git子模块已经存在，但它不存在吗？

Question

我有git：https://github.com/bbialek/dotfiles，我想为vim的病原体插件创建子模块。

cd ~/dotfiles/vim
git submodule add https://github.com/tpope/vim-pathogen .vim

上面写着：

‘’vim/.‘vim’已经存在于索引中。

是因为我已经在./dotfiles/vim/.vim/bundle/*中有子模块了吗？

我的.gitmodules

    [submodule "vim/.vim/bundle/nerdtree"]
    path = vim/.vim/bundle/nerdtree
    url = https://github.com/scrooloose/nerdtree
[submodule "vim/.vim/bundle/vim-autoformat"]
    path = vim/.vim/bundle/vim-autoformat
    url = https://github.com/Chiel92/vim-autoformat
[submodule "vim/.vim/bundle/vim-colors-solarized"]
    path = vim/.vim/bundle/vim-colors-solarized
    url = https://github.com/altercation/vim-colors-solarized
[submodule "vim/.vim/bundle/vim-sensible"]
    path = vim/.vim/bundle/vim-sensible
    url = https://github.com/tpope/vim-sensible
[submodule "vim/.vim/bundle/YouCompleteMe"]
    path = vim/.vim/bundle/YouCompleteMe
    url = https://github.com/Valloric/YouCompleteMe
[submodule "tmux/.tmux/plugins/tpm"]
    path = tmux/.tmux/plugins/tpm
    url = https://github.com/tmux-plugins/tpm

不能在声明的子模块路径中注册子模块(如vim/.vim/bundle/nerdtree)。

由于已经使用了.vim的多个子模块，因此需要为.vim子模块回购使用不同的文件夹。
