Wheels built from different versions of pip cannot be installed successfully

See original GitHub issue

Pip version: 19.0.3
Python version: 3.6.0
Operating system: windows7, 64bit

I build a wheel using pip wheel numpy command and copy it to another win7, 64bit computer with 7.0.0 pip and 3.6.0 python to install, it fails however. When I upgrade target pip into version 19.1.1, it succeed.

It seems that wheel file must be built and installed through pip with the same major version number(of course python version should meet first), is that right?

In theory, as long as the wheel tags are compatible with the target environment, pip will be able to install the wheel.

But at the moment, you haven’t even explained what you mean by “it fails however”. So it’s pointless speculating what might be going wrong.

Pip 71. is pretty ancient, and IIRC the valid tag values have changed since then (specifically the cp36m ABI tag is new). So yes, you should upgrade pip to get a version compatible with current tag standards. This won’t affect pure Python wheels like six, as they don’t have ABI tag restrictions.

Thank you very much for your patience and explanation. I will try to avoid these problems in the future.
