我试图搜索问题，发现我缺少libmagickwand-dev。我尝试安装它：
I tried to search for problem and found that I am missing libmagickwand-dev. I tried to install it with:
sudo apt-get install libmagickwand-dev
但它会引发错误：
The following packages have unmet dependencies:
libmagickwand-dev : Depends: libmagickcore-dev (= 8:6.7.7.10-5ubuntu2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
如果我尝试安装它：
sudo apt-get install libmagickcore-dev
它给出了错误：
The following packages have unmet dependencies:
libmagickcore-dev : Depends: librsvg2-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
如果我尝试安装它：
sudo apt-get install librsvg2-dev
它给出了错误：
The following packages have unmet dependencies:
librsvg2-dev : Depends: libglib2.0-dev (>= 2.24.0) but it is not going to be installed
Depends: libgdk-pixbuf2.0-dev (>= 2.23.5-2) but it is not going to be installed
Depends: libcairo2-dev (>= 1.2.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
如果我尝试使用以下命令安装libglib2.0-dev：
If I try to install libglib2.0-dev with:
sudo apt-get install libglib2.0-dev
它给出错误：
The following packages have unmet dependencies:
libglib2.0-dev : Depends: libglib2.0-0 (= 2.36.0-1ubuntu1) but 2.36.0-1ubuntu2 is to be installed
Depends: libglib2.0-bin (= 2.36.0-1ubuntu1)
E: Unable to correct problems, you have held broken packages.
如果我安装了libglib2.0-0：
If I install libglib2.0-0 with:
sudo apt-get install libglib2.0-0
it gives:
libglib2.0-0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
如果我安装了libglib2.0-bin：
If I install libglib2.0-bin with:
sudo apt-get install libglib2.0-bin
它给出：
Reading package lists... Done
Building dependency tree
Reading state information... Done
libglib2.0-bin is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
这两个库已经安装但是再次发布：
Those 2 libs are installed but issuing again:
sudo apt-get install libglib2.0-dev
它给出了同样的错误：
The following packages have unmet dependencies:
libglib2.0-dev : Depends: libglib2.0-0 (= 2.36.0-1ubuntu1) but 2.36.0-1ubuntu2 is to be installed
Depends: libglib2.0-bin (= 2.36.0-1ubuntu1)
E: Unable to correct problems, you have held broken packages.
这里有什么问题？
我正在使用Ubuntu 13.04，rbenv，ruby 2.0.0，如果这很重要。
I am using Ubuntu 13.04, rbenv, ruby 2.0.0, if that matters.
推荐答案
解决方案是在这些库中添加ppa可以找到。
Solution is to add ppa where those libs could be found.
添加PPA：
sudo add-apt-repository ppa:ricotz/testing
然后更新包列表：
sudo apt-get update
最后安装它：
sudo apt-get install libmagickwand-dev
