当我尝试运行 rails server 时出现上述错误

Answer 1

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

brew uninstall --force imagemagick

注意:由于安装了多个旧版本，我不得不使用 --force。如果您担心 --force 选项，您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
