如何显示Jupyter笔记本的版本并在Jupyter笔记本中运行单元格？我得到一个错误:糟糕的翻译

Question

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

我可以通过键入打开一个jupyter笔记本:jupyter notebook xyz.ipynb但我不能运行任何单元格.*我运行后标记了单元格.很快,此消息显示在弹出框中:

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.

我打开一个jupyter notebok后在终端得到这个:

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:

jupyter notebook 在Web浏览器中打开我的目录,但不创建新的笔记本.

我输入python --version了终端并获得:

Python 3.6.3 :: Anaconda custom (x86_64)

Answer 1

你可以试试这个:

jupyter --version

Answer 2

*如何查看iPython版本

你可以检查一下 conda list ipython
