go.mod 在修订时有 post-v0 模块路径 "git.example.com/owner/repo/v3"...？

Question

在更新 go.mod 以具有 /v3 后缀 ( https://github.com/golang/go/wiki/Modules#releasing-modules-v2-or-higher ) 之前，我的同事推送了一个标签 v3.0.1。我更新了模块路径 (go.mod) 和所有导入路径 (*.go) 来修复它，标记为 v3.0.2。

现在的问题是:

go get -v git.example.com/owner/repo@v3.0.2
go: finding git.example.com/owner/repo v3.0.2
go: git.example.com/owner/repo@v0.0.0-20190722053407-d85c4f69ad17: go.mod has post-v0 module path "git.example.com/owner/repo/v3" at revision 
d85c4f69ad17

找到这个:go build keeps complaining that: go.mod has post-v0 module path

所以，我删除了 v3.0.0 和 v3.0.1 标签，将其指向最新的提交，重新推送但问题仍然存在。

我注意到 go.mod 仍然引用旧版本作为间接依赖:

require (
    git.example.com/owner.repo v0.1.2 // indirect

即使我将其更改为 /v3 v3.0.2，它也会自动恢复为 v0.1.12。

为什么？

我错过了什么吗？

rm go.*
go mod init git.example.com/dependent/project
go mod tidy

和 go.mod 现在已正确更新:

require (
-       git.example.com/owner/repo v0.1.2
+       git.example.com/owner/repo/v3 v3.0.2

但是 go get -v git.example.com/owner/repo@v3.0.2 仍然返回错误:

go: finding git.example.com/owner/repo v3.0.2
go: git.example.com/owner/repo@v0.0.0-20190722053407-d85c4f69ad17: go.mod has post-v0 module path "git.example.com/owner/repo/v3" at revision 
d85c4f69ad17

(d85c4f69ad17 是 master 中的最新提交)

我注意到go.sum中同时存在v0.1.2和v3.0.2:

git.example.com/owner/repo v0.1.2 h1:mCGJEmyrFDTCGkRfUIORpqdrNkSONQ6K+AcTNgxqveY=
git.example.com/owner/repo v0.1.2/go.mod h1:FfUKnyPrARCtAXQZ3BQVJI7h2eJ0UpQBMLg4bNs4Kdc=
git.example.com/owner/repo/v3 v3.0.2 h1:mJtDKLeiP8vMRSZo08i/k/KDbIoZTlKW2aWu7DUBvMM=
git.example.com/owner/repo/v3 v3.0.2/go.mod h1:64LE0ts0Lk9InIQyhPYGmnxs6LZIl6H4Iorl1EXfqxo=

Answer 1

请注意我的go get命令:

go get -v git.example.com/owner/repo@v3.0.2

应该是:

go get -v git.example.com/owner/repo/v3@v3.0.2
