Question

我安装了Anaconda python发行版。但是，执行＆＃34; ipython notebook＆＃34;我无法成功执行它并且系统产生以下错误。我一无所知，出了什么问题？

感谢。

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为自己提供的答案的基础上，因为我似乎无法找到自己的根本原因

您可以尝试编辑ipython个人资料。在我的情况下，我必须使用以下命令创建一个配置文件：

ipython profile create

然后将以下行附加到ipython notebook配置中。在我的情况下，该文件位于~/.ipython/profile_default/ipython_notebook_config.py，这是没有名称创建的配置文件的默认位置。找到后，添加以下配置选项：

c.NotebookApp.ip = '127.0.0.1'

然后，当运行ipython notebook时，它会像往常一样打开，而不需要提供ip参数。所以你的解决方案没有太大改进，但我更喜欢这样：）

如果你真的有兴趣知道在配置或命令行中不提供ip时调用的原因或地址，你可以在同一个地方添加以下内容配置文件：

c.Application.verbose_crash=True

在我的情况下，运行ipython notebook会得到以下输出：

--> 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，它可能试图访问无效的IP。
