一，官方文档:
https://doc.thinkphp.cn/v8_0/setup.html二，查看当前的php版本是否满足升级条件:
1,文档中的环境要求
2,查看本地的php版本:
liuhongdi@lhdpc:~$ /usr/local/soft/php8/bin/php --version
PHP 8.1.1 (cli) (built: Dec 20 2021 16:12:16) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.1, Copyright (c) Zend Technologies
with Zend OPcache v8.1.1, Copyright (c), by Zend Technologies当前版本是 8.1.1 ，显然符合条件
3,查看当前项止的thinkphp版本:
liuhongdi@lhdpc:/data/php/tpapibase$ php think version
v6.1.0说明：刘宏缔的架构森林—专注it技术的博客，

三，升级thinkphp
1,升级原项目到可用的最新版本:
liuhongdi@lhdpc:/data/php/tpapibase$ composer update topthink/framework

liuhongdi@lhdpc:/data/php/tpapibase$ php think version
v6.1.4可以看到升级完成后版本是v6.1.4
2,修改composer.json
"require": {
"php": ">=8.0.0",
"topthink/framework": "^8.0",
"topthink/think-orm": "^3.0",
"topthink/think-filesystem": "^2.0"
},
"require-dev": {
"symfony/var-dumper": ">=4.2",
"topthink/think-trace":"^1.0"
},对require需要用到的库的版本调整，我的配置版本号如上，
“topthink/think-filesystem”: “^2.0”, 这一行是我手动添加上的,
说明：这些版本号是从哪里来的？
用下面的命令新创建一个thinkphp8项目，从composer.json中就看到了
liuhongdi@lhdpc:/data/php$ composer create-project topthink/think tp83,删除composer.lock
liuhongdi@lhdpc:/data/php/tpapibase$ rm composer.lock4,升级前查看当前各库的版本:
