python 2.7.3 的 jupyter 笔记本问题

Question

尝试运行 jupyter notebook 时突然出现此错误。 我也安装了最新的 python 但是这个 mac-python 问题是我猜想从 python2 运行的问题。 任何指向维护两个 python 的指南/教程的链接也会有所帮助，但现在正在寻找此修复程序。

  File "/anaconda2/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/anaconda2/lib/python2.7/site-packages/notebook/notebookapp.py", line 60, in <module>
    from tornado import httpserver
  File "/anaconda2/lib/python2.7/site-packages/tornado/httpserver.py", line 33, in <module>
    from tornado.http1connection import HTTP1ServerConnection, HTTP1ConnectionParameters
  File "/anaconda2/lib/python2.7/site-packages/tornado/http1connection.py", line 30, in <module>
    from tornado import iostream
  File "/anaconda2/lib/python2.7/site-packages/tornado/iostream.py", line 40, in <module>
    from tornado.netutil import ssl_wrap_socket, _client_ssl_defaults, _server_ssl_defaults
  File "/anaconda2/lib/python2.7/site-packages/tornado/netutil.py", line 44, in <module>
    _client_ssl_defaults = ssl.create_default_context(
AttributeError: 'module' object has no attribute 'create_default_context'```
