can't find method

[miuru0]

I got this problem: can't find method greet
appending bogus greet to list of constants

when running pyc-xasm --pyc-file test .\compiled_code.pyasm

this is the code that generated compiled_code.pyasm

source_code = """
def greet():
    print("Hello, world!")
"""

compiled_code = compile(source_code, "<string>", "exec")
pyc_file = "compiled_code.pyasm"
with open(pyc_file, "w") as file:
    xdis.std.disassemble(compiled_code, file=file)

and this is the compiled_code:
