[英]How can I display the version of my Jupyter notebook and run cells in Jupyter notebooks? I get an error: bad interpreter
我已经安装了 Anaconda,我使用 conda 环境和 conda 命令来安装软件。
当我输入: jupyter notebook --version
我收到以下错误:
zsh: /Users/cr517/.local/bin/jupyter: bad interpreter: /Users/cr517/anaconda/envs/snakes/bin/python: no such file or directory 5.2.1
我可以通过键入以下jupyter notebook xyz.ipynb
打开 jupyter notebook: jupyter notebook xyz.ipynb
但我无法运行任何单元格。 运行后,该单元格标有*
。 很快,这个消息出现在一个弹出框中:
The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.
打开 jupyter 笔记本后,我在终端中得到了这个:

确实没有/Users/cr517/anaconda/envs/snakes/bin/python
但为什么 Jupyter Notebook 试图使用它? 我在这里有一个运行良好的 Python:

Available kernels:

python2 /usr/local/share/jupyter/kernels/python2
jupyter notebook
在网络浏览器中打开我的目录,但不会创建新的 notebook。
我在终端中输入python --version
并得到:
Python 3.6.3 :: Anaconda custom (x86_64)
你可以简单地做:
jupyter --version
这是我的情况下的输出:
jupyter core : 4.5.0
jupyter-notebook : 5.2.2
qtconsole : 4.5.2
ipython : 5.5.0
ipykernel : 4.10.1
jupyter client : 5.3.1
jupyter lab : not installed
nbconvert : 5.5.0
ipywidgets : 7.5.0
nbformat : 4.4.0
traitlets : 4.3.2
/Users/cr517/anaconda/bin/python
有您的 anacondda python 解释器路径/Users/cr517/.local/bin/jupyter
但它应该指向/Users/cr517/anaconda/bin/jupyter
gedit /Users/cr517/anaconda/bin/jupyter
/Users/cr517/anaconda/bin/jupyter
/Users/cr517/anaconda/bin/jupyter
ls *jupyter*
,还有其他 jupyter 文件,其中许多文件的硬编码路径可能是错误的,这可能是您能够打开 ipynb 但无法创建单元格的原因bash Anaconda....sh -b -p "Users/cr517/anaconda"
