原因:原来安装在/目录,现在不允许
方案:
首先从迁移的项目中移动到/Users/yourname/下
/Users/yourname/anaconda3/conda中修改
from

!/anaconda3/bin/python

to

!/Users/yourname/anaconda3/bin/python

同理 对~/.bash_profile

from

export PATH="/anaconda3/bin:$PATH"

to

export PATH="/Users/yourname/anaconda3/bin:$PATH"

conda init bash 或者 conda init zsh

$ conda init bash

no change     /Users/yourname/anaconda3/condabin/conda
no change     /Users/yourname/anaconda3/bin/conda
no change     /Users/yourname/anaconda3/bin/conda-env
no change     /Users/yourname/anaconda3/bin/activate
no change     /Users/yourname/anaconda3/bin/deactivate
no change     /Users/yourname/anaconda3/etc/profile.d/conda.sh
no change     /Users/yourname/anaconda3/etc/fish/conf.d/conda.fish
no change     /Users/yourname/anaconda3/shell/condabin/Conda.psm1
no change     /Users/yourname/anaconda3/shell/condabin/conda-hook.ps1
no change     /Users/yourname/anaconda3/lib/python3.6/site-packages/xontrib/conda.xsh
no change     /Users/yourname/anaconda3/etc/profile.d/conda.csh
modified      /Users/yourname/.bash_profile

运行几遍,如果jupyter notebook 起不来的话,更新一下

conda update --prefix /Users/yourname/anaconda3 anaconda

这里,因为anaconda迁移了位置,所以kernel的path也要更新在/Users/yourname/anaconda3/share/jupyter/kernels/下创建文件夹python2或者python3(如果有直接cd进入),修改或新建kernel.json,内容如下

{
 "display_name": "Python 2", 
 "language": "python", 
 "argv": [
  "/Users/yourname/anaconda3/envs/kf/bin/python", 
  "-m", 
  "ipykernel_launcher", 
  "-f", 
  "{connection_file}"
 ]
}

以上便可以更改anaconda位置后启动jupyter notebook了

部分错误如下:

FileNotFoundError: [Errno 2] No such file or directory: '~/anaconda3/envs/kf/bin/python'   
bad interpreter: /anaconda3/bin/python: no such file or directory
