项目提交git,出现异常

The page build failed with the following error:The submodule `themes/jacman` was not properly initialized with a `.gitmodules` file.

问题通过submodule命令解决

git submodule add https://github.com/wuchong/jacman.git themes/jacman

当前工程根路径下生成一个名为“.gitmodules”的文件

[submodule "themes/jacman"]    path = themes/jacman    url = https://github.com/wuchong/jacman.git
