使用gqlgen生成GraphQL schema时出现missing go.sum entry错误求助

问题重现 #

执行gqlgen生成命令：

go run github.com/99designs/gqlgen generate

出现以下错误：

..\..\..\..\..\go\pkg\mod\github.com\99designs\gqlgen@v0.17.33\main.go:20:2: missing go.sum entry for module providing package github.com/urfave/cli/v2 (imported by github.com/99designs/gqlgen); to add:

原因分析 #

这类错误是因为go.sum文件缺少gqlgen及其子模块依赖的校验条目，Go模块需要这些条目验证依赖包的完整性和一致性，避免依赖被篡改。

解决步骤 #

1. 安装指定版本的gqlgen，补全主模块的sum条目：

go get github.com/99designs/gqlgen@v0.17.33

2. 自动整理所有依赖，补全缺失的sum条目并清理无用依赖：

go mod tidy

3. 重新执行gqlgen生成命令：

go run github.com/99designs/gqlgen generate
