python - PyQt5的PyQt5.sip文件不是由SIP库生成的

Question

我正在使用 Visual Studio 2017 在 Windows 10 上构建 SIP 4.19.12 和 PyQt 5.11.2。我计划为 Python x86 2.7.15 执行此操作。我下载了上面的版本并解压了它们，用 pip 安装了 enum34，用

配置了 SIP

python configure.py --sip-module PyQt5.sip --no-tools

这是适用于 win32 上的 Python 2.7.15 的 SIP 4.19.12。

The PyQt5.sip module will be installed in

C:\Users\FiFo\AppData\Local\Programs\Python\Python27\Lib\site-packages\PyQt5.

The sip.pyi stub file will be installed in

C:\Users\FiFo\AppData\Local\Programs\Python\Python27\Lib\site-packages\PyQt5.

The default directory to install .sip files in is

C:\Users\FiFo\AppData\Local\Programs\Python\Python27\sip. Creating

sipconfig.py... Creating top level Makefile... Creating sip code

generator Makefile... Creating sip module Makefile...

设置 x86 构建环境

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" x86

接着是nmake:

    cd siplib

然后使用 nmake install 安装软件包:

    cd siplib
    "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.15.26726\bin\HostX86\x86\nmake.exe"

install

但我无法在任何地方找到 PyQt5.sip 文件。构建 PyQt 提供:

Answer 1

这是稳定版的一个错误。作者建议下载有效的最新快照。另一种解决方案是:

“在包含 sip.pyd 的同一目录中创建一个空的 __init__.py 文件。”

之后我配置了:

python configure.py --qmake d:\qt5_32\bin\qmake.exe --static --sip-incdir ..\sip-4.19.13.dev1809111822\siplib --sip d:\opencv\sip-4.19.13.dev1809111822\sipgen\sip.exe --confirm-license
