PyQt5 5.8.2 在 Windows 10 上从源代码构建

Question

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

但是，我在第一步的过程中遇到了如下错误

python configure.py --verbose：

C:\Qt\5.8\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 Studio\2017\Community\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64\cl.EXE"' : return code '0x2'
Stop.

Stop.

注意：我稍后使用pip install PyQt5 成功安装了 PyQt5，它工作正常。但我只是无法弄清楚为什么会发生错误，我仍然想解决它以避免将来出现同样的问题。

在user3419537 's suggestion 上，似乎通过 VS2015 构建和编译工作正常。
