我尝试使用 pip install matplotlib
和 git clone
然后 python setup.py install
,如安装常见问题所述,在Mac OS 10.7上安装matplotlib。但是我得到了相同的错误:

看起来我在系统中缺少某些软件包?还有其他更好的安装matplotlib的方式吗?
谢谢!
更新:通过谷歌和搜索SO,我发现我可能缺少freetype2包,但是,如果我尝试通过Homebrew安装它,我会收到警告消息:
[me @ my mac]$ brew search freetype
Apple distributes freetype with OS X, you can find it in /usr/X11/lib.
However not all build scripts look here, so you may need to call ENV.x11
in your formula's install function.
brew install freetype
然后pip install matplotlib
解决了我的问题。 - hobsbrew install libpng
才能成功地pip install matplotlib
。感谢Javier列出这些软件包。 - Bryan P
