無法直接在 Mac 上的終端中運行 Jupyter notebook

Question

我想在終端中使用jupyter notebook在我的 mac 上運行 jupyter notebook，但是如果我運行這段代碼，它會給我一個錯誤：

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'

但是如果我使用/usr/local/bin/python3.7 -m jupyter notebook ，那么它可以工作。

我知道可能是因為我的電腦上有幾個版本的python，或者是因為jupyter的路徑不正確，但我不知道如何處理。

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

如果我嘗試通過brew uninstall jupyter或pip3 uninstall jupyter然后pip3 install jupyter ，它仍然無法正常工作。

如果我再次安裝 jupyter，它會顯示：

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

如果我想在 pyCharm 中運行.ipynb 文件，我也會收到同樣的錯誤：

我認為這是同樣的問題，因為我無法在終端中直接運行jupyter notebook 。 這個問題一直困擾着我很多，我搜索了很多，但我仍然無法弄清楚。 我想知道我是否可以更改jupyter命令的路徑？ 如果有人能回答這個問題會很有幫助。

提前致謝！

您可以檢查 python.exe 是否已添加到 path.Environment Variables >>> System variables >>> path.（這是用於 Windows）但我認為應該有類似的東西。
