python - 每次我运行 "jupyter notebook"时，为什么我总是在 mac os 上得到这个？

Question

每次我在 mac 操作系统上运行“jupyter notebook”时，为什么总是出现此错误？

案例:

1. 我有 python2.x 并且安装了 python3.7 (所以，我这里有两个命令)
2. 我用 pip 安装了 jupyter
3. 当我输入 jupyter Notebook 命令时，我总是收到这些错误

错误:

来自warp-x :如果您不介意手动打开浏览器，可以在启动笔记本时传递 --no-browser:$ jupyter notebook --no-browser。然后，您可以打开浏览器，手动在浏览器(通常为 localhost:8888)中导航到笔记本并开始工作。
