如何更新kratos版本 实战-从 kratos-v2.0.0-rc1 升级到 kratos-v2.0.0

1. 查看下当前版本

   jw@jianwei seckill (main) $ kratos -v
   kratos version v2.0.0-rc1

2. 查看go.mod文件 cat go.mod

   go 1.16
   require (
   ...
   github.com/go-kratos/kratos/v2 v2.0.0-rc1
   ...
   )

3. 升级kratos构建工具
   go get -u github.com/go-kratos/kratos/cmd/kratos/v2@latest
4. 查看构建工具版本是否更新

   jw@jianwei service (main) $ kratos -v
   kratos version v2.0.0

5. 升级项目中的kratos版本

   cd /go/src/project # 项目的路径
   go get -u github.com/go-kratos/kratos/v2@latest

6. 查看项目中的kratos版本是否更新成功 cat go.mod

   go 1.16
   require (
   ...
   github.com/go-kratos/kratos/v2 v2.0.0
   ...
   )

升级后测试构建项目出现错误

jw@jianwei service (main) $ make run
cd cmd/server/ && go run .
../../../../../../pkg/mod/github.com/aliyun/alibaba-cloud-sdk-go@v1.61.18/sdk/responses/json_parser.go:11:2: missing go.sum entry for module providing package github.com/json-iterator/go (imported by github.com/aliyun/alibaba-cloud-sdk-go/sdk/responses); to add:
    go get github.com/aliyun/alibaba-cloud-sdk-go/sdk/responses@v1.61.18
../../../../../../pkg/mod/go.opentelemetry.io/otel/metric@v0.20.0/config.go:18:2: no required module provides package go.opentelemetry.io/otel/unit; to add it:
    go get go.opentelemetry.io/otel/unit
../../../../../../pkg/mod/github.com/nacos-group/nacos-sdk-go@v1.0.8/common/logger/logger.go:28:2: missing go.sum entry for module providing package go.uber.org/zap (imported by github.com/nacos-group/nacos-sdk-go/common/logger); to add:

解决: 根据提示更新对应的库go get

出现错误but does not contain package

jw@jianwei service (main) $ go get go.opentelemetry.io/otel/unit
go get: module go.opentelemetry.io/otel@upgrade found (v1.0.0-RC1), but does not contain package go.opentelemetry.io/otel/unit

解决: 由于redis包的问题 版本更新 v8.10.0 -> v8.11.0
go get -u github.com/go-redis/redis/v8@v8.11.0
