  1. Open a command console and type pip3 install PyQt5, it will start working, you should leave it like that until it reaches 100%. When this is done, a folder will automatically be created inside where you have installed Python like this \Lib\site-packages\PyQt5. With this you will only be able to execute the programs, but you will not be able to design. To download the designer, you have to type the following: pip3 install PyQt5-tools, this will create another folder \Lib\site-packages\PyQt5-tools, and here inside is the designer.exe I have already tried it and it works. Luck.

  2. The recommended way to download PyQt5 (and most python packages) is to open a terminal and type pip install pyqt5either pip3 install pyqt5. Now, you have downloaded the file with the .zip extension from the official PyQt page, what you should do is:

    1. Open a terminal and go to the folder you just unzipped.
    2. Type python configure.py, this will run the PyQt5 configuration file.
    3. Now you must build the executable, for this you write in the terminal make.
    4. Finally, it remains to install PyQt5 on your computer, for this you writemake install

    The above steps assume that you have the Python interpreter configured correctly in your system path.

    The designer is part of the QT libraries, if you download pyqt you are probably not downloading it or you have to compile it. For windows to install the designer you have to install it from https://www1.qt.io/download-open-source/?hsCtaTracking=f977210e-de67-475f-a32b-65cec207fd03%7Cd62710cd-e1db-46aa-8d4d-2f1c1ffdacea In the installer you can download the version you want of QT and the extra programs that it includes: designer, creator, studio3d... Once everything is installed, go to the windows icon > programs > QT and there you have them.

  4. Hello, I have the same problem, I already managed to make the file execute but before finishing the execution of the configure.py file I get this error

    Error: Use the --qmake argument to explicitly specify a working Qt qmake.
