python - 在 Mac OS X 10.8.3 上导入 pylab 的问题

Question

导入pylab时出现如下错误:

SyntaxError: invalid syntax

使用自制软件安装依赖

brew install freetype
brew install libpng

通过克隆 github 存储库并执行以下操作来安装 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？ rb 不应该出现在正则表达式之前(在 Python 2.x 中应该是 r，在 Python 3.x 中可能是 b ).

更新:是的。这是错误的提交:
