无法在OS X 10.10.5 Yosemite with Python 3.6中安装PyQt4

Question

今天我尝试安装需要vtk的mayavi。我终于让vtk安装并可导入，但在此过程中破坏了我的python3.4环境。不管怎样，我是时候升级到3.6了，所以这不是一个大问题，但是现在不能安装PyQt4是个大问题。

我使用Qt（5.7.1）和SIP（4.19）时只遇到了一点问题，但是我在PyQt4上遇到了障碍。我尝试过brew install pyqt，也尝试从源代码构建它。在这两种情况下，其结果是：

作为回应，我尝试了export CXXFLAGS=-std=c++11和（分别和一起）export CPPFLAGS=-std=c++11，但都没用。我还尝试将以下内容添加到qtdirs.pro文件中，但没有任何区别：

下一步是什么？

结果很容易修复。我下载并安装了qt-opensource-mac-4.8.7.dmg，这样我的/usr/bin中的qmake是针对qt4.8.7的，然后进入PyQt4_gpl_mac-4.12并键入python configure.py && make就成功地完成了。在
