提示：错误信息
Laravel刚开始用的php7.3.4这个版本,后来切换到PHP7.1.9这个版本。
解决方案：
我删除了 vendor 文件夹，然后执行了以下指令：
composer install --ignore-platform-reqs
出现如下报错信息
最终解决办法
我删除了 vendor 文件夹，删除 composer.lock 文件。
PHP CLi 命令行执行：composer install
PS D:\\phpstudy_pro\\WWW\\Workerman\\tt.cc\\tla> composer install
No composer.lock file present. Updating dependencies to latest instead of installing from lock file. See https://getcomposer.org/install for more information.
