CentOS 7安装Python 3.7

1. 官网下载源码包

2.解压

3. 安装Python 3.7依赖的包

    yum -y install libffi-devel openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc

进入python3.7解压后的目录 

   ./configure --prefix=/usr/local/python3 --enable-shared CFLAGS= fPIC --with-ssl

make && make install

4.如果报错

python3: error while loading shared libraries: libpython3.5m.so.1.0: cannot open shared object fil

解决方法：cd  /etc/ld.so.conf.d

　　　　　vim python3.conf 

   　　　　添加库文件路径 /usr/local/Python3/lib

      　　　退出保存

　　　　  运行ldconfig
