brew install freetype
返回:

看来我的系统上安装了 freetype。那么发生了什么？令人失望的是，像 matplotlib 这样重要的 Python 包没有安装。
如有任何帮助，我们将不胜感激。
最佳答案
由于您使用的是 Enthought，因此安装 matplotlib 等内容的推荐方法是安装 Canopy Express ，它是 Enthought 发行版的免费附加组件，还允许您访问约 100 个可以轻松安装到 Enthought 中的软件包。
您尝试使用 brew 执行的操作不适用于开箱即用的 Enthought，并且需要您设置正确的环境变量和build设置，因为整个系统不支持了解 brew 的存在。
