pyltp0.2.1安装后无法使用

这是控制台的
PS E:\shixixiangmu> pip install pyltp==0.2.1
Requirement already satisfied: pyltp==0.2.1 in e:\coding\anaconda\lib\site-packages (0.2.1)

这是运行结果
from pyltp import Segmentor, Postagger, Parser, NamedEntityRecognizer, SementicRoleLabeller
ModuleNotFoundError: No module named 'pyltp'

from pyltp import Segmentor, Postagger, Parser, NamedEntityRecognizer, SementicRoleLabeller

1. 是否pyltp安装在环境A，但是代码运行用的是环境B
2. 尝试卸载重新安装，或者更换版本
