centos7下python3.7.2的安装记录

1. 下载 3.7.2
2. 解压
3. 安装python的依赖库（如果编译python过程中出错，很容易知道缺失什么库)

yum install zlib-devel bzip2-devel openssl-devel ncurese-devel uuid libffi libffi-devel  
yum install tcl tcl-devel tk tk-devel

4. 默认情况下，编译出来的python库是静态库。这在后期开发需要用到python so库，那么会很不方便，因此最好配置为so库。同时也在安装时指定安装目录。

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

5. 开始编译安装

make && make install

6. 创建软链接

ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3

如果在编译中出现如下错误

In file included from /home/888/Downloads/Python-3.7.2/Modules/_uuidmodule.c:8:0:
/usr/include/uuid.h:94:24: error: conflicting types for ‘uuid_t’

                        ^

这里把解决方案直接贴出来
即修改如下文件 ./Modules/_uuidmodule.c

#define PY_SSIZE_T_CLEAN

#include "Python.h"
#ifdef HAVE_UUID_UUID_H
#include <uuid/uuid.h>
#endif
#ifdef HAVE_UUID_H
#include <uuid.h>
#endif

//修改为

#define PY_SSIZE_T_CLEAN
#include "Python.h"
#ifdef HAVE_UUID_UUID_H
#include <uuid/uuid.h>
// #endif
// #ifdef HAVE_UUID_H
#else
#include <uuid.h>
#endif
