如何显示Jupyter笔记本的版本并在Jupyter笔记本中运行单元格?我收到一个错误:翻译错误 [英] How can I display the version of my Jupyter notebook and run cells in Jupyter notebooks? I get an error: bad interpreter

问题描述

我已经安装了Anaconda，并且使用了conda环境和conda命令来安装软件.

I have installed Anaconda and I use the conda environments and the conda command to install software.

当我输入时: 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

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内容来打开jupyter笔记本:jupyter notebook xyz.ipynb，但是我无法运行任何单元格.运行它后，该单元格会用*标记.很快，此消息出现在弹出框中:

I can open a jupyter notebook by typing: jupyter notebook xyz.ipynb but I cannot run any cells. The cell is marked with * after I run it. Soon, this message appears in a pop-up box:

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.

我在打开jupyter notebok之后在终端中得到了这个信息:

I get this in the terminal after opening a jupyter notebok:

实际上没有/Users/cr517/anaconda/envs/snakes/bin/python，但是为什么Jupyter Notebook尝试使用此功能?我这里有运行良好的Python:

Indeed there is no /Users/cr517/anaconda/envs/snakes/bin/python but why is Jupyter Notebook trying to use this? I have a well-functioning Python here:

jupyter notebook在网络浏览器中打开我的目录，但没有创建新的笔记本.

jupyter notebook opens my directory in a web browser but does not create a new notebook.

我在终端中键入python --version并得到:

I typed python --version in the terminal and got:

Python 3.6.3 :: Anaconda custom (x86_64)

推荐答案

*如何检查iPython版本

您可以使用conda list ipython
