Python “问题”；pycountry.db"；——属性错误：'；模块'；对象没有属性'；db'； 编辑：原来这是reddit和pycountry的最新（0.14）版本的某种兼容性问题。轻松安装0.12.1，现在一切正常

我正在尝试设置reddit实例，但遇到了此错误

这是stacktrace

第16行

类国家（pycountry.db.Database）：

前面有

导入pycountry.db

上面的几行，所以如果“pycountry.db.Database”抛出了一个关于模块对象没有属性db的错误，那么

导入

行不也应该抛出一个错误吗？我能做什么？

您的本地目录中是否有另一个名为

pycountry.py

的文件？没有，原来是reddit和pycountry 0.14的兼容性问题。谢谢你的帮助：）
