无法在Ubuntu 13.04上安装rmagick gem

Question

当我尝试安装rmagic时:

gem install rmagic

它给出了错误:

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:

我试图搜索问题,发现我缺少libmagickwand-dev.我尝试安装它:

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:

sudo apt-get install libglib2.0-dev

它给出了错误:

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libglib2.0-0:

sudo apt-get install libglib2.0-0

它给:

libglib2.0-0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

如果我用以下命令安装libglib2.0-bin:

sudo apt-get install libglib2.0-bin

它给:

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:

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.

这可能有什么问题？

我正在使用Ubuntu 13.04,rbenv,ruby 2.0.0,如果这很重要的话.

Answer 1

试试这个

首先安装imagemagick

sudo apt-get install imagemagick

然后

sudo apt-get install libmagickwand-dev

Answer 2

解决方案是在可以找到这些库的位置添加ppa.

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
