ModuleNotFoundError: No module named 'encodings'


Thanks Thomas,

You are right, this seems the Python home configuration issue.

One more question.

Is there a way I can catch the error ( Fatal Python error: initfsencoding:
..) as exception in the c code ?

try{
    Py_Initialize();
}catch(xxx)
{

}


Thanks
