

Then I wanted to install the rmagick gem with gem install rmagick.

然后我想用gem install rmagick.

But I get this error:

但我收到此错误：

H:\Downloads\ruby build tools>gem install rmagick

Before I installed the Build Tools, I just got the advice to install them.

在我安装构建工具之前，我只是得到了安装它们的建议。

Now they are installed and I get a different error message than before (see above).

现在它们已安装，我收到与以前不同的错误消息（见上文）。

It still wants me to install the Build Tools, so its installation might be broken?

它仍然要我安装构建工具，所以它的安装可能会损坏？

I get the same error with linecache... also something with the mkmf file and build tools.

我在使用 linecache 时遇到了同样的错误......还有一些与 mkmf 文件和构建工具有关的错误。

I guess this is a common error.

我想这是一个常见的错误。

I installed ImageMagick and RMagick on Windows Vistain a Railsenvironment this way:

我通过以下方式在Rails环境中的Windows Vista上安装了 ImageMagick 和 RMagick ：

First I downloaded ImageMagick-6.6.7-Q16from http://www.imagemagick.org/download/binaries/and installed it in "C:\ImageMagick-6.6.7-Q16" folder.

首先，我从http://www.imagemagick.org/download/binaries/下载了ImageMagick-6.6.7-Q16并将其安装在“C:\ImageMagick-6.6.7-Q16”文件夹中。

Then I downloaded RMagick from https://github.com/rmagick/rmagick/zipball/masterand extracted it into "C:\RailsInstaller\Ruby1.9.2\lib\ruby\gems\1.9.1\bundler\gems\rmagick-rmagick\" folder (which is my ruby bundler gems folder).

然后我从https://github.com/rmagick/rmagick/zipball/master下载了 RMagick并将其解压到“C:\RailsInstaller\Ruby1.9.2\lib\ruby\gems\1.9.1\bundler\gems\rmagick- rmagick\" 文件夹（这是我的 ruby​​ bundler gems 文件夹）。

Then I simply called

然后我简单地打电话

'gem install rmagick' 

from my prompt and it all worked fine.

根据我的提示，一切正常。

Now I can call from a Rails app Gemfile

现在我可以从 Rails 应用 Gemfile 调用

gem "rmagick"

And then 'bundle install' works fine.

然后“捆绑安装”工作正常。

PS: please note that I first installed Rails with http://www.railsinstaller.org.

PS：请注意，我首先通过http://www.railsinstaller.org安装了 Rails 。

I had to install Ruby on Rails first, and then from the Command Prompt with Ruby and Rails, I ran:

我必须先安装 Ruby on Rails，然后从带有 Ruby 和 Rails 的命令提示符运行：

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

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

It all worked, and I saw this:

这一切都奏效了，我看到了这一点：

Windows 7 64bit, but installed the 32-bit version of ImageMagick to C:\ImageMagick

I got also the same error checking for stdint.h...The problem was that I've installed ImageMagick on C:\Program Files (x86)\ImageMagickwhich contains spaces. So I deinstall ImageMagick and installed again to C:\Ruby19\ImageMagick.

我也遇到了同样的错误checking for stdint.h...问题是我已经安装了C:\Program Files (x86)\ImageMagick包含空格的ImageMagick 。所以我卸载了 ImageMagick 并再次安装到C:\Ruby19\ImageMagick.

Here is what I've done (Ruby 1.9.3, mingw32)

这是我所做的（Ruby 1.9.3，mingw32）

1. Download ImageMagick-6.7.7-9-Q8-windows-dll.exe(the newest version of ImageMagick seems to be incompatible with rmagick)
2. Install to C:\Ruby19\ImageMagick. The path must not contain spaces!
3. Set install configuration to
   • Add application direcotry to your system path
   • Install development headers and libraries for C and C++
4. gem install rmagick --platform=ruby -- --with-opt-dir=C:\Ruby19\ImageMagick

1. 下载ImageMagick-6.7.7-9-Q8-windows-dll.exe（最新版本的ImageMagick好像和rmagick不兼容）
2. 安装到C:\Ruby19\ImageMagick. 路径不能包含空格！
3. 将安装配置设置为
   • 将应用程序目录添加到您的系统路径
   • 安装 C 和 C++ 的开发头文件和库
4. gem install rmagick --platform=ruby -- --with-opt-dir=C:\Ruby19\ImageMagick

回答by Wirror Yin

Include the head files & lib files to your System Environment first:

首先将头文件和 lib 文件包含到您的系统环境中：

set CPATH=C:/Progra~2/ImageMagick-6.7.0-Q16/include
set LIBRARY_PATH=C:/Progra~2/ImageMagick-6.7.0-Q16/lib

Them, gem install ** will be done. ~.~

他们， gem install ** 将完成。~.~

I installed RMagick using these instructions. Note that it calls for Ruby 1.9.1, but works (for me anyway) on 1.9.2 (i386-mingw32). I recommend uninstalling/reinstalling ImageMagick using the version specified in the instructions.

我使用这些说明安装了 RMagick 。请注意，它需要 Ruby 1.9.1，但在 1.9.2 (i386-mingw32) 上工作（无论如何对我来说）。我建议使用说明中指定的版本卸载/重新安装 ImageMagick。

If possible try replacing RMagick with Mini_Magick, it aims to do the same thing but a different way. I had no luck with RMagick but Mini_Magick installed in the bundle

如果可能，请尝试用 Mini_Magick 替换 RMagick，它旨在以不同的方式做同样的事情。我没有使用 RMagick 但 Mini_Magick 安装在捆绑包中
