无法在 Mac 上的终端中直接运行 Jupyter notebook

Question

我想在终端中使用jupyter notebook 在我的mac 上运行jupyter notebook，但是如果我运行这段代码，它会给我一个错误：

vlan-2625-10-16-106-253:~ brandon$ jupyter notebook
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 5, in <module>
    from notebook.notebookapp import main
ModuleNotFoundError: No module named 'notebook'

但如果我使用/usr/local/bin/python3.7 -m jupyter notebook，那么它就可以工作。

我知道可能是因为我的电脑有好几个版本的python，也可能是因为jupyter的路径不对，但是不知道怎么处理。

vlan-2625-10-16-106-253:~ brandon$ which jupyter
/usr/local/bin/jupyter
vlan-2625-10-16-106-253:~ brandon$ which python3
/usr/local/bin/python3

如果我尝试通过brew uninstall jupyter 或pip3 uninstall jupyter 然后pip3 install jupyter 卸载jupyter，它仍然不起作用。

如果我再次安装 jupyter，它会显示：

vlan-2625-10-16-106-253:~ brandon$ pip3 install jupyter

如果我想在 pyCharm 中运行 .ipynb 文件，我也会收到同样的错误：

我认为这与我无法在终端中直接运行 jupyter notebook 相同。这个问题一直困扰着我很多，我搜索了很多，但我仍然无法弄清楚。我想知道我是否可以更改jupyter 命令的路径？如果有人能回答这个问题会很有帮助。

提前致谢！

您可以检查是否在路径上添加了 python.exe。环境变量 >>> 系统变量 >>> 路径。（这是用于 windows）但我认为应该有类似的东西。
