1，先安裝依賴包

yum -y install zlib*

yum -y install nano wget epel-release gcc zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel xz-devel libffi-devel

2，下載python3.8檔案 wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz
3，解壓 tar -xvf ./Python-3.8.5.tgz
4，新建資料夾 mkdir /usr/local/python3
5，進入資料夾 cd Python-3.8.5
6，編譯 ./configure --prefix=/usr/local/python3 --with-ssl
7，安裝 make && make install

#如果提示沒有按照make執行以下命令
yum -y install gcc automake autoconf libtool make
yum install gcc gcc-c++

8，刪除衝突檔案
rm -rf /usr/bin/python3
rm -rf /usr/bin/pip3
9，設定軟連線
ln -s /usr/local/python3/bin/python3.8 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip3

10，升級pip
/usr/local/python3/bin/python3.8 -m pip install --upgrade pip

11，安裝依賴包

pip3 install wheel

12，檢視版本

python3 -V

pip3 -V
