出现ImportError: cannot import name 'MailMerge' from 'mailmerge'该怎么办

Traceback (most recent call last):
  File "G:\python\wd - MB6.py", line 2, in <module>
    from mailmerge import MailMerge  # 引用邮件处理模块
ImportError: cannot import name 'MailMerge' from 'mailmerge' (G:\python\python程序\lib\site-packages\mailmerge\__init__.py)

网上查了好多还是没解决

pip install docx-mailmerge
