python3 关于问题jupyter notebook Traceback (most recent call last)

 遇到用pip安装完jupyter 然后运行jupyter notebook命令，出现以下错误：

Traceback (most recent call last):
  File "e:\py3\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

 网上查资料，发现是markupsafe有问题，卸载重装还是有问题，再搜索有人说是编码问题，我之前在装jupyter就

动过python3里的__init__.py代码改utf-8为gbk，难道又要改？仔细看了看原文

作者是用Git bash成功了，我想了想没用git bash，下面有评论转换cmd命令：chcp 65001 

,也就是将cmd转化为utf-8,尝试了下，然后重装markupsafe 然后启动notebook，成功了
