You can t use pip  You have to download from the Riverbank website and run the installer for your version of python  If there is no install for your version  you will have to install Python for one of the available installers  or build from source  which is rather involved   Other answers and comments have the links

Here are Windows wheel packages built by Chris Golke - Python Windows Binary packages - PyQt  In the filenames cp27 means C-python version 2 7  cp35 means python 3 5  etc   Since Qt is a more complicated system with a compiled C   codebase underlying the python interface it provides you  it can be more complex to build than just a pure python code package  which means it can be hard to install it from source   Make sure you grab the correct Windows wheel file  python version  32 64 bit   and then use pip to install it - e g   C  path where wheel is  gt  pip install PyQt4-4 11 4-cp35-none-win amd64 whl   Should properly install if you are running an x64 build of Python 3 5

I am using PyCharm  and was able to install PyQt5   PyQt4  as well as PyQt4Enhanced and windows whl both failed to install  I m guessing that s because Qt4 is no longer supported

Try this for PyQt5   pip install PyQt5   Use the operating system on this link for PyQt4   Or download the supported wheel for your platform on this link   Else use this link for the windows executable installer  Hopefully this helps you to install either PyQt4 or PyQt5

Earlier PyQt  exe installers were available directly from the website download page  Now with the release of PyQt4 12   installers have been deprecated  You can make the libraries work somehow by compiling them but that would mean going to great lengths of trouble   Otherwise you can use the previous distributions to solve your purpose  The  exe windows installers can be downloaded from       https   sourceforge net projects pyqt files PyQt4 PyQt-4 11 4

If you install PyQt4 on Windows  files wind up here by default      C  Python27 Lib site-packages PyQt4      but it also leaves a file here      C  Python27 Lib site-packages sip pyd   If you copy the both the sip pyd and PyQt4 folder into your virtualenv things will work fine   For example   mkdir c  code cd c  code virtualenv BACKUP cd c  code BACKUP scripts activate   Then with windows explorer copy from C  Python27 Lib site-packages the file  sip pyd  and folder  PyQt4  mentioned above to C  code BACKUP Lib site-packages   Then back at CLI   cd                      c  code BACKUP  python backup py   The problem with trying to launch a script which calls PyQt4 from within virtualenv is that the virtualenv does not have PyQt4 installed and it doesn t know how to reference the default installation described above  But follow these steps to copy PyQt4 into your virtualenv and things should work great
