为什么它不让我提交我的子模块？

Question

所以我最近做了：

git submodule foreach git submodule foreach git pull origin master

我得到了一个巨大的输出，因为它拉和更新这些子模块的最新和最伟大的。然后我做了：

vagrant@vagrantpress:/vagrant/Freya-Vagrant$ git status
On branch master
Your branch is up-to-date with 'origin/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:   local-dev/content/mu-plugins/Freya-MU (modified content)
        modified:   local-dev/content/themes/freya-theme (modified content)

no changes added to commit (use "git add" and/or "git commit -a")
vagrant@vagrantpress:/vagrant/Freya-Vagrant$ git commit -a
On branch master
Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:
        modified:   local-dev/content/mu-plugins/Freya-MU (modified content)
        modified:   local-dev/content/themes/freya-theme (modified content)

no changes added to commit
vagrant@vagrantpress:/vagrant/Freya-Vagrant$ git add -A
vagrant@vagrantpress:/vagrant/Freya-Vagrant$ git commit -a
On branch master
Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:
        modified:   local-dev/content/mu-plugins/Freya-MU (modified content)
        modified:   local-dev/content/themes/freya-theme (modified content)

no changes added to commit
vagrant@vagrantpress:/vagrant/Freya-Vagrant$

但正如你所看到的，它不会提交，因为显然没有变化？我不明白这个。，到底怎么回事？

这是因为更改在git子模块项目中，而不是根项目中。

在https://git-scm.com/book/en/v2/Git-Tools-Submodules的文档之后，您可能希望执行如下操作：

cd local-dev/content/mu-plugins/Freya-MU
git checkout master # or some other branch
git submodule update --remote --merge

# make edits, e.g.:
vi README.md 
git commit -m "test" README.md

git submodule update --remote --rebase
git push --recurse-submodules=check  # follow the output from this command
