Golang 1.11beta2引入了對Modules的實驗支持。我無法從go模塊中導入特定的程序包。這是構(gòu)建應(yīng)用程序時的錯誤：$ go installgo: downloading github.com/udhos/modhello/modlib/lib v1.0.0go: finding github.com/udhos/modhello latestgo: import "github.com/udhos/modhello/modapp" ->    import "github.com/udhos/modhello/modlib/lib": cannot find module providing package github.com/udhos/modhello/modlib/lib為什么上面顯示的導入失?。窟@是來自模塊'modlib'的軟件包'lib'：# repo: modhello# module: modlib# package: lib$ cat modhello/modlib/lib/modlib.gopackage libfunc Sum(a, b int) int {    return a + b}$ cat modhello/modlib/go.modmodule github.com/udhos/modhello/modlib這是應(yīng)用程序“ modapp”：$ cat modhello/modapp/main.gopackage mainimport (        "log"        "github.com/udhos/modhello/modlib/lib")func main() {        run(1, 2)}func run(a, b int) {        log.Printf("Sum(%d,%d) = %d", a, b, lib.Sum(a, b))}$ cat modhello/modapp/go.modmodule github.com/udhos/modhello/modapprequire github.com/udhos/modhello/modlib v1.0.0git存儲庫標記為“ modlib / v1.0.0”。這就是發(fā)布模塊版本的方式。轉(zhuǎn)到版本：$ go versiongo version go1.11beta2 linux/amd64$ git --versiongit version 2.18.0我還在golang-nuts上發(fā)布了這個疑問：在一個git repo中托管兩個不同的模塊？
