首先，您必须小心程序中缺少的空格。需要Eoln以及比较语句的空格。所以，你的程序应该是这样的：

rule_prec = '(phase ?phase)\n'

rule_prec += '?address1

rule_prec += '?address2

rule_prec += '?address3

rule_body = '(if(=(str-compare ?*pickupEvent* "no") 0) then\n'

rule_body += '(bind ?predicted-action ?action)\n'

rule_body += '(bind ?*current-action* ?predicted-action)\n'

rule_body += '(bind ?ex-tool ?tool)\n'

rule_body += 'else\n'

rule_body += '(bind ?actual-action ?action)\n'

rule_body += '(bind ?s-tool ?tool)\n'

rule_body += '(retract ?address1 ?address2 ?address3)\n'

rule_body += '(if (and (= (str-compare ?predicted-action ?actual-action) 0) \

(=(str-compare ?ex-tool ?s-tool) 0)) then\n'

rule_body += '(updateAction ?*current-action* ?actual-action)\n'

rule_body += 'else\n'

rule_body += '( if (not (= (str-compare ?predicted-action ?actual-action) 0)) then\n'

rule_body += '(updateAction ?*current-action* ?actual-action)\n'

rule_body += '(assert (You have mistake: incorrect action))\n'

rule_body += '(bind ?*number-of-mistakes* (+ ?*number-of-mistakes* 1)))\n'

rule_body += '(if (not (= (str-compare ?ex-tool ?s-tool) 0)) then\n'

rule_body += '(updateAction ?*current-action* ?actual-action)\n'

rule_body += '(assert (You have mistake: incorrect surgical device))\n'

rule_body += '(bind ?*number-of-mistakes* (+ ?*number-of-mistakes* 1))\n'

rule_body += ')))\n'其次，如果您正在使用PyClip并对CLIPS感到满意，请使用以下行来获取规则的真实CLIPS错误消息。我尝试解决您的问题，但规则的模式和操作部分存在一些问题。

import logging.config

engine = clips.Environment()

try:

rule_name = 'rule_1'

rule_prec = '(phase ?phase)\n'

rule_prec += '?address1

rule_prec += '?address2

rule_prec += '?address3

rule_body = '(if(=(str-compare ?*pickupEvent* "no") 0) then\n'

rule_body += '(bind ?predicted-action ?action)\n'

rule_body += '(bind ?*current-action* ?predicted-action)\n'

rule_body += '(bind ?ex-tool ?tool)\n'

rule_body += 'else\n'

rule_body += '(bind ?actual-action ?action)\n'

rule_body += '(bind ?s-tool ?tool)\n'

rule_body += '(retract ?address1 ?address2 ?address3)\n'

rule_body += '(if (and (= (str-compare ?predicted-action ?actual-action) 0) \

(=(str-compare ?ex-tool ?s-tool) 0)) then\n'

rule_body += '(updateAction ?*current-action* ?actual-action)\n'

rule_body += 'else\n'

rule_body += '( if (not (= (str-compare ?predicted-action ?actual-action) 0)) then\n'

rule_body += '(updateAction ?*current-action* ?actual-action)\n'

rule_body += '(assert (You have mistake: incorrect action))\n'

rule_body += '(bind ?*number-of-mistakes* (+ ?*number-of-mistakes* 1)))\n'

rule_body += '(if (not (= (str-compare ?ex-tool ?s-tool) 0)) then\n'

rule_body += '(updateAction ?*current-action* ?actual-action)\n'

rule_body += '(assert (You have mistake: incorrect surgical device))\n'

rule_body += '(bind ?*number-of-mistakes* (+ ?*number-of-mistakes* 1))\n'

rule_body += ')))\n'
