PYTHON配置环境变量无效？

Question

见下图，明明已经配置了,而且安装时选择了添加到环境中，path也添加了相应路径，就是不成功

Answer 1

将其设置为默认python，可选
cmd命令打开vi ~/.bash_profile进行修改
# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
# PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
PATH="/usr/local/bin:${PATH}"
export PATH
PATH=”/usr/local/Cellar/python/3.6.4_4/bin:${PATH}”
export PATH
alias python="/usr/local/Cellar/python/3.6.4_4/bin/python3.6"

cmd命令：
source ~/.bash_profile
添加zsh配置文件：
HenrydeMacBook% vim ~/.zshrc
HenrydeMacBook% cat ~/.zshrc
source ~/.bash_profile
