Question

当尝试安装fileutils gem时，我得到以下输出：

No package 'MagickCore' found
Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
to the PKG_CONFIG_PATH environment variable

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

看起来rmagick存在一些问题，imagemagick已正确安装，并且在尝试安装rmagick gem时我收到错误的包丢失：libmagickwand-dev

当我尝试安装此软件包时，出现以下错误：

The following packages have unmet dependencies:
 libmagickwand-dev : Depends: libmagickcore-dev (= 8:6.6.9.7-5ubuntu3.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Answer 1

正在运行sudo apt-get install libmagickwand-dev解决了我的问题。

Answer 2

安装这两个软件包

sudo apt-get install libmagickwand-dev
sudo apt-get install imagemagick

在你的Gemfile中添加这些行

# To perform file operations
gem 'rmagick'
gem 'fileutils', '~> 0.7'

然后你可以通过运行

来安装宝石

bundle install

作为命令的输出，您应该看到类似于此的内容......

...
Installing rmagick 2.13.4
Installing fileutils 0.7
....
Your bundle is complete!

Answer 3

从我所看到的宝石已被移除，检查here，没有可用的来源，所以如果可以，你可以选择另一个宝石，如metadata

无法在ubuntu 14.04上安装fileutils Rubygem
