安装pip3和openpyxl 

wget --no-check-certificate https://bootstrap.pypa.io/get-pip.py

python3 get-pip.py
 
pip3 -V
 
#如果出现
pip3 -V

-bash: pip3: command not found
 
使用find / -name pip
 
find / -name pip

/usr/local/python3/lib/python3.6/site-packages/pip
/usr/local/python3/bin/pip
/software/Python-3.6.2/Tools/msi/pip
/root/.cache/pip
 
#做pip的软链接
 
ln -s /usr/local/python3/bin/pip /usr/bin/pip3
 
pip3 -V
pip 18.0 from /usr/local/python3/lib/python3.6/site-packages/pip (python 3.6)
 
 
Centos 的python和pip的升级安装都已完成

pip3 install openpyxl
