laravel版本升级后 php artisan 所有命令都失败

本地laravel环境从 laravel6 升级到 laravel7 后，没问题，可以访问，artisan命令可以执行

[root@localhost total_smp]# php artisan cache:clear
Application cache cleared!
[root@localhost total_smp]# composer dumpautoload

[root@localhost total_smp]# php artisan 
Laravel Framework 7.30.4

Usage:
  command [options] [arguments]
.....

将代码用git提交后(所有必要的文件都提交，如vender的内容，测试环境不需要再执行额外的操作)，测试环境执行任何php artisan命令都报错

PHP Warning:  Uncaught ErrorException: require(/data/smp/total_smp/vendor/composer/../markbaker/matrix/classes/src/Functions/adjoint.php): 
failed to open stream: No such file or directory in /data/smp/total_smp/vendor/composer/autoload_real.php:71
......

访问web页面也直接报错500

按照网上推荐的解决方式，有三种

1. 首先判断是否是缓存造成的，运行composer clearcache命令进行缓存清除后，运行项目还是会报相同错误
2. 把vendor目录删掉，使用composer install重新安装整个项目依赖，这个对于我的测试环境可以解决，但是会造成修改一系列文件，但是在该测试环境因为没有给开通可以提交代码的权限，所以放弃
3. composer update进行项目扩展更新，针对我的情况还是不行，报错

最终原因（针对我的情况），目录文件/data/smp/total_smp/vendor/composer/../markbaker/matrix/classes/src/Functions/adjoint.php确实再git部署的环境上没找到，但是我在我自己的本地环境上确实存在，因此，最大原因是git提交代码时忽略了大小写，导致一些文件没有提交（比如上面....../markbaker/matrix/classes/src/Functions目录的文件），因此修改本地git忽略大小写配置

#直接把git的忽略大小写关了：
git config core.ignorecase false

在查看git状态

Administrator@SD-20190505CHCR total_smp $ git st
位于分支 dev
您的分支与上游分支 'origin/dev' 一致。

未跟踪的文件:
  （使用 "git add <文件>..." 以包含要提交的内容）

        vendor/markbaker/matrix/classes/src/Functions/
        vendor/markbaker/matrix/classes/src/Operations/

真发现还有没提交的文件了。。提交到版本控制，在测试环境拉完最新代码后没问题了！！！
记录一下，避免以后又踩坑
