源码安装python3以及yum配置

源码安装python3以及yum 配置 1.下载python wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz tar -zxvf Python-3.7.3.tgz cd Python-3.7.3.tgz cd src 2.安装依赖 yum -y install gcc openssl-devel readline readline-devel zlib-devel libffi-devel 3.编译安装 ./configure --prefix=/usr/local/soft/python3 --with-ssl make && make install cd /usr/local/soft/python3/bin ./python3.7 4.配置环境变量 可选 vim /etc/profile.d/python3.sh export PYTHON_HOME=/usr/local/soft/python3 export PATH=$PYTHON_HOME/bin python3 5.更改默认python版本 mv /usr/bin/python /usr/bin/python2.7.5 ln -s /usr/local/soft/python/bin/python3.7 /usr/bin/python python -V Python 3.7.3 6.配置yum 更换默认python版本后,yum不能使用了 vim /usr/bin/yum 在第一个行修改 #!/usr/bin/python ==> #!/usr/bin/python2.7.5 还有另外一个地方需要修改 vim /usr/libexec/urlgrabber-ext-down #!/usr/bin/python ==> #!/usr/bin/python2.7.5 yum 可以正常使用...
