Answer 1

这是因为该文件包含的是configure.py而不是setup.py。通过将--qmake选项传递给configure.py，configure.py生成一个make文件，您可以使用该文件根据您选择的qt库构建pyqt，它也有不同的选项。我建议向pip维护者提交一个bug。

Answer 2

如果你使用的是Mac，你可以使用homebrew

brew install pyqt

Answer 3

或者，您可以使用ActivePython的二进制包管理器进行install PyQt4。

$ pypm install pyqt4
The following packages will be installed into "~/.local" (2.7):
 pyqt4-4.8.3.0
Hit: [pypm-free.activestate.com] pyqt4 4.8.3.0
Installing pyqt4-4.8.3.0
$

只要你已经有了PyPM，就不需要编译了。
