AttributeError: module ‘ahocorasick‘ has no attribute ‘Automaton‘

    在使用ahocorasick.Automaton()时，总是提示AttributeError: module 'ahocorasick' has no attribute 'Automaton'

 原本安装的模块是ahocorasick-python，而ahocorasick.Automaton()用的是pyahocorasick

 安装pyahocorasick，pip install pyahocorasick，安装后运行还是有这个错误，需要卸载ahocorasick-python
