idea配置python sdk 环境错误 mac

1. idea plugins 安装python插件
2. 当clone 一个项目后发现
   项目的python 版本是3+ 自己本地的python是2+
3. 更新python
   brew upgrade python3
4. 配置环境变量
   open ～/.bash_profie

配置python3的环境变量

# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/usr/local/bin/:${PATH}"
export PATH

alias python="/usr/local/bin/python3"

source ~/.bash_profile
更新配置时，出现报错

N/A: version "N/A -> N/A" is not yet installed.

You need to run "nvm install N/A" to install it before using it.

于是install 一下自己需要的版本号的node

例如

nvm install nvm install 12.14.1

再次更新一下配置文件
source ~/.bash_profile

此刻

~/Documents/regional-it/demos/dso(master*) »which python                                                                                                                        yuanli.dai@YuanlideMacBook-Pro

5. 在idea中new project 配置sdk的环境
   或者 通过已clone的项目中 cmd ;
   配置python的sdk
