使用Owlready2执行本体代码遇权限拒绝错误求助

运行Owlready2官方文档中的本体代码时，已手动指定Java路径，但调用sync_reasoner()仍触发权限拒绝错误，作为本体领域新手，需排查问题原因及解决办法。

运行代码 #

from owlready2 import *
import owlready2
# 原路径仅指向bin目录，存在配置错误
owlready2.JAVA_EXE = "C:\\Program Files\\Java\\jdk-19\\bin"

onto = get_ontology("http://test.org/onto.owl")

with onto:
    class Drug(Thing):
        def take(self): print("I took a drug")
    class ActivePrinciple(Thing):
         pass

    class has_for_active_principle(Drug >> ActivePrinciple):
         python_name = "active_principles"

    class Placebo(Drug):
        equivalent_to = [Drug & Not(has_for_active_principle.some(ActivePrinciple))]
        def take(self): print("I took a placebo")

    class SingleActivePrincipleDrug(Drug):
        equivalent_to = [Drug & has_for_active_principle.exactly(1, ActivePrinciple)]
        def take(self): print("I took a drug with a single active principle")

    class DrugAssociation(Drug):
        equivalent_to = [Drug & has_for_active_principle.min(2, ActivePrinciple)]
        def take(self): print("I took a drug with %s active principles" % len(self.active_principles))

acetaminophen   = ActivePrinciple("acetaminophen")
amoxicillin     = ActivePrinciple("amoxicillin")
clavulanic_acid = ActivePrinciple("clavulanic_acid")

AllDifferent([acetaminophen, amoxicillin, clavulanic_acid])

drug1 = Drug(active_principles = [acetaminophen])
drug2 = Drug(active_principles = [amoxicillin, clavulanic_acid])
drug3 = Drug(active_principles = [])

close_world(Drug)

sync_reasoner()

错误情况 #

调用sync_reasoner()时出现权限拒绝（Permission denied）错误，无法完成本体一致性检查及类自动分配。

排查及解决办法 #

• 修正Java路径配置：owlready2.JAVA_EXE需指向java.exe完整路径，而非仅bin目录，修改为：

  owlready2.JAVA_EXE = "C:\\Program Files\\Java\\jdk-19\\bin\\java.exe"
  

• 更换Java版本：高版本Java（如jdk19）可能与Owlready2依赖的HermiT推理器存在兼容性问题，建议切换至jdk8或jdk11等LTS版本。
• 提升运行权限：在Windows系统中，以管理员身份运行脚本（右键IDE或命令提示符选择「以管理员身份运行」），避免文件访问权限不足。
• 检查临时目录权限：Owlready2运行推理器时会在系统临时目录生成文件，确保当前用户对临时目录（如C:\Users\你的用户名\AppData\Local\Temp）拥有读写权限。
