Centos OS 8默认的Python版本为3.6,不符合练习的需求。现在升级到3.9。
# 下载Python3.9.9 wget https://www.python.org/ftp/python/3.9.9/Python-3.9.9.tgz tar zxvf Python-3.9.9.tgz # 安装必须的包 dnf -y install gcc zlib* libffi-devel cd Python-3.9.9/ ./configure --prefix=/usr/local/python3 --enable-optimizations make make install # 删除原先的Python3和pip3 rm -rf /usr/bin/python3 ln -s /usr/local/python3/bin/python3 /usr/bin/python3 rm -rf /usr/bin/pip3 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
查看Python3和Pip3是否正确的被安装:
python3 --version pip3 --version
