要解决这个问题，请按照以下步骤操作：

1. 提交或暂存本地更改：对于已更改的跟踪文件（knowledge_base/info.db, knowledge_base/samples/vector_store/ChatLaw-Text2Vec/index.faiss, knowledge_base/samples/vector_store/ChatLaw-Text2Vec/index.pkl），您可以选择提交这些更改或者使用git stash暂存它们。

   提交更改：

   git add <文件名>
   git commit -m "提交信息"
   

   暂存更改：

   git stash
   

2. 处理未跟踪的文件：对于未跟踪但合并时会被覆盖的文件（knowledge_base/ForeignLaw/vector_store/ChatLaw-Text2Vec/index.faiss, knowledge_base/ForeignLaw/vector_store/ChatLaw-Text2Vec/index.pkl），您需要将这些文件移动到其他位置或者删除它们。

   移动文件：

   mv <文件名> <新位置>
   

   删除文件：

   rm <文件名>
   

完成这些步骤后，您应该可以成功地从dev28分支拉取代码。
