# 指定軟連接
[hilqiqi0@crawler-001 Python-3.6.8]$ sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python3

# 配置環境PATH
[hilqiqi0@crawler-001 Python-3.6.8]$ vim .bash_profile
# export PATH前一行添加這一句：PATH=$PATH:$HOME/bin:/usr/local/python3/bin

# 使環境PATH生效
[hilqiqi0@crawler-001 Python-3.6.8]$ source ~/.bash_profile


[hilqiqi0@crawler-001 python3.6]$ python3 -V
