Command python setup.py egg_info failed with error code 1 in /tmp/pip-build/matplotlib

同时，
brew install freetype
返回：
Warning: freetype-2.6_1 already installed
所以看起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 这样关键的 Python 包没有安装。
任何帮助将不胜感激。
【问题讨论】：
-
另一方面，
ls -l /usr/include/freetype2/ft2build.h找不到。 -
您是否正在尝试将 matplotlib 安装到系统 Python 中？这似乎不是您将其安装到
brew管理的 Python 中。 -
我正在安装到 Enthought（当前设置为默认 Python 解释器）。
-
由于您使用的是 Enthought，推荐安装
matplotlib之类的方法是安装 Canopy Express。这是 Enthought 发行版的免费附加组件，它还允许您访问大约 100 个可以轻松安装到 Enthought 的软件包。您尝试对brew执行的操作不适用于 Enthought 开箱即用，并且需要您设置正确的环境变量和构建设置，因为整个系统不了解brew的存在. -
@birryree 有效。请随意发布它作为答案，我会选择它！
