You need to install SIP first, which is not just running configure.py:
您需要先安装 SIP，这不仅仅是运行configure.py：
>>> cd ~/Downloads/sip-4.17
>>> python configure.py
>>> make
>>> make install
Then you can install PyQt5:
然后你可以安装PyQt5：
>>> cd ~/Downloads/PyQt-gpl-5.5.1
>>> python configure.py --qmake /Users/name/Qt/5.5/clang_64/bin/qmake
>>> make
>>> make install

Meanwhile I have the ultimate way to install PyQt5 on macOS. Don't use Homebrew. It is great for installing Qt5, but for PyQt5 the best way to install it is using
同时我有在 macOS 上安装 PyQt5 的终极方法。不要使用Homebrew。它非常适合安装 Qt5，但对于 PyQt5，安装它的最佳方法是使用
python3 -m pip install PyQt5
This works very quickly and uses universal Python Wheels:
这工作得非常快，并使用通用的 Python Wheels：

You see: Such a wheel is re-used for CPython 3.5, 3.6 and 3.7.
您会看到：CPython 3.5、3.6 和 3.7 重新使用了这样的轮子。
Old remark, but see below: PySide2 is not as far, but we will build similar wheels when we have the first version ready.
旧评论，但请参见下文：PySide2 还没有那么远，但是当我们准备好第一个版本时，我们将构建类似的轮子。
Added on 2017/09/25: You can of course also use
于 2017/09/25 添加：您当然也可以使用
pip3 install PyQt5
But at that time my pip/pip2/pip3 was a bit messy linked, so the first solution is rock solid and avoids confusion.
但当时我的 pip/pip2/pip3 链接有点乱，所以第一个解决方案是坚如磐石的，避免了混乱。
Also right is that you don't always get the lastest version of PyQt5 this way. But for getting started, the priority is to get results quickly and not the bleeding edge.
同样正确的是，您并不总是以这种方式获得最新版本的 PyQt5。但是对于入门而言，首要任务是快速获得结果而不是前沿。
Update: PySide2 now officially has wheels, to:
更新：PySide2 现在正式有了轮子，可以：
$ python3 -m pip install PySide2

Qt is set of cross-platform C++ libraries that implement high-level APIs for accessing many aspects of modern desktop and mobile systems. These include location and positioning services, multimedia, NFC and Bluetooth connectivity, a Chromium based web browser, as well as traditional UI development.
Qt 是一组跨平台的 C++ 库，它们实现了高级 API，用于访问现代桌面和移动系统的许多方面。其中包括位置和定位服务、多媒体、NFC 和蓝牙连接、基于 Chromium 的网络浏览器以及传统的 UI 开发。
PyQt5 is a comprehensive set of Python bindings for Qt v5. It is implemented as more than 35 extension modules and enables Python to be used as an alternative application development language to C++ on all supported platforms including iOS and Android.
PyQt5 是 Qt v5 的一套全面的 Python 绑定。它以超过 35 个扩展模块的形式实现，使 Python 能够在所有支持的平台（包括 iOS 和 Android）上用作 C++ 的替代应用程序开发语言。
PyQt5 may also be embedded in C++ based applications to allow users of those applications to configure or enhance the functionality of those applications.
PyQt5 也可以嵌入基于 C++ 的应用程序中，以允许这些应用程序的用户配置或增强这些应用程序的功能。

Qt has a Mac .dmg installer with all the components. I uninstalled my pip version first, and installed my Qt into the standard location - I tried putting into /opt/Qt as suggested by another post, but it failed due to changes to MacOS rights in Mojave. There is an expansion triangle next to the Qt item which allows for installing Designer separately from the Qt engine and the 2D/3D development and platform-specific tools.
Qt 有一个包含所有组件的 Mac .dmg 安装程序。我先卸载了 pip 版本，然后将 Qt 安装到标准位置 - 我尝试按照另一篇文章的建议放入 /opt/Qt，但由于 Mojave 中 MacOS 权限的更改而失败。Qt 项旁边有一个扩展三角形，它允许将 Designer 与 Qt 引擎以及 2D/3D 开发和特定于平台的工具分开安装。
