- go版本需要>=1.11,将项目移到GOPATH以外
或者显式开启go mod 模式export GO111MODULE=on
- 首次使用在项目根目录执行
go mod github.xsky.com/user_name/your_module
该命令会生成go.mod 文件，里面是将来项目的具体依赖，依赖一般会在go build/go test等命令执行时候自动拉取。
比如我一个项目build 完成后式这样的
module github.xsky.com/xsky/xsky-csi

- 这些依赖是指定了版本，存放在
$GOPATH/pkg/mod/*
比如~/Documents/workspace/gopath/pkg/mod/k8s.io/[email protected]
和vendor不一样，这些是包可以复用的，只要go.mod里面的版本对应得上即可。
然后这里build的时候遇到了一个问题
../../workspace/gopath/pkg/mod/k8s.io/[email protected]/pkg/features/kube_features.go:52:2: undefined: feature.DefaultMutableFeatureGate
通过切换不同版本也是类似的错误
# k8s.io/kubernetes/pkg/features
../../workspace/gopath/pkg/mod/k8s.io/[email protected]/pkg/features/kube_features.go:399:32: feature.DefaultFeatureGate.Add undefined (type feature.FeatureGate has no field or method Add)
从错误上看是这样的：
获取到的依赖[email protected]内容
实际GitHub上的源码：
就是说实际依赖是错误的，源码都已经更新了
到golang仓库下提了issue
得到回复
The problem here is some sort of version skew between the various kubernetes modules. (See https://github.com/kubernetes/apiextensions-apiserver#compatibility.)
解决办法：
显式下载最新的go module
go get -v -m k8s.io/[email protected] k8s.io/[email protected] k8s.io/[email protected] k8s.io/[email protected]
然后把go.mod里的这几个依赖版本写上刚才获取的这个几个，或者直接删除掉，然后执行下面整理不必要的包
go mod tidy
然后全部build一次
go build ./... or go build all 此时应该已经构建通过了
另外几个很有用的命令
go clean -modcache 清理下载的go 模块缓存
go list -m -json all 查看build的时候最终使用的模块详情
❯ go list -m -json all
