我正在尝试在本地机器上运行一个项目.我在 Mac OS 系统上安装了 Ruby 和 Rails.它工作正常.我可以创建一个新项目并且可以正常运行它而不会出现任何错误，但是当我尝试运行现有项目时，它说我们必须bundle install.当我运行该命令时，出现以下错误:

I am trying to run one project on my local machine. I installed Ruby and Rails on my Mac OS system. It is working properly. I can create a new project and can run it properly without any error, but when I try to run the existing project it says that we have to bundle install. When I run that command I get the following error:

"An error occurred while installing rmagick (2.13.2), and Bundler cannot continue. Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling."

当我运行 gem install rmagick -v '2.13.2' 时，它给了我以下错误:

When I run gem install rmagick -v '2.13.2' it gives me the following error:

ERROR: Error installing rmagick: ERROR: Failed to build gem native extension. /usr/local/rvm/rubies/ruby-1.9.3-p392/bin/ruby extconf.rb checking for Ruby version >= 1.8.5... yes checking for gcc-4.2... yes checking for Magick-config... no Can't install RMagick 2.13.2.
