如何解决git仍未跟踪和修改

Question

目前我正在使用yii2，tfs。我需要迁移到我自己的git服务器。

已设置本地git服务器

现在我git init我的本地yii2项目

现在git status会返回所有未跟踪的文件。

然后我git add .

然后我检查git status但它给了我

$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
  (commit or discard the untracked or modified content in submodules)

        modified:   vendor/kartik-v/yii2-date-range (untracked content)
        modified:   vendor/kartik-v/yii2-grid (untracked content)
        modified:   vendor/kartik-v/yii2-widget-depdrop (modified content)
        modified:   vendor/kartik-v/yii2-widget-fileinput (untracked content)

no changes added to commit (use "git add" and/or "git commit -a")

我不知道那是什么我没有对这些文件进行更改

供应商中有许多软件包，但正因如此，它们仍未被跟踪和修改。

然后我按照提示说，但它给了我

$ git commit -m "a"
On branch master
Changes not staged for commit:
        modified:   vendor/kartik-v/yii2-date-range (untracked content)
        modified:   vendor/kartik-v/yii2-grid (untracked content)
        modified:   vendor/kartik-v/yii2-widget-depdrop (modified content)
        modified:   vendor/kartik-v/yii2-widget-fileinput (untracked content)
no changes added to commit

我再次检查git status文件是否未跟踪和修改

运行git diff我得到了这个

$ git diff
