我正在开发rails 4.2.7应用程序。该应用程序几天前运行良好，但是突然当我尝试安装捆绑包时，它会出现错误......"
An error occurred while installing rmagick (2.15.4), and Bundler
cannot continue.
Make sure that `gem install rmagick -v '2.15.4' --source
'https://rubygems.org/'` succeeds before bundling.'
当我运行"gem install rmagick -v '2.15.4"时，它给出错误
Building native extensions. This could take a while...

我尝试了以下命令，但没有任何效果，
sudo apt-get install graphicsmagick-libmagick-dev-compat
libmagickcore-dev libmagickwand-dev
sudo apt-get install libmagickwand-dev imagemagick
我想安装 Gem RMAGICK。
试试这个，告诉我你是否服务了
sudo apt install imagemagick libmagickcore-dev libmagickwand-dev
以下命令对我不起作用，它丢弃并中止错误。
sudo apt install imagemagick libmagickcore-dev libmagickwand-dev
什么对我有用：
sudo apt install libmagickcore-dev
分开安装它们起到了作用，不知道为什么......意识到这一点 6 小时后撞到了我的头。
