关于jinja2高版本api变化导致notebook导出html失败的问题

最新jinja2版本已经到了3.1.2,但是nbconvert引用的应该是老版本,具体代码报错如下

python 复制代码
Type "help", "copyright", "credits" or "license" for more information.
>>> import nbconvert
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\gw00305123\Anaconda3\lib\site-packages\nbconvert\__init__.py", line 4, in <module>
    from .exporters import *
  File "C:\Users\gw00305123\Anaconda3\lib\site-packages\nbconvert\exporters\__init__.py", line 3, in <module>
    from .html import HTMLExporter
  File "C:\Users\gw00305123\Anaconda3\lib\site-packages\nbconvert\exporters\html.py", line 14, in <module>
    from jinja2 import contextfilter
ImportError: cannot import name 'contextfilter' from 'jinja2' (C:\Users\gw00305123\Anaconda3\lib\site-packages\jinja2\__init__.py)

nubconvert会从jinja2导入一个叫contextfilter的东西,但是新版本已经没有了,这会导致我导出一个notebook到html时报错,具体报错信息如下

python 复制代码

从报错信息中并不能看出什么问题,但是从报错信息的上一行,有个导入nbconvert的语句,于是推测跟nbconvert有关,于是有了开头的测试语句,发现是jinja2的版本问题,于是降了一个版本,装了3.0.3,解决!!!!
