当尝试安装fileutils gem时,我得到以下输出：

看起来像rmagick有一些问题,imagemagick安装正确,试图安装rmagick gem我收到一个包丢失的错误：libmagickwand-dev
当我尝试安装这个包我得到以下错误：
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.
运行sudo apt-get install libmagickwand-dev解决了我的问题.
