我确实尝试了所有方法并阅读了有关此问题的所有先前帖子。
首先，我尝试安装 Anaconda，并尝试运行 Jupiter，但它说未找到命令。
然后我尝试
pip install Jupyter
我收到了一个很长的错误...

然后我尝试
pip install --user jupyter
它没有抛出任何错误，但当我尝试运行 Jupyter ntoebook 时仍然得到
-bash: jupyter: command not found
另一件奇怪的事情是，我似乎完全无法将 Python 从 2.7 更新到 3，这是一个单独的问题，我在这里不寻求答案，尽管它们可能相关？
谢谢你的帮助！！
答案1
问题解决了 - 事实证明，安装新软件后重新启动计算机 99% 就可以解决问题！！
