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

Question

我一直在尝试设置一个ipython服务器以下几个教程（因为没有一个完全是我的情况）。几天前，我确实设法使它达到了启动的程度，但后来无法通过url访问它。今天它不再发布了，我找不到更多关于这个特定错误的信息：

Traceback (most recent call last):

关于安装，我已经安装了ipython的anaconda发行版，pyzmq&；tornado库。我已经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/'}

我真的不知道到哪里去寻找线索了——而且我可能还没有更深入地理解这一切是如何解决的。我的最终目标是使用this questionon的答案来完成apache背后的设置，并最终将其连接到colaboratory，但似乎应该首先启动它。

非常感谢您的帮助：）

Answer 1

升级IPython时我也遇到了同样的问题。在写答案的那一刻，它是一个链接到最新版本的bug。如果发生类似的问题，您希望切换回稳定版本3.2.1：

pip uninstall -y IPython
pip install ipython==3.2.1

• 注意：选项-y表示“是，我想卸载”，没有交互。
• 注2：可能在ImportError: No module named notebook.notebookapp中重复

Answer 2

所以要关闭这个线程，如果它对任何人都有帮助的话，我的错误是盲目地按照教程安装和使用了ipython的开发版本，以为我使用的是我之前安装的anaconda实例（甚至不在我的路径上）。

无论如何我：

• 已卸载该ipython dev实例
• 将anaconda/bin添加到我的zsh路径（将其添加到~/.zshrc-这就是为什么安装后它甚至不在我的路径中）//此时服务器启动正常，但我无法在浏览器中访问它>；>；防火墙问题。
• 在我的防火墙中打开了我选择的端口（通常是linode或ubuntu的帮助）

现在一切都很好。

Answer 3

这样可以解决问题：

pip install jupyter
