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

Question

我一直试图在几个教程之后设置一个ipython服务器(因为没有一个是我的情况).几天前,我确实设法让它达到启动的程度,但之后却无法通过url访问它.今天它不再发布了,我找不到太多关于我得到的这个特定错误:

Traceback (most recent call last):

  File "build/bdist.linux-x86_64/egg/ipython_genutils/importstring.py", line 31, in import_item
ImportError: No module named notebook.notebookapp

关于设置,我已经安装了anaconda distrib的ipython,pyzmq和tornado库.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/'}

我真的不知道在哪里寻找线索 - 而且我可能对如何解决这个问题缺乏更深入的理解.我的最终目标是在SO上使用这个问题的答案来完成apache背后的设置并最终将它连接到colaboratory - 但似乎它应该首先启动.

非常感谢任何帮助:)

Answer 1

这应该解决问题:

pip install jupyter

Answer 2

我在升级IPython时遇到了同样的问题.在撰写答案的那一刻,这是一个与最新4版本相关的错误.如果出现类似问题,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:该-y选项表示"是我要卸载",没有交互.
• 注2:ImportError中可能存在重复:没有名为notebook.notebookapp的模块
