python - 索引错误: list index out of range for pyswip library

Question

首先，我现在遇到了太多 python 错误。这种情况对我的动力产生了相当负面的影响。我正在尝试运行在此错误中发现的专家系统。但我收到以下错误。我查看了其他解决方案，但它也不适合我。

药店专家系统: https://github.com/enzoftware/pyswipl_drugstore

代码:

from flask import Flask, render_template, flash, request
from wtforms import Form, TextField, TextAreaField, validators, StringField, SubmitField
from pyswip import Prolog
import os
import time

# App config.
DEBUG = True
app = Flask(__name__)
app.config.from_object(__name__)
app.config['SECRET_KEY'] = '7d441f27d441f27567d441f2b6176a'



class ReusableForm(Form):

    name = TextField('Name:', validators=[validators.required()])

    @app.route("/", methods=['GET', 'POST'])
    def hello():
        form = ReusableForm(request.form)
        if request.method == 'POST':

            name=request.form['name']
            fiebre = request.form.get('fiebre') == 'on'
            nausea = request.form.get('nausea') == 'on'
            diarrea = request.form.get('diarrea') == 'on'
            headache = request.form.get('headache') == 'on'
            print(fiebre, nausea, diarrea, headache)
            os.system('swipl -q -t "program" console.pl')
        if form.validate():
            f = open("file.txt", "r")
            disease = f.read()
            print(disease)
            flash('Hola ' + name + ', por tus sintomas podemos deducir que tienes '+ disease)
        else:
            flash('Error: Debes ingresar tu nombre. ')

        return render_template('hello.html', form=form)

if __name__ == "__main__":
    app.run()

错误:

            paths = [os.path.join(path, 'bin', dllName)
                     for dllName in dllNames]
            for path in paths:

                    return (path, None)

Answer 1

Windows 解决方案:

1. 确保您的 Python 和 SWI Prolog 都是 32 位或 64 位。

2. 转到 core.py 的第 180 行并将该行更改为:

   paths = [os.path.join(programFiles, r'swipl\bin', dllName)
