在本地主机上启动 Jupyter 笔记本会导致"[Errno 49] 无法分配请求的地址"，但是 ip=127.0.0.1 有效

Question

当尝试启动Jupyter笔记本时，我收到以下错误

$ Jupyter Notebook
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.7/bin/jupyter-notebook", line 11, in <module>
sys.exit(main())
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/jupyter_core/application.py", line 268, in launch_instance
return super(JupyterApp, cls).launch_instance(argv=argv, **kwargs)

sock.bind(sockaddr)
OSError: [Errno 49] Can't assign requested address

然而，当我指定127.0.0.1(即不是"localhost"(的ip地址Jupyter Notebook --ip=127.0.0.1时，它可以很好地工作。

此外，当我ping localhost时，它会返回本地主机实际上是127.0.0.1。

$ ping localhost
PING localhost.localdomain (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.034 ms

我检查了etc/hosts和private/etc/hosts，都没有指定localhost(或任何相关内容(。

当我在PyCharm中运行Jupyter Notebooks时，我正试图解决这个问题，但你不能创建一个简单的快捷方式来在127.0.0.1副"localhost"上运行。(我知道没有简单的快捷方式，如果我错了，请纠正我(我可以在Pycharm中的127.0.0.1上启动，但它需要多个步骤，而且很麻烦。我只想通过它的默认配置"localhost"来实现这一点。

为您的jupyter笔记本生成配置文件

$ jupyter notebook --generate-config

用你最喜欢的编辑器跳转到这个新的配置文件

$ nano ~/.jupyter/jupyter_notebook_config.py

在文件中添加以下行，使其成为在上侦听的默认服务器

c.NotebookApp.ip = '127.0.0.1'
