GO111MODULE=on (加载模块要求时出错)

Question

go get -u github.com/junegunn/fzf运行良好，但希望测试开发分支，如下所示：

gert@gert ~/ GO111MODULE=on go get -u github.com/junegunn/fzf@devel
go: finding github.com/junegunn/fzf devel
go: finding golang.org/x/crypto latest
go: finding github.com/smartystreets/assertions latest
go: finding github.com/gopherjs/gopherjs latest
go: finding github.com/smartystreets/goconvey latest
go: finding github.com/gopherjs/gopherjs v0.0.0-20181017120253-0766667cb4d1
go: finding golang.org/x/sys latest
go: finding golang.org/x/tools v0.0.0-20190328211700-ab21143f2384
go: gopkg.in/DATA-DOG/go-sqlmock.v1@v1.3.3: go.mod has non-....v1 module path "github.com/DATA-DOG/go-sqlmock" at revision v1.3.3
go get: error loading module requirements

不知道这是怎么回事？如果我这样做，也会得到同样的结果

GO111MODULE=on go get -u github.com/junegunn/fzf

Answer 1

fzf所需的Package github.com/gdamore/tcell存在gopkg.in/DATA-DOG/go-sqlmock.v1依赖。在go-sqlmock的1.3.3版本中，他们开始使用没有版本后缀的go模块，现在显式的版本指示不再有效。

go get gopkg.in/DATA-DOG/go-sqlmock.v1
go: gopkg.in/DATA-DOG/go-sqlmock.v1@v1.3.3: go.mod has non-....v1 module path "github.com/DATA-DOG/go-sqlmock" at revision v1.3.3
go: error loading module requirements

如果您希望在不更新依赖项的情况下处理devel包，请使用不带-u标志的go get github.com/junegunn/fzf。
