在安装 nltks 停用词和 punkt 时出现 AttributeError 错误：模块“打字”没有属性“_SpecialForm”？

如何解决在安装 nltks 停用词和 punkt 时出现 AttributeError 错误：模块“打字”没有属性“_SpecialForm”？

我正在尝试在 NLTK 中下载 stopword 和 punkt，但收到 AttributeError 错误：模块 'typing' 没有属性 '_SpecialForm' .

将 PyCharm IDE 与 Python 3.7 版和NLTK 3.5 版结合使用。
如果您需要任何其他信息，请告诉我

下载NLTK的脚本如下：-

import nltk
nltk.download('stopwords')
nltk.download('punkt')

完整的错误日志如下：-
