今天跟代码，修改了vendor中的某些文件，然后撤销了，可能某些没有还原成原先的。yii2 的目录/vendor/ 是 gitignore 的，如何才可以将 /vendor 还原或者更新，使用 `composer 可否？

Delete the vendor.. Then composer update --prefer-dist
shellcomposer update
shell
composer update
Next time, develop a good habit and try not to touch the code in the vendor. Only overwrite the reload. If you really need to make changes, make a backup first
