【问题描述】：
尝试在我的 Mac (Yosemite 10.10.5) 上安装 imagemagick（将与 PaperClip gem 一起使用）引发错误“libtool”会发生什么？
$ brew update
$ brew install imagemagick

-
您是否下载、安装和更新了 Xcode 命令行工具？
-
我猜最近有一个 XCode 上传...我可能需要更新 CL 工具...检查谢谢...
-
就是这样 .. OS X 已更新，但我忘记更新 CL 工具...感谢您让我上轨道...
-
即使在 OS X CL 更新之后，也不会出现与 brew install imagemagick ownloading ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.xz curl 相同的错误消息：(4) 在此 libcurl 中未找到内置的请求功能、协议或选项构建时的决定。正在尝试镜像... ==> 正在下载 ftp.gnu.org/gnu/libtool/libtool-2.4.6.tar.xz curl：(4) 由于构建时间决定，在此 libcurl 中未找到内置的请求功能、协议或选项。

我在 cactuslab.com/imagemagick 找到了一个包，它将 imagemagick 安装到 /opt 中，然后将 bin 添加到 $PATH... 现在正在运行
