我在安装Rmagick时遇到了一些问题。 有两种方法可以安装它： 1]使用Ruby-Gem 2]来源
我在这两方面都遇到了问题，但我希望能够获得宝石并安装。
我已经更新了PKG_CONFIG_PATH，但我仍然面临问题：
PKG_CONFIG_PATH=/home/<user>/Downloads/ImageMagick-6.7.5-7/magick gem install rmagick
Building native extensions. This could take a while...

necessary libraries and/or headers. Check the mkmf.log file for more

有什么建议吗？
更新： 我安装了libmagickwand-dev和libmagickwand2
P.S：我正在尝试使用Gruff，我想知道是否使用它也会像安装一样痛苦。我可能也会尝试rcharts而这个问题得到解决......答案 0 :(得分：0)
您将PKG_CONFIG_PATH设置为文件，而不是路径。以下应该工作：
PKG_CONFIG_PATH=/home/<user>/Downloads/ImageMagick-6.7.5-7/magick gem install rmagick
（虽然知道安装RMagick有多痛苦，但它仍然可能不起作用，如果没有，请随时发表评论。）

好吧，根据错误消息，您可能缺少libmagickwand-dev包。
如果您只是使用ubuntu：
sudo apt-get install libmagickwand-dev
