只需在项目目录中执行这些操作。

$ git submodule init
$ git submodule update

1.git子模块初始化2位子模块更新

或者可能git存储-ugit拉动原点主机数字存储p

迟交的答复

// git CLONE INCLUDE-SUBMODULES ADDRESS DESTINATION-DIRECTORY
git clone --recursive https://USERNAME@bitbucket.org/USERNAME/REPO.git DESTINATION_DIR

正如我刚刚花了整整一个小时和一个朋友在一起闲逛：即使你有BitBucket的管理员权限，也要克隆原始存储库，并使用拥有回购的人的密码。发现你撞上了这个地雷陷阱，我很恼火：P

我建议：

# - git submodule init initializes your local configuration file to track the submodules your repository uses, it just sets up the configuration so that you can use the git submodule update command to clone and update the submodules.
git submodule init
# - git submodule update --init initializes your local configuration file and clones the submodules for you, using the commit specified in the main repository.
#   note, command bellow will not pull the right branch -- even if it's in your .gitmodules file, for that you need remote. Likely because it looks at the origin (pointer to remote) in github for the available branches.
#   note, bellow pulls the submodules if you didn't specify them when cloning parent project, ref: https://youtu.be/wTGIDDg0tK8?t=119
git submodule update --init

如果您有子模块的特定分支，请将其更改为：

# - git submodule init initializes your local configuration file to track the submodules your repository uses, it just sets up the configuration so that you can use the git submodule update command to clone and update the submodules.
git submodule init

# - The --remote option tells Git to update the submodule to the commit specified in the upstream repository, rather than the commit specified in the main repository.
#git submodule update --init --remote
git submodule update --init --recursive --remote meta-dataset

对于测试的完整示例：

# decided against this because it seems complicated

# - note to clone uutils with its submodule do (cmd not tested):
cd $HOME
git clone --recurse-submodules git@github.com:brando90/ultimate-utils.git

# - git submodules
cd $HOME/diversity-for-predictive-success-of-meta-learning

# - in case it's needed if the submodules bellow have branches your local project doesn't know about from the submodules upstream
git fetch

# -- first repo
# - adds the repo to the .gitmodule & clones the repo
git submodule add -f -b hdb --name meta-dataset git@github.com:brando90/meta-dataset.git meta-dataset/

# - ref for init then update: https://stackoverflow.com/questions/3796927/how-do-i-git-clone-a-repo-including-its-submodules/3796947#3796947
#git submodule init

#git submodule update --init --remote
git submodule update --init --recursive --remote meta-dataset

# - check we are using the right branch https://stackoverflow.com/questions/74998463/why-does-git-submodule-status-not-match-the-output-of-git-branch-of-my-submodule
git submodule status
cd meta-dataset
git branch  # should show hdb
cd ..

# pip install -r $HOME/meta-dataset/requirements.txt

# -- 2nd repo, simplified commands from above
git submodule add -f -b hdb --name pytorch-meta-dataset git@github.com:brando90/pytorch-meta-dataset.git pytorch-meta-dataset/

git submodule init
git submodule update --init --recursive --remote meta-dataset

git branch  # should show hdb
cd ..

# pip install -r $HOME/pytorch-meta-dataset/requirements.txt

我在GitHub存储库中遇到了同样的问题。我的帐户缺少SSH密钥。该过程是

生成SSH密钥向GitHub帐户添加新的SSH密钥

然后，您可以使用子模块克隆存储库（gitclone--递归YOUR-git-REPO-URL）

or

运行gitsubmodule init和gitsubmodule update以获取已克隆存储库中的子模块。

如何“git克隆”回购，包括其子模块？

（我把它作为一个独立的答案，因为我认为这在git中很重要）

可悲的是，但在很多情况下，那些不太知情的克隆人会错过外在的东西：

vc大便(https://github.com/dirk-thomas/vcstool)数字子报表(https://github.com/ingydotnet/git-subrepo)git链接(https://github.com/chronoxor/gil).gitsvnextmodule（由smartgit处理）。git外部(https://github.com/develer-staff/git-externals)git x模块(https://gitmodules.com/)等等

作为备份，无法创建裸克隆（--bare）+完全递归（--recursive）来镜像（--mirror）所有引用（而不仅仅是所有外部引用）：使用--recursive和--bare克隆git存储库

因此，对于git，没有一种内置的方法可以完全接受外部依赖关系。这意味着没有一种方法可以完全备份任何随机git存储库。
