python - 无法在 OSX 上成功执行 ipython 笔记本命令

Question

我安装了 Anaconda python 发行版。但是，执行“ipython Notebook”后，我无法成功执行它，并且系统产生以下错误。我一头雾水，到底出了什么问题？

谢谢。

or send an email to the mailing list at ipython-dev@scipy.org


You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

这只是建立在 @Abhay Bhadani 已经为自己提供的答案的基础上，因为我自己似乎找不到根本原因

您可以尝试编辑您的 ipython 配置文件。就我而言，我必须使用以下命令创建配置文件:

ipython profile create

然后将以下行附加到 ipython 笔记本配置中。在我的例子中，该文件位于 ~/.ipython/profile_default/ipython_notebook_config.py ，这是在没有名称的情况下创建的配置文件的默认位置。找到后，附加以下配置选项:

c.NotebookApp.ip = '127.0.0.1'

然后，当运行ipython Notebook时，它将照常打开，无需提供 ip 参数。所以你的解决方案并没有太大的改进，但我更喜欢这样:)

如果您确实想知道在配置或命令行中未提供 IP 时为什么或调用什么地址，您可以在同一内容中附加以下内容配置文件:

c.Application.verbose_crash=True

就我而言，运行ipython笔记本会给出以下输出:

--> 228     return getattr(self._sock,name)(*args)
    global getattr = undefined
    self._sock = <socket object, fd=6, family=2, type=1, protocol=6>
    name = 'bind'
    args = (('192.168.77.104', 8888),)
229
230 for _m in _socketmethods:
231     p = partial(meth,_m)
232     p.__name__ = _m
233     p.__doc__ = getattr(_realsocket,_m).__doc__
234     m = MethodType(p,None,_socketobject)
235     setattr(_socketobject,_m,m)
236
237 socket = SocketType = _socketobject
238
239 class _fileobject(object):
240     """Faux file object attached to a socket object."""
241
242     default_bufsize = 8192
243     name = "<socket>"

error: [Errno 49] Can't assign requested address

这只是给了我一个提示，表明它可能正在尝试访问无效的 IP。
