在Rails应用程序上现有Ruby的Bundler错误

Question

我的开发环境，在云（cloud9）中。Ruby版本-2.1.5Rails版本-4.2.1

我现有的应用Ruby版本是2.1.1，Rails 4。

当我被给予捆绑包时，安装它显示错误

如何解决此问题？

Answer 1

我会看这一行：

checking for outdated ImageMagick version (<= 6.4.9)... *** extconf.rb failed ***

和

extconf.rb:79:in ``': No such file or directory - convert (Errno::ENOENT)

它试图更新失败的图像魔术。ImageMagic是否正确安装了，您是否使用与Cloud9上安装的版本相比需要另一个版本的GEM？

在他们的网站上，建议：

sudo apt-get install imagemagick

我建议在捆绑之前更新图像数字二进制。

希望这会有所帮助。

Answer 2

您还需要安装开发库。我现在无法访问Ubunt机器，但是运行此操作应该扔出正确的软件包。

APT-CACHE搜索ImageMagick |grep dev

在Guess

上寻找类似ImageMagick-Dev的东西

在Fedora上可以安装包装如下

DNF安装ImageMagick-Devel
