Question

在stackoverflow中浏览了许多博客以安装rmagick，但没有找到解决方案。非常感谢您的帮助。

尝试使用卸载并重新安装imagemagick。像Install rmagick

那样流动一些链接

这是输出

sudo gem install rmagick
Building native extensions.  This could take a while...

如果您已经按照链接中的说明安装了Imagemagick，则您的shell可能会缺少二进制文件的路径。您可以通过运行控制台命令进行测试：

which MagickWand-config

如果它返回路径（可能是/usr/local/bin/MagickWand-config），则您的路径可能没问题。如果返回MagickWand-config not found，您应该可以在控制台中输入export PATH=/usr/local/bin:$PATH。

如果之前的路径不正确，则在运行export命令后，可以重新运行which MagickWand-config命令以确认它在您的路径中。然后尝试再次gem install rmagick。

我能够按照您发布的链接在Mojave上安装rmagick。

如果这确实解决了您的问题，那么您还需要添加我在您的~/.bash_profile或~/.zsh_profile文件中记下的导出命令，以便该路径在每个终端窗口中都为前缀（如果尚未存在））
