1。 準備編譯環境
yum groupinstall ‘development tools’
yum install bzip2-devel expat-devel gdbm-devel ncurses-devel openssl-devel readline-devel sqlite-devel tk-devel xz-devel zlib-devel wget
yum install libffi-devel -y
2。 下載python3。9
wget https：//www。python。org/ftp/python/3。9。1/Python-3。9。1。tgz
3。 解壓下載後的檔案
tar xf Python-3。9。1。tgz
4。 編譯安裝
。/configure ——prefix=/usr/local/python3。9
make && make altinstall
5。 建立軟連線
ln -s /usr/local/python3。9/bin/python3。9 /usr/local/bin/python3
ln -s /usr/local/python3。9/bin/pip3 /usr/local/bin/pip3
6。測試並驗證
