can't load a plugin 'Meshio'

I’m a complete beginner when it comes to programming and after doing the steps here:
tianyikillua/paraview-meshio: Generic mesh reader / writer for ParaView (

I get this error:

Generic Warning: In vtkPVPythonAlgorithmPlugin.cxx, line 184
Failed to load Python plugin:

Traceback (most recent call last):

It looks like we try to load the Python script; this fails with an exception (that we print, good). But we then go and try to load it as a DLL…bad. However, we only return bool from vtkPVPythonAlgorithmPlugin::LoadPlugin, so telling “not Python” from “Python, but failed” is not possible.
