克隆存储库时，可以使用--recursive标志。此参数强制git克隆存储库中所有已定义的子模块。

git clone --recursive git@repo.org:your_repo.git

克隆后，有时子模块分支可能会发生更改，因此在其之后运行以下命令：

git submodule foreach "git checkout master"

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。

[快速回答]

您可以使用此命令克隆包含所有子模块的repo：

git clone --recursive YOUR-GIT-REPO-URL

或者，如果您已经克隆了项目，则可以使用：

git submodule init
git submodule update

如果子模块被添加到分支中，请确保将其包含在克隆命令中。。。

git clone -b <branch_name> --recursive <remote> <directory>

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
