英文:
go no required module provides package mux error
问题
所以我有以下的代码，
package main
import (
"github.com/gorilla/mux"
)
func main() {
router := mux.NewRouter()
}
当我运行go run .时，它会给出以下错误信息：
binapi.go:4:2: no required module provides package github.com/gorilla/mux; to add it: go get github.com/gorilla/mux
我该如何解决这个错误？我已经以各种方式运行了go get github.com/gorilla/mux命令，并确保它已安装。我以前找到过一篇帖子，但它给出的命令没有起作用。命令是go env -w GO111MODULE=auto，但它没有解决问题。
这是我的go env：
GO111MODULE="auto"
GOARCH="amd64"
GOBIN=""
GOCACHE="/Users/ProfMonkey07/Library/Caches/go-build"
GOENV="/Users/ProfMonkey07/Library/Application Support/go/env"

英文:
so I have the following code,
package main
import (
"github.com/gorilla/mux"
)
func main() {
router := mux.NewRouter()
}
when I do go run ., it gives the following error
binapi.go:4:2: no required module provides package github.com/gorilla/mux; to add it: go get github.com/gorilla/mux, how do I fix this error? I have run the go get github.com/gorilla/mux command in every way possible and im sure it is installed. I found a post a while back but the command it gave didn't work. The command was go env -w GO111MODULE=auto but it didnt solve the issue.
here is the go env
GO111MODULE="auto"

看起来你的项目根目录下没有go.mod文件。首先运行go mod init <name>命令。
然后当你运行go mod tidy命令时，它会将"github.com/gorilla/mux"依赖项添加到所需模块列表中，或者你可以使用指定的命令go get github.com/gorilla/mux手动添加它。
这种行为在go1.16中已经发生了变化。在此之前，它会自动为你添加依赖项。
如果你使用版本控制系统，请确保提交go.mod和go.sum文件。
英文:
Sounds like you do not have a go.mod file in the root of your project. Run go mod init <name> first.
Then when you run a go mod tidy it will add the "github.com/gorilla/mux"-dependency into the list of required modules, or manually add it with the stated go get github.com/gorilla/mux.
This behavior has changed in go1.16. Before it would automatically add the dependencies for you.
Make sure to commit both the go.mod and go.sum files should you use a VCS.
