无法在debian 7.6上安装rmagick (包冲突)

Question

我正在尝试在Debian 7.6 (Wheezy)上安装redmine 2.5.4。我遇到了一个问题，为什么我尝试安装rmagick gem。

我尝试了apt-get install libmagickwand-dev libmysqlclient-dev和apt-get install libmagick++-dev，但是我无法安装。事实上，在以下情况下，已经显示出冲突：

maxime@ns504687:/opt/redmine$ sudo aptitude why-not libmagick++-dev
i   imagemagick                         Suggests  html2ps
p   html2ps                             Depends   perlmagick
p   graphicsmagick-libmagick-dev-compat Provides  perlmagick
p   graphicsmagick-libmagick-dev-compat Conflicts libmagick++-dev

下面是apt-get install libmagickwand-dev libmysqlclient-dev的结果

maxime@ns504687:/opt/redmine$ sudo apt-get install libmagickwand-dev libmysqlclient-dev

libmysqlclient-dev is already the newest version.
libmysqlclient-dev set to manually installed.

我尝试了很多在网上找到的解决方案，但都没有成功。

你能帮帮我吗？

因此，至少这里是来自Redmine站点https://www.redmine.org/projects/redmine/wiki/RedmineInstall的教程

只需运行该命令

bundle install --without development test

然后

bundle install --without development test rmagick
