I've tried to install both, pymqi and py3mqi and I'm getting the same error. I'm using Python 3.6, 32-bit. Also, I have MQ Client installed as well as Visual Studio 15. There is the following path on my disk: C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC, but PlatformSDK\\lib is missing.

You should use pymqi which now supports Python 3 and has many additional fixes. py3mqi was a fork of a much older version of pymqi when it did not support Python 3. — JoshMc, Jul 18 '19 at 18:44
JoshMc: Yes, I have the client installed. Also, I'm getting the same error when trying to install pymqi. — GeoGeek, Jul 18 '19 at 18:46
It appears it fails when it needs to compile the C library at the end, do you have C support in your VS 14? — JoshMc, Jul 18 '19 at 18:47
I just noticed that I had a trial version of VS 15 which also expired. Is VS required for pymqi to work? — GeoGeek, Jul 18 '19 at 18:58
It is is required to compile it. I think you can install a pre-compiled package as well. — JoshMc, Jul 18 '19 at 19:02

As JoshMC states pymqi now supports Python 3, and should be what you are using. pymqi binds to the MQI C Layer, and requires access to MQ C Header files as well as a C compiler / linker, when it installs.

The error you are getting is a common Visual Studio error, when the Windows Platform SDK has not been installed. Essentially installing Visual Studio does not mean that you have installed the C / C++ compiler, and you need to do that also.

Once I reinstalled VS with C/C++ compiler, I was able to install the pymqi package. Thanks! – GeoGeek Jul 22 '19 at 13:09

Did you consider trying to install Visual Studio 2019 with the python and c package?

That is needed for some packages.

An other possible option is, that py3mqi isn't available for Python 3.6.*
