Answer 1

我能够修复此错误,因此如果他们遇到同样的问题,这应该适用于其他任何人.

以下是修复的步骤:

brew uninstall imagemagick
gem uninstall rmagick
sudo gem install json # (not sure this step is needed)
sudo apt-get install libmagick9-dev
bundle install

然后它完美无缺.现在我可以启动rails服务器,我不会收到任何错误.希望这有助于某人!

Answer 2

您只需使用当前的 imagemagick 重新安装 rmagick

gem install rmagick

在其他问题中，我发现以下方法通过使用解决了问题，

gem pristine rmagick
