How can I display the version of my Jupyter notebook and run cells in Jupyter notebooks? I get an error: bad interpreter
提问by charlesdarwin
I have installed Anaconda and I use the conda environments and the conda command to install software.
我已经安装了 Anaconda，我使用 conda 环境和 conda 命令来安装软件。
When I type:
jupyter notebook --version
当我输入：
jupyter notebook --version
I get the following error:
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
I can open a jupyter notebook by typing: jupyter notebook xyz.ipynbbut I cannot run any cells. The cell is marked with *after I run it. Soon, this message appears in a pop-up box:
我可以通过键入以下内容打开 jupyter 笔记本：jupyter notebook xyz.ipynb但我无法运行任何单元格。*运行后，该单元格被标记为。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.
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.
I get this in the terminal after opening a jupyter notebok:
打开 jupyter 笔记本后，我在终端中得到了这个：

You can check it with conda list ipython
你可以检查它 conda list ipython
回答by Jai
- This is definitely a path issue : You have your anacondda python interpreter path in
/Users/cr517/anaconda/bin/python - But your jupyter is pointing to
/Users/cr517/.local/bin/jupyterbut it should have pointed to/Users/cr517/anaconda/bin/jupyter - Run the following command
gedit /Users/cr517/anaconda/bin/jupyter - Check the first line of the opened file which will have the hardcoded path of jupyter and check whether the path in the file is correct or not
- If the path is not
/Users/cr517/anaconda/bin/jupyterthan make it/Users/cr517/anaconda/bin/jupyter - But the problem may not solve here because there are other jupyter files if you do
ls *jupyter*many of these files have the hardcoded path which might be wrong which might be reason why you are able to open he ipynb but cannot create the cell - This is too much work to do ... to manually change path for every file
- Just reinstall anaconda and your problem will be solved
- In case you are reinstalling run this
bash Anaconda....sh -b -p "Users/cr517/anaconda"
- 这绝对是一个路径问题：您的 anacondda python 解释器路径在
/Users/cr517/anaconda/bin/python - 但是你的 jupyter 指向
/Users/cr517/.local/bin/jupyter但它应该指向/Users/cr517/anaconda/bin/jupyter - 运行以下命令
gedit /Users/cr517/anaconda/bin/jupyter - 检查打开文件的第一行，该行将包含 jupyter 的硬编码路径，并检查文件中的路径是否正确
- 如果路径
/Users/cr517/anaconda/bin/jupyter不是使它/Users/cr517/anaconda/bin/jupyter - 但是问题在这里可能无法解决，因为如果您执行
ls *jupyter*这些文件中的许多具有硬编码路径的其他 jupyter 文件，这可能是错误的，这可能是您能够打开 ipynb 但无法创建单元格的原因 - 这是太多的工作要做...手动更改每个文件的路径
- 只需重新安装anaconda，您的问题就会解决
- 如果您要重新安装，请运行此
bash Anaconda....sh -b -p "Users/cr517/anaconda"
