I am trying to install PyQt5 on windows 7 with Python 3.4. I already installed SIP, but when I try to run the python configure command for PyQt5 I get the following error:

Answer 1

Try executing that same command, but from the "Visual Studio Command Prompt". Its a shell with the corresponding enviroment already setted. If not, the prebuilt binary packages are a simpler way

Answer 2

You can try to run the prebuilt installer. The prebuilt installer at Windows system is an exe file ,so you can just click on the next button and you will make it work well.
