使用自制程序安装的依赖项

brew install freetype
brew install libpng

通过克隆github repo安装matplotlib和numpy：

sudo python setup.py build
sudo python setup.py install

非常感谢任何解决此问题的帮助。

Answer 1

该文件中存在语法错误。我猜你在使用开发资源？那个rb不应该在正则表达式之前（在Python 2.x中它应该是r，在Python 3.x中可能是b。

更新：是的。这是错误的提交：

Answer 2

三位一体：

sudo pip install numpy
sudo pip install matplotlib
sudo pip install scipy

如果您使用master编译它，请运行sudo brew update然后：

sudo brew install freetype
sudo brew install libpng

然后构建并安装：

sudo python setup.py build
sudo python setup.py install

Answer 3

应该是br。这将在matplotlib master中修复。
