我该怎么办？
This is what I've done is this:
这就是我所做的：
- Installed Python 3.3 and added to PATH
- Installed
PyQt5-5.2-gpl-Py3.3-Qt5.2.0-x64.exe
- 安装 Python 3.3 并添加到 PATH
- 已安装
PyQt5-5.2-gpl-Py3.3-Qt5.2.0-x64.exe
And I don't know how to use PyQtin pycharm.

AFAIK, you cannot install PyQt4/PyQt5 from PyPI. You would have to install it separately.
AFAIK，你不能从 PyPI 安装 PyQt4/PyQt5。您必须单独安装它。
If you see thislink, you can see that there are no listed packages for PyQt5 (likewise for PyQt4) on PyPI. So, you would need to download the installer separately from hereand install it.
如果你看到这个链接，你可以看到 PyPI 上没有列出 PyQt5（PyQt4 也是如此）的包。因此，您需要从此处单独下载安装程序并进行安装。

FYI, installing QtPy5 with pip works in 3.6.5. According to https://www.riverbankcomputing.com/software/sip/downloadeven 3.5 and later.
仅供参考，使用 pip 安装 QtPy5 可以在 3.6.5 中运行。根据https://www.riverbankcomputing.com/software/sip/download甚至 3.5 及更高版本。
