（编辑：解决方案见底部）我正在制作一个 Ruby On Rails 项目并尝试安装 RMagick gem。使用 OS X 10.6、Ruby 版本 2.0.0p247、Rails 4.0.0、RVM 1.22.12。

当我运行捆绑安装时，我收到以下错误：

...
Installing rmagick (2.13.2) 
Errno::EACCES: Permission denied - /Users/jasonpather/.rvm/gems/ruby-2.0.0-p247/g
ems/rmagick-2.13.2/build_tarball.rake
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.

那么我尝试这个建议：

Jason-Pathers-MacBook-Pro:BuyABrick jasonpather$ gem install rmagick -v '2.13.2'
ERROR:  While executing gem ... (Errno::EACCES)
Permission denied - /Users/jasonpather/.rvm/gems/ruby-2.0.0-p247/gems/rmagick
-2.13.2/build_tarball.rake

所以然后我尝试sudo：

Jason-Pathers-MacBook-Pro:BuyABrick jasonpather$ sudo gem install rmagick -v '2.1
3.2'

我将非常感谢任何帮助。我在这个网站上看过类似的问题，但没有任何建议有帮助。在安装 RMagick 之前是否需要安装其他软件包？

编辑：解决方案

我只是使用自制软件安装 imagemagick brew install imagemagick，sudo gem install rmagick现在bundle install运行良好！

您需要安装 Image Magick（checking for Magick-config... no从您的日志中建议）。

最简单的方法（因为你在 Mac 上）是使用Homebrew。安装 Homebrew（按照它在安装过程中给你的任何说明进行操作——它们并不多），然后运行：

brew install imagemagick

然后bundle install再次运行。
