解决ImportError: cannot import name ‘soft_unicode‘ from ‘markupsafe‘

不能打开Jupyter Notebook，报错：

Traceback (most recent call last):

ImportError: cannot import name 'soft_unicode' from 'markupsafe' (C:\ProgramData\Anaconda3\lib\site-packages\markupsafe\__init__.py)

 

解决方法：

查看这个库是否存在：  pip show markupsafe

查看，已经安装，则重新安装一下

若存在重新安装  python -m pip install markupsafe==2.0.1

再次启动jupyter notebook，成功进入。
