Answer 1

这是因为该文件有configure.py而不是setup.py。 configure.py生成一个make文件，用于通过将--qmake选项传递给configure.py来针对您选择的qt库构建pyqt，它也有不同的选项。我建议用pip维护者填写一个bug。

如果你在Mac上，你可以使用homebrew：

brew install pyqt

Answer 3

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

$ 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PyPM，就不需要编译。

Answer 4

您可以在下载..google所需的版本后，将pip安装下载的pyqt版本的目录
