我对 Pyke 完全陌生，我正在尝试运行一个简单的代码，但它给了我一个syntax error. 我从 sourceforge.com 的源代码安装了 pyke3，我使用了 python 3.10、python 3.97 并且都给出了相同的错误。这是所有文件的代码：

1-驱动程序.py

from pyke import knowledge_engine

engine = knowledge_engine.engine(__file__)


def rules():

    engine.reset()

    engine.activate('rules.krb')

2-facts.kfb

has_age_of("some name", 38)
was_born_in("some name", 1976)
has_number_of_file("some name", 470)
has_gravidity_of("some name", Gs)
has_parity_of("some name", "p9 + 0")
has_gestational_age_of("some name", "10 weeks + 3 days")
works_as("some name", "some occupation")
has_blood_group("some name", "A+ve")

3-rules.krb

# KRB.krb

the_age
    use aged_with($age, $name)
    when
    facts.has_age_of($name, $age)

在我运行驱动程序的地方发生了这种情况：

writing [compiled_krb]/facts.fbc

请帮忙。
