我正在MacOS上设置我的VM Ubuntu 18.04.03。给予：
Ubuntu 18.04.03 LTS
ImageMagick 6.9.7-4 Q16 x86_64 20170114 http://www.imagemagick.org
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]
Expected Rails version set in Gemfile is '4.2.7.1'
The system suggests to run gem install rmagick -v '2.13.2'
在终端中运行捆绑安装时，出现以下错误：

Make sure that `gem install rmagick -v '2.13.2' --source 'https://rubygems.org/'` succeeds before bundling.

已安装0颗宝石-无结果
sudo apt install imagemagick libmagickcore-dev libmagickwand-dev已安装0颗宝石-无结果
sudo apt install libmagickcore-dev当我运行gem rmagick install时没有任何反应-错误保持不变
UPD。mkmf.log说：
PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH"任何帮助将不胜感激
我实际上知道了。这对我的特殊情况有所帮助。谁知道，它可能会对其他人有所帮助。在项目目录中，我这样做了。
首先我运行find_executable: checking for Magick-config... -------------------- no
--------------------
Can't install RMagick 2.13.2. Can't find Magick-config in /home/i.k/.rvm/gems/ruby-2.1.2/bin:/home/i.k/.rvm/gems/ruby-2.1.2@global/bin:/usr/share/rvm/rubies/ruby-2.1.2/bin:/sbin:/bin:/usr/bin:/usr/local/bin:/snap/bin:/usr/share/rvm/bin
以确保我拥有它并且它位于应该存在的位置。
第二我跑了locate libMagick
我还在终端中运行了locate Magick-config，以确保我拥有Imagemagic并检查其版本。
为了安全起见，有人认为它并不总是预先安装在Ubuntu上，我还用[]检查了convert -version
make
通常安装在find / -iname "make" 2>/dev/null中，我的是。
建议作为带有PATH变量的选项的修补程序如下所示：
/usr/bin/make
对于已经处理了一天或更多时间的人来说，这可能很容易，但是对于新手来说，这可能会很棘手。
因此请确保比较您拥有的ImageMagick的版本，并在此PATH命令中对其进行相应的更新。
也要区分大小写，在我的情况下，“ Q”不是大写字母“ Q”，而是一个小写字母。我在Magick-config的位置路径中找到了它（请参阅上面运行的命令）。
因此，我的PATH看起来像这样：PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH"
所以我运行了PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.9.7/bin-q16:$PATH"以清除所有缓存，然后在终端和瞧中运行了正确的PATH命令。如果有人想添加任何内容或根据我的逻辑纠正我，请这样做，我们欢迎您提出所有意见。
