解决方案

安装 PyQt 的最简单方法是使用安装程序(链接在您的答案中，第 5 步).如果您安装 python 3.3，安装程序会自动将所有 PyQt5 附加组件添加到该 python 安装中.你不需要做任何编译(没有:nmake、nmake install、python configure).

如果您需要自定义安装，则所有构建选项都可用(例如，使用不同版本的 Python，其中没有 Riverbank 计算提供的安装程序).

如果您确实需要编译自己的 PyQt5 版本，步骤(如您所见)是这里，但假设您安装了 python 和编译器，并且在您的路径中.安装的和在您的路径中似乎是您遇到麻烦的地方.我建议使用安装程序版本，但您需要先安装 python 3.3.

When I try installing the PyQt5 on Windows using the command

python configure.py

I get this error:

Error: Make sure you have a working Qt qmake on your PATH.

I got the pyQt5 from PyQt5 Download.

How can I install PyQt5?

Update:

I installed Qt 5.0.2 for Windows 64-bit (VS 2012, 500 MB) from the Qt Download page and now I have this error:

Querying qmake about your Qt installation...
Determining the details of your Qt installation...
Error: Failed to determine the detail of your Qt installation. Try again using
the --verbose flag to see more detail about the problem.

And when I execute the command python configure.py --verbose:

I added C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin (contains nmake.exe) to PATH and I got this error:

解决方案

The easiest way to install PyQt is to just use the installer (Link in your answer, step #5). If you install python 3.3, the installer will add all of the PyQt5 extras to that python installation automatically. You won't need to do any compiling (none of: nmake, nmake install, python configure).

All of the build options are available for if you need a custom install (for instance, using a different version of python, where there isn't an installer provided by riverbank computing).

If you do need to compile your own version of PyQt5, the steps (as you have found) are here, but assume you have python and a compiler installed and in your path. The installed and in your path have been where you have been running into trouble it seems. I'd recommend using the installer version, but you need to install python 3.3 first.
