我正在尝试将我的 first_app 提交到 Git 上。我在命令行中输入了以下内容（见下文），但我的输出表明没有什么可提交的。
new-host:first_app XXXXXX$ cd /Users/XXXXXX/rails_projects/first_app
new-host:first_app XXXXXX$ git init
Reinitialized existing Git repository in /Users/XXXXXX/rails_projects/first_app/.git/
new-host:first_app XXXXXX$ git add .
new-host:first_app XXXXXX$ git status
# On branch master
nothing to commit (working directory clean)
new-host:first_app XXXXXX$
在另一个终端中，我跑来$ rails server创建我的 first_app。为什么没有什么可承诺的？
我怎样才能解决这个问题？谢谢！
注意输出的第一行：
重新初始化现有的 Git 存储库
您已经在该目录中有一个 git 存储库，并且它没有未提交的更改。
做完之后
git add .
您需要提交刚刚暂存的更改：
git commit -m "my first commit"
git show您可以使用该命令查看最新提交。
也许您之前在第一次创建 git 存储库时添加并提交了？
我能够通过以下方式重现这一点：
durrantm.../aaa$ git init

请注意您所看到nothing to commit的 a 之后的结尾如何。git add .
一个“修复”是删除 git 存储库并重新开始，当您这样做时，您可以正常提交最终版本，例如：
durrantm.../aaa$ rm -rf .git/
durrantm.../aaa$ l

看起来你已经在那个文件夹中有一个初始化的 git repo。它可能已经提交了所有文件，当您“重新初始化”时，您实际上只是重新启动了 git 服务。也许。尝试更改其中一个文件，然后键入以下命令：
cd /Users/XXXXXX/rails_projects/first_app/
git add .
git commit -a -m "commit message"
那应该承诺。您可能需要将 CD 命令更改为指向 firstapp/git/，但老实说，我不记得了。祝你好运！
