Jupyter错误：“没有名为jupyter_core.paths的模块”

Question

尝试打开Jupyter Notebook (OSX 10.11.4)时出现以下错误：

$ jupyter-notebook
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/Users/geotheory/Library/Python/2.7/lib/python/site-packages/notebook/__init__.py", line 25, in <module>
    from .nbextensions import install_nbextension
  File "/Users/geotheory/Library/Python/2.7/lib/python/site-packages/notebook/nbextensions.py", line 23, in <module>
    from jupyter_core.paths import jupyter_data_dir, jupyter_path, SYSTEM_JUPYTER_PATH
ImportError: No module named jupyter_core.paths

这曾经很管用。你知道怎么诊断吗？

Answer 1

我也遇到了同样的问题，只需在macOS终端中使用pip install jupyter即可修复。

Answer 2

我面临着同样的问题，并能够通过以下步骤解决。

conda create -n py36 python=3.6
conda activate py36
conda install notebook ipykernel jupyterlab

Answer 3

我也遇到过类似的问题。基本上，我通过卸载python2.7并重新安装更新的python和IPython版本解决了这个问题。

有关如何通过Mac命令行有效卸载python2.7的详细信息，请访问此处：How to uninstall Python 2.7 on a Mac OS X 10.6.4?

通过命令行重新安装所需版本的IPython。在我的例子中，我还需要通过以下方式重新安装Jupyter：

$ pip install jupyter

祝好运。
