周末在家里做了一些工作，周一到办公室，执行git更新办公室电脑上的代码时，报错了

> git submodule update –init faceapi-rpc-cpp/dependencies/common\_source\_cpp/  
> error: Server does not allow request for unadvertised object 50db78feb453236961657c9f2ff8c50ed0bbebaf  
> Fetched in submodule path ‘faceapi-rpc-cpp/dependencies/common\_source\_cpp’, but it did not contain 50db78feb453236961657c9f2ff8c50ed0bbebaf. Direct fetching of that commit failed.

怎么也没想明白是怎么回事儿，  
在网上找了半天也没有找到解决办法，但大概知道就是在更新子模块时，服务器上找不到submodule`common_source_cpp`指定的commit `50db78feb453236961657c9f2ff8c50ed0bbebaf`.  
怎么会找不到提交呢？我笔记本上的代码都提交了呀。  
其实就是项目主模块记录的submodule中的提交`50db78feb453236961657c9f2ff8c50ed0bbebaf`在服务器上的submodule`common_source_cpp`中并不存在。  
想到这里我明白原因了：  
我在家里工作时主项目的代码push到了git server,但忘记将submodule `common_source_cpp`也push到git server.  
所以造成主项目中记录的submodule的HEAD超前，所以找不到指定的commit.

解决办法很简单：回头到笔记本上把submodule`common_source_cpp`push一下

再执行 `git submodule update`就正常了。
