git - 空字符串不是有效的路径规范

Question

看完Git - git-submodule Documentation ，我决定将我之前项目的两个文件导入到我新项目的根目录下，因为我不想手动同步这两个文件。但是，当我执行以下命令时出现错误:

$ git submodule add -b master -f --name latexci -- https://github.com/donizyo/LaTeX-Travis.git .
fatal: empty string is not a valid pathspec. please use . instead if you meant to match all paths
usage: git submodule--helper clone [--prefix=<path>] [--quiet] [--reference <repository>] [--name <name>] [--depth <depth>] --url <url> --path <path>

    --prefix <path>       alternative anchor for relative paths
    --path <path>         where the new submodule will be cloned to
    --name <string>       name of the new submodule
    --url <string>        url where to clone the submodule from
    --reference <repo>    reference repository
    --dissociate          use --reference only while cloning
    --depth <string>      depth for shallow clones
    -q, --quiet           Suppress output for cloning a submodule
    --progress            force cloning progress

我正在使用 Git Bash 2.19.1.windows.1 来执行 git 命令。

路径 (.) 应该是一个不存在的文件夹，例如 Latex-Travis。

相反，此处“.”被解释为空路径(因为它引用了您的父存储库)，如 ruby-git/ruby-git issue 345 中所示:

This really was deprecated since Git 2.1.6:

An empty string as a pathspec element that means "everything" i.e. 'git add ""', is now illegal. We started this by first deprecating and warning a pathspec that has such an element in 2.11 (Nov 2016).

我不知道在父仓库文件夹中直接添加了子模块:我总是习惯于添加为父仓库子文件夹。
