导入 pylab 时出现以下错误：

使用自制软件安装依赖项

brew install freetype
brew install libpng

通过克隆 github repo 并执行以下操作安装 matplotlib 和 numpy：

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

非常感谢解决此问题的任何帮助。

该文件中存在语法错误。我猜你正在使用开发资源？那rb不应该在正则表达式之前出现（它应该r在 Python 2.x 中，也许b在 Python 3.x 中）。

更新：是的。这是错误的提交：

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

应该是br。这将暂时在 matplotlib master 中修复。
