Mac上jupyter更改python环境

需要将jupyter的内核从python3.6改为python3.7
1. 查询内核配置文件的位置
jupyter kernelspec list

2. 找到jupyer的配置文件kernel.json
cd /usr/local/share/jupyter/kernels/python3
ls

3. 对kernel.json文件进行添加
"/usr/local/bin/python"

{
 "argv": [
  "/usr/local/bin/python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3",
 "language": "python"
}
