Preface

I recently encountered a problem at work. When installing python pyqt5, it actually prompted a failure. I had no choice but to find a solution. method, I found that there are students who also encountered this problem on the Internet, so I summarized the solution and shared it. I won’t go into details below, let’s take a look at the detailed introduction:

Discover the problem

In the past, the installation command was done with one pip command, and the dependent libraries were automatically installed, but I encountered a problem when installing pyqt5

After downloading pyqt5, it will prompt that the suitable SIP version cannot be found

 Could not find a version that satisfies the requirement sip>=4.19 (from pyqt5) (from versions: ) No matching distribution found for sip>=4.19 (from pyqt5)

Manualpip install sipcannot be installed, and it will prompt that the suitable version cannot be found. This is strange

I downloaded all the whl file versions of SIP, and when I used pip to install them, it prompted that they were incompatible with the current machine platform and could not be installed.

Then I downloaded the source code to compile and install. In order to be able to compile, I also installed mingw32 so that I can use make, gcc and other commands. After compilation and installation, it still cannot be installed through pip install pyqt5, and the same error is prompted.

So I thought about downloading the source code, compiling and installing pyqt5. Compiling this was more troublesome. I spent a long time configuring it, but it couldn’t be compiled. .

Solution

After struggling for a long time, how did you solve it in the end?

Uninstalled python3.4, downloaded and installed python3.5, and thenpip install pyqt5One command to do it

Old versions of Python cannot install the latest pyqt5 mean?

After writing the code for python3.5 and packaging it with pyinstaller, WIN7 runs normally but XP computer cannot.

The prompt cannot locate the program input point Getfinalpathnamebyhandlew in the dynamic link library kernel32.dll.

Baidu said: python3.5 no longer supports XP and requires python3.4.
