What should I do?

我应该做什么?

This is what I've done is this:

我所做的是:

Installed Python 3.3 and added to PATH
安装Python 3.3并添加到PATH中
Installed PyQt5-5.2-gpl-Py3.3-Qt5.2.0-x64.exe
安装pyqt5 - 5.2 - gpl - py3.3 - qt5.2.0 x64.exe

And I don't know how to use PyQt in pycharm.
can you provide more information?

AFAIK, you cannot install PyQt4/PyQt5 from PyPI. You would have to install it separately.

AFAIK，无法从PyPI安装PyQt4/PyQt5。你必须分开安装。

If you see this link, 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 here and install it.

如果您看到这个链接，您可以看到PyQt5(同样是PyQt4)在PyPI上没有列出的包。因此，您需要从这里单独下载安装程序并安装它。

That is what the

DistributionNotFound: No distributions at all found for PyQt5

分布没有发现:在PyQt5中没有发现分布。
