step 1 - Check your php version. If your laravel is old , then it wont support 7.x, you need to switch (checkthis if you are using mac) to PHP 5.6 in this case.
第 1 步 - 检查您的 php 版本。如果您的 laravel 是旧的，那么它将不支持 7.x，在这种情况下，您需要切换（如果您使用的是 mac，请检查此选项）到 PHP 5.6。
Step 2 - remove composer.lock and run composer install
第 2 步 - 删除 composer.lock 并运行 composer install

I assume the problem can come from multiple sources. In my case, I had a syntax error in my config/app.php. Reverted to a previous version and the remade my edits.
我认为问题可能来自多个来源。就我而言，我的 config/app.php 中有一个语法错误。恢复到以前的版本并重新进行了我的编辑。

The only thing that command does is delete the bootstrap/cache/services.phpfile, if it exists. Most likely, the file exists, but the permissions aren't set correctly to allow you to delete it.
该命令唯一能做的就是删除bootstrap/cache/services.php文件（如果存在）。最有可能的是，该文件存在，但权限设置不正确以允许您删除它。
