Jupyter notebook Jupyter笔记本内核或路径混乱

我正在使用jupyter笔记本和蟒蛇安装的python3.7。如果我打开anaconda应用程序，选择基本环境并单击

openwithJupyter Notebook

，它将毫无问题地运行。 如果我从windows命令行键入

jupyter notebook

，我会收到以下消息：

Traceback (most recent call last):
  File "C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in <module>
    from notebook.notebookapp import main
  File "C:\Users\z5044992\AppData\Roaming\Python\Python37\site-packages\notebook\notebookapp.py", line 64, in <module>
    from tornado import httpserver
  File "C:\Users\z5044992\AppData\Roaming\Python\Python37\site-packages\tornado\httpserver.py", line 29, in <module>
    import ssl
  File "C:\Users\z5044992\AppData\Local\Continuum\anaconda3\lib\ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ImportError: DLL load failed: The specified module could not be found.

在环境变量中，我有一个名为

PATH

的用户变量，它包括：

C:\Users\z5044992\AppData\Local\Continuum\anaconda3
C:\Users\z5044992
C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts
C:\Users\z5044992\AppData\Roaming\Python\Python37\site-packages\

    C:\Users\z5044992\AppData\Local\Continuum\anaconda3
    C:\Users\z5044992\AppData\Local\Continuum\anaconda3\pkgs
    C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts
    C:\Users\z5044992\AppData\Roaming\Python\Python37\site-packages\IPython\extensions
    C:\Users\z5044992\.ipython

以及一个称为PATH的系统变量，该变量包括：

C:\Users\z5044992\AppData\Local\Continuum\anaconda3
C:\Users\z5044992
C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts
C:\Users\z5044992\AppData\Roaming\Python\Python37\site-packages\

    C:\Users\z5044992\AppData\Local\Continuum\anaconda3
    C:\Users\z5044992\AppData\Local\Continuum\anaconda3\pkgs
    C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts
    C:\Users\z5044992\AppData\Roaming\Python\Python37\site-packages\IPython\extensions
    C:\Users\z5044992\.ipython

我遗漏了什么吗？

连一句评论都没有？我欢迎大家就如何重新组织这个问题提出建议，以获得一些意见。我觉得我永远都不会完全理解python路径，尽管它不应该很复杂！
