3.1 Download Python3
URL: https://www.python.org/downloads/

Unzip the downloaded compressed file
tar -xf Python-3.6.3.tgz
3.3 Enter the decompressed directory, compile and install##
cd Python-3.6.3./configure --prefix=/usr/local/python3
3.4 Compile and install##
make
make install
3.5 Build python3 soft chain##
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
3.6 Add /usr/local/python3/bin to PATH
vim ~/.bash_profile
Edit the content and add python3 executable files.
# Get the aliases and functions
if[-f ~/.bashrc ]; then
.~ /.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH
Press ESC, type: wq and press Enter to exit.
After the modification, remember to execute the following command to make the modification in the previous step take effect:
source ~/.bash_profile
3.7 Check whether Python3 and pip3 are normally available##
python3 -V
pip3 -V
# python3 -V
Python 3.6.1
# pip3 -V
pip 9.0.1from/usr/local/python3/lib/python3.6/site-packages(python 3.6)
If it doesn't work, create a pip3 soft link:
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
