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).
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）。
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).
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）。
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 3.3first.
如果您确实需要编译自己的 PyQt5 版本，步骤（如您所见）在此处，但假设您已安装 python 和编译器并在您的路径中。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。

First try this in your Windows cmd window:
首先在您的 Windows cmd 窗口中尝试此操作：
pip3 install pyqt5
If that is successful, it will look something like this:
如果成功，它将看起来像这样：

PyQt5 .exe installers for Windows
How to find the installer that's right for you?
如何找到适合您的安装程序？
First, determine what version of Python you have and whether you have 32-bit or 64-bit Python. Next, open one of the directories. I'm on Python 3.5 64-bit so I'm looking for a .exe with those specs. When you open a directory on SourceForge, you will see some directories with ONLY .zipor .tar.gz. That's not what you're looking for. A good indication of which directory you should click is given by the "Downloads/Week" column. I'll open the PyQt-5.6directory in my case.
首先，确定您使用的是哪个版本的 Python，以及您使用的是 32 位还是 64 位 Python。接下来，打开其中一个目录。我使用的是 Python 3.5 64 位，所以我正在寻找具有这些规格的 .exe。当你在 SourceForge 上打开一个目录时，你会看到一些只有.zip或.tar.gz 的目录。那不是你要找的。“下载/周”列很好地表明了您应该单击哪个目录。在我的例子中，我将打开PyQt-5.6目录。
Here we notice some .exe files:
这里我们注意到一些 .exe 文件：
PyQt-5.6
|_PyQt5-5.6-gpl-Py3.5-Qt5.6.0-x32-2.exe
|_PyQt5-5.6-gpl-Py3.5-Qt5.6.0-x64-2.exe
|_PyQt5_gpl-5.6.zip
|_PyQt5_gpl-5.6.tar.gz
I know these are Python 3.5 by Py3.5in the file name. I am also looking for the 64-bit version so I'll download PyQt5-5.6-gpl-Py3.5-Qt5.6.0-x64-2.exe. Final answer!
我知道这些是Py3.5文件名中的 Python 3.5 。我也在寻找 64 位版本，所以我会下载PyQt5-5.6-gpl-Py3.5-Qt5.6.0-x64-2.exe. 最终答案！
Note: if you try to install a version that's not compatible with your system, a dialog box will appear immediately after running the .exe. That's an indication that you've chosen the wrong one. I'm not trying to sound like a dbag... I did that several times!
注意：如果您尝试安装与您的系统不兼容的版本，运行 .exe 后会立即出现一个对话框。这表明你选错了。我不是想听起来像个包包……我做了好几次！
To test a successful install, in your Python interpreter, try to import:

One of the most (probably the most) easiest way to install site-packages like PyQt5 is installing one of the versions of Anaconda. You can just install many of site-packages by installing it. List of avaliable site-packages with Anaconda versions can be checked here.
安装像 PyQt5 这样的站点包的最（可能是最）最简单的方法之一是安装 Anaconda 的一个版本。您可以通过安装来安装许多站点包。可以在此处检查具有 Anaconda 版本的可用站点包列表。
- Dowload Anaconda3or Anaconda2
- Install it.
- Add PyQt5's path inside Anaconda installation to your System Environment Variables.
- 下载 Anaconda3或 Anaconda2
- 安装它。
- 将 Anaconda 安装中 PyQt5 的路径添加到您的系统环境变量中。
For example:
例如：
PATH: ....; C:\Anaconda3\Lib\site-packages\PyQt5; ...
- It is ready to use.
- 它可以使用了。

I'm new to both Python and PyQt5. I tried to use pip, but I was having problems with it using a Windows machine. If you have a version of Python 3.4 or above, pip is installed and ready to use like so:
我是 Python 和 PyQt5 的新手。我尝试使用 pip，但我在使用 Windows 机器时遇到了问题。如果您有 Python 3.4 或更高版本，pip 已安装并可以使用，如下所示：
python -m pip install pyqt5
That's of course assuming that the path for Python executable is in your PATH environment variable. Otherwise include the full path to Python executable (you can type where pythonto the Command Window to find it) like:
这当然是假设 Python 可执行文件的路径在您的 PATH 环境变量中。否则，包括 Python 可执行文件的完整路径（您可以where python在命令行窗口中键入以找到它），例如：
C:\users\userName\AppData\Local\Programs\Python\Python34\python.exe -m pip install pyqt5

This will install the Python wheelfor your platform and your version of Python(assuming both are supported).
这将安装了Python的车轮所用平台的Python版本（假设两者都支持）。
(The wheel will be automatically downloaded from the Python Package Index.)
（轮子将自动从Python Package Index下载。）
The PyQt5 wheel includes the necessary parts of the LGPL version of Qt. There is no need to install Qt yourself.
PyQt5 轮包括 Qt LGPL 版本的必要部分。无需自己安装 Qt。
(The required sipis packaged as a separate wheel and will be downloaded and installed automatically.)
（需要sip打包成单独的轮子，会自动下载安装。）
Note:
注意：
If you get an error message saying something as
如果您收到一条错误消息，内容如下
No downloads could be found that satisfy the requirement
No downloads could be found that satisfy the requirement
then you are probably using an unsupported versionof Python.
那么您可能正在使用不受支持的 Python版本。
