centos - OSError: [Errno 99] 无法分配请求的地址

问题描述

尝试jupyter notebook在 CentOS 7 上运行。它返回：

OSError: [Errno 99] Cannot assign requested address

和堆栈跟踪：

[user@desktop ~]$ jupyter notebook
Traceback (most recent call last):
  File "/home/use/anaconda3/bin/jupyter-notebook", line 6, in <module>
    sys.exit(notebook.notebookapp.main())
  File "/home/user/anaconda3/lib/python3.6/site-packages/jupyter_core/application.py", line 267, in launch_instance
    return super(JupyterApp, cls).launch_instance(argv=argv, **kwargs)
  File "/home/user/anaconda3/lib/python3.6/site-packages/traitlets/config/application.py", line 657, in launch_instance

    sockets = bind_sockets(port, address=address)
  File "/home/user/anaconda3/lib/python3.6/site-packages/tornado/netutil.py", line 197, in bind_sockets
    sock.bind(sockaddr)
OSError: [Errno 99] Cannot assign requested address

解决方案

jupyter notebook --ip=127.0.0.1 --port=8888

我必须简单地设置 ip/port 参数。该问题可能是因为它之前尝试分配的默认 IP/端口已被占用！
