Composer安装依赖后Git操作遇目录删除标记及换行符转换警告的解决方法求助

我执行了composer require logger命令，安装过程看起来是正常的：

但之后我运行git status查看状态，却得到了这样的结果：

On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        deleted:    my_project_directory

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   composer.json
        modified:   composer.lock
        modified:   config/bundles.php
        modified:   symfony.lock

接着我尝试执行这个添加文件的命令：
git add composer.json composer.lock config/bundles.php symfony.lock config/packages/monolog.yaml

结果又弹出了一堆换行符转换的警告：

warning: in the working copy of 'composer.json', LF will be replaced by CRLF the next time Git touches it
warning: in the working copy of 'composer.lock', LF will be replaced by CRLF the next time Git touches it
warning: in the working copy of 'config/bundles.php', LF will be replaced by CRLF the next time Git touches it
warning: in the working copy of 'symfony.lock', LF will be replaced by CRLF the next time Git touches it
warning: in the working copy of 'config/packages/monolog.yaml', LF will be replaced by CRLF the next time Git touches it

有没有大佬能告诉我该怎么解决这两个问题呀？
