我曾尝试卸载/安装 libtiff、imagemagick，但无法正常工作

$ brew uninstall libtiff
$ brew install imagemagick
$ brew uninstall imagemagick
$ brew install imagemagick

知道我的安装有什么问题吗？提前致谢，

我也遇到了同样的问题，只是设法解决了它。

brew install libtiff
brew install imagemagick --with-libtiff

我尝试了多次卸载和重新安装 imagemagick 和 libtiff 的组合，但每次都得到相同的结果。我希望 brew 会神奇地拾取 libtiff 并将其链接。

我最终通过查看命令的输出找到了 with-libtiff 选项

1
brew info imagemagick

在 2013 年 1 月 30 日之前，该选项被称为 --use-tiff。
