centos安装python3.7
一、安装依赖包
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
yum install libffi-devel -y
二、下载python3.7包
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
三、安装
tar -zxvf Python-3.7.0.tgz
cd Python-3.7.0
./configure
make&&make install
四、配置环境变量
mv /usr/bin/python /usr/bin/python.bak
ln -s /usr/local/bin/python3 /usr/bin/python
mv /usr/bin/pip /usr/bin/pip.bak
ln -s /usr/local/bin/pip3 /usr/bin/pip
五、配置yum依赖
将/usr/bin/python改为/usr/bin/python2.7。（两个文件一样修改）
vim /usr/libexec/urlgrabber-ext-down
vi /usr/bin/yum
