When I try installing the PyQt5 on Windows using the command
python configure.py
I get this error:
Error: Make sure you have a working Qt qmake on your PATH.
I got the pyQt5 from PyQt5 Download.
How can I install PyQt5?
Update:
I installed Qt 5.0.2 for Windows 64-bit (VS 2012, 500 MB) from the Qt Download page and now I have this error:
Querying qmake about your Qt installation... Determining the details of your Qt installation... Error: Failed to determine the detail of your Qt installation. Try again using the --verbose flag to see more detail about the problem.
And when I execute the command python configure.py --verbose:
Querying qmake about your Qt installation... Determining the details of your Qt installation... C:\Qt\Qt5.0.2\5.0.2\msvc2012_64\bin\qmake.exe -spec win32-msvc2008 -o qtdetail.m k qtdetail.pro nmake -f qtdetail.mk release 'nmake' não é reconhecido como um comando interno ou externo, um programa operável ou um arquivo em lotes.

I added C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin (contains nmake.exe) to PATH and I got this error:

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
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.
One of the most (probably the most) easiest way to install site-packages like PyQt5 is installing one of the versions of Anaconda. You can just install many of site-packages by installing it. List of avaliable site-packages with Anaconda versions can be checked here.
For example:
PATH: ....; C:\Anaconda3\Lib\site-packages\PyQt5; ...
Mainly I use the following command under the cmd
pip install pyqt5
And it works with no problem!
I found a partial solution...
Steps to install pyQt5 (with VS 2012) on Windows:
1) Install the binary file Qt 5.0.2 for Windows 64-bit (VS 2012, 500 MB) from here.
2) Get sip-4.14.7 (development snapshot) from here.
3) Extract the file and open the Developer Command Prompt for VS2012.
4) Execute these commands (in sip folder):
python configure.py
nmake
nmake install
5) Get the pyQt5 from here.
6) Extract the file and open the VS2012 x64 Native Tools Command Prompt.
7) Execute these commands:
python configure.py
UPDATE: When execute these commands below is not working:
nmake
nmake install
Solution: I will try use pyQt4 with Qt5... because pyQt5 is in development and doesn't have support/documentation yet.
If you are facing problem with pip3 install pyqt5 then try pip3 install pyqt5==5.12.0
This solved the problem for me
If you have python installed completely, it can save you the hassle. All you need to do is enter the following command in your respective shell:
pip install pyqt5
And contrary to popular belief, AS LONG AS YOU HAVE PIP INSTALLED, you can do this on virtually any OS... Hope this helped!
easiest way, I think download Eric, unzip go to sources, open python directory, drag the install script into the python icon, not folder, follow prompts
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.
First try this in your Windows cmd window:
pip3 install pyqt5
If that is successful, it will look something like this:
C:\Windows\System32>pip3 install pyqt5

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
Another command under the cmd is:
easy_install pyqt5
If you are using canopy, use the package manager to install qt (and or pyqt)
It can be installed with below simple command:
pip3 install pyqt5
You can easily install it using Anaconda. At first install Anaconda or Miniconda on you system (download from here) and then install the pyqt as follow:
conda install pyqt
It works for both version of python (2 and 3).
