PyQt5 5.8.2 从 Windows 10 上的源代码构建

Question

我正在使用 Python 3.6 与 Qt 5.8 的 qmake 和 VS2017 的 nmake 来尝试从源代码构建 PyQt5。

但是我在

的第一步遇到了如下错误

python configure.py --verbose :

C:\Qt.8\msvc2015_64\include\QtCore/qalgorithms.h(593): error C3615: constexpr function 'QAlgorithmsPrivate::qt_builtin_ctz' cannot result in a constant expression

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio17\Community\VC\Tools\MSVC.10.25017\bin\HostX64\x64\cl.EXE"' : return code '0x2'
Stop.

注意：我后来使用 pip install PyQt5 成功安装了 PyQt5，它工作正常。但是我无法弄清楚为什么会出现错误，我仍然想解决它以避免将来出现同样的问题。
