当我尝试运行rails服务器时出现上述错误

Answer 1

接受的答案已过期。我在Mac OSX（El Capitan）和ImageMagick（6.9.4）上遇到了这个问题。我通过恢复到旧版本的ImageMagick并重新安装rmagick来解决它，如下所示：

brew uninstall --force imagemagick

注意：我必须使用--force，因为安装了多个旧版本。如果您担心--force选项，也可以多次运行该命令。

brew tap homebrew/versions
brew install https://raw.githubusercontent.com/Homebrew/homebrew-versions/master/imagemagick-ruby186.rb
gem uninstall rmagick
gem install rmagick -v 2.15.0

Answer 2

当我部署rails应用程序时，我遇到了同样的问题，这是我必须要解决的问题。

首先确保从项目中删除imageMagick，在终端中执行以下命令

brew uninstall imagemagick

如果您收到错误，我们会使用。

brew uninstall -f imagemagick

然后安装版本2.14.0，这是我找到的最后一个工作版。

gem install rmagick -v 2.14.0

确保在使用bundle update之前将版本号添加到Gemfile中，如果遇到错误，请删除Gemfile.lock，这样bundle就可以重置任何奇怪的依赖项。

gem 'rmagick', '2.14.0'

如果我是对的，它应该再次运作。

我想，使用RMagick安装的ImageMagick版本不支持此link
