像许多其他人一样，我在运行捆绑安装时在 Ubuntu 上安装 rmagick 时遇到了麻烦。
我在捆绑安装命令中收到此错误：
Installing rmagick (2.13.1)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

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:

--with-opt-include
--without-opt-include=${opt-dir}/include

Gem files will remain installed in /home/selfsale/.bundler/tmp/2908/gems/rmagick-2.13.1 for inspection.
Results logged to /home/selfsale/.bundler/tmp/2908/gems/rmagick-2.13.1/ext/RMagick/gem_make.out
An error occurred while installing rmagick (2.13.1), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.
然后我做了一些搜索，发现了一些添加缺失库的建议：
sudo apt-get 安装 libmagick9-dev：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libmagick9-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
graphicsmagick-libmagick-dev-compat
E: Package 'libmagick9-dev' has no installation candidate
sudo apt-get install graphicsmagick-libmagick-dev-compat：

似乎任何安装正确软件包的尝试都会出现此问题。
我刚刚看到一篇关于从源代码安装 imagemagick 的帖子，所以我要尝试一下，但如果有人有更好的想法，我很想听听他们的意见。
谢谢
