mod-是什么导致 go 中出现“内部错误：未能找到...的嵌入文件”之类的错误消息？

我已经在我的分支上工作了几天。与此同时，master分支已经发展，所以我这样做了git rebase master。

输出CONFLICT在某些文件中显示 s：

Auto-merging vendor/modules.txt
CONFLICT (content): Merge conflict in vendor/modules.txt
Auto-merging go.sum
CONFLICT (content): Merge conflict in go.sum
Auto-merging go.mod
CONFLICT (content): Merge conflict in go.mod
error: could not apply 1bd673ea... update vendor folder
Resolve all conflicts manually, mark them as resolved with
update vendor folder
"git add/rm ", then run "git rebase --continue".
You can instead skip this commit: run "git rebase --skip".
To abort and get back to the state before "git rebase", run "git rebase --abort".
Could not apply 1bd673ea... update vendor folder

解决冲突后，我会go mod tidy然后go mod vendor. 结果是一条奇怪的消息：

internal error: failed to find embedded files of github.com/grpc-ecosystem/grpc-gateway/v2/runtime: //go:build comment without // +build comment

这意味着什么？我如何避免？
