Git 不再暂存我的文件，并将它们报告为 "deleted" 和 "untracked" 。为什么会这样，以及如何避免呢？

Question

我已经成功地完成了一个简单的git repo，有4个文件，添加并提交了很多次。

但是最近，每当我尝试添加一些文件，然后询问状态时，git都会报告我所有的文件为已删除和未跟踪。所以我不能添加我的文件。

$ git add ch28_NN.py
$ git add Challenge28.py
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)
    deleted:    .gitignore
    deleted:    Challenge28.py
    deleted:    ch28_NN.py
    deleted:    requirements.txt
Untracked files:
  (use "git add <file>..." to include in what will be committed)
    .gitignore
    Challenge28.py
    ch28_NN.py
    requirements.txt

我现在唯一的解决方案是进行备份并尝试重置以卸载。

我想知道出了什么问题，以及如何避免它。

Answer 1

我最终找到了一个解决方案，它不是在两个建议的(但有趣的)链接中讨论的那个。

我发现:

• 使用git add --all工作良好的阶段

• 使用git add -A不工作…即使它应该相当于第一个

• 我仍然有问题，任何时候我用简单的命令git add filename添加我的文件，我仍然通过添加一切(git add --all)来解决它，所以它有点麻烦(既不方便，又无法解释)，但我仍然可以继续我的工作。

下面的例子说明了哪些是有效的，哪些是无效的，哪些重现了问题，以及哪些解决了问题:

$ git add --all           # WORKED FINE
