Question

我碰巧有一些旧的rails项目，它的rails 3.2和ruby 2.2.4。因此，安装一些宝石失败了，特别是它的rmagick -v＆＃39; 2.13.2＆＃39;＆＃34;。

    $ gem install rmagick -v '2.13.2'
    Building native extensions.  This could take a while...
    ERROR:  Error installing rmagick:
            ERROR: Failed to build gem native extension.

        /home/user123/.rubies/ruby-2.2.4/bin/ruby -r ./siteconf20160826-3014-1j0i394.rb extconf.rb
    checking for Ruby version >= 1.8.5... yes

    Can't install RMagick 2.13.2.
    RMagick does not work when ImageMagick is configured for High Dynamic Range Images.
    Don't use the --enable-hdri option when configuring ImageMagick.

    *** extconf.rb failed ***
    Could not create Makefile due to some reason, probably lack of necessary
    libraries and/or headers.  Check the mkmf.log file for more details.  You may
    need configuration options.

    Provided configuration options:

    extconf failed, exit code 1

    Gem files will remain installed in /home/user123/.gem/ruby/2.2.4/gems/rmagick-2.13.2 for inspection.

我已经尝试过对图书馆＆＃34; ImageMagick＆＃34;安装一个没有hdri，但即便失败，因为还有其他依赖于＆＃34; ImageMagick＆＃34;使用hdri，因此我无法重新安装它。通常，仅为单个rails项目重新安装库并不是一件合适的事情。

那么你会推荐我什么？我在Arch Linux上安装了2个红宝石：

$ chruby
 * ruby-2.2.4
   ruby-2.3.1

也许我应该将它升级为更新版本？请注意，我不想破坏项目中的其他依赖项。

你可以在另一个位置安装非HDRI库，并确保首先找到它的Magick-config：

PATH="/alternative-path-you-choose/ImageMagick-6.8.9/bin-Q16:$PATH" gem install rmagick -v '2.13.2'

无法安装旧版本的宝石＆＃34; rmagick＆＃34;
