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   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 python to the Command Window to find it  like   C  users userName AppData Local Programs Python Python34 python exe -m pip install pyqt5

First try this in your Windows cmd window   pip3 install pyqt5   If that is successful  it will look something like this   C  Windows System32 gt pip3 install pyqt5 Collecting pyqt5   Downloading PyQt5-5 9-5 9 1-cp35 cp36 cp37-none-win amd64 whl  77 2MB      100                                     77 2MB 13kB s Collecting sip lt 4 20  gt  4 19 3  from pyqt5    Downloading sip-4 19 3-cp35-none-win amd64 whl  49kB      100                                     51kB 984kB s Installing collected packages  sip  pyqt5 Successfully installed pyqt5-5 9 sip-4 19 3   If that did not work  you might try this link from SourceForge   PyQt5  exe installers for Windows  How to find the installer that s right for you   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  zip or  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 6 directory in my case   Here we notice some  exe files   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 5 in 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   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   To test a successful install  in your Python interpreter  try to import   from PyQt5 import QtCore  QtGui  QtWidgets

If you re using Windows 10  if you use      py -m pip install pyqt5   in the command prompt it should download fine  Depending on either the version of Python or Windows sometimes python -m pip install pyqt5 isn t accepted  so you have to use py instead  pip is a good way to download a lot of stuff  so I d recommend that

To install the GPL version of PyQt5  run  see PyQt5 Project    pip3 install pyqt5   This will install the Python wheel for your platform and your version of Python  assuming both are supported      The wheel will be automatically downloaded from the Python Package Index    The PyQt5 wheel includes the necessary parts of the LGPL version of Qt  There is no need to install Qt yourself    The required sip is packaged as a separate wheel and will be downloaded and installed automatically      Note   If you get an error message saying something as   No downloads could be found that satisfy the requirement     then you are probably using an unsupported version of Python

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      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    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 3 first
