ipython 服务器无法启动：没有名为 notebook.notebookapp 的模块

我一直在尝试按照几个教程设置 ipython 服务器（因为没有一个完全符合我的情况）。几天前，我确实设法将其启动，但随后无法通过 url 访问它。今天它不再启动了，我找不到太多关于我得到的这个特定错误的信息：

Traceback (most recent call last):

关于设置，我安装了 ipython、pyzmq 和 Tornado 库的 anaconda distrib。我创建了一个配置文件 nbserver，配置文件如下 - ipython.config.py：

c = get_config()
c.IPKernalApp.pylab = 'inline'
c.NotebookApp.certfile = u'/home/ludo/.ipython/profile_nbserver/mycert.pem'
c.NotebookApp.ip = '*'
c.NotebookApp.open_browser = False
c.NotebookApp.password = u'sha1:e6cb2aa9a[...]'
c.NotebookApp.port = 9999
c.NotebookManager.notebook_dir = u'/var/www/ipynb/'
c.NotebookApp.base_project_url = '/ipynb/'
c.NotebookApp.base_kernel_url = '/ipynb/'
c.NotebookApp.webapp_settings = {'static_url_prefix':'/ipynb/static/'}

我真的不知道该去哪里寻找线索了——而且我可能对这一切是如何运作的缺乏更深入的了解。我的最终目标是使用答案这个问题 https://stackoverflow.com/questions/23890386/how-to-run-ipython-behind-an-apache-proxySO 完成 apache 后面的设置并最终将其连接到协作实验室 - 但似乎它应该首先启动。

非常感谢您的帮助:)

这应该可以解决问题：

pip install jupyter
