cannot find package "github.com/gorilla/mux" in any of:

Question

I use command go get github.com/gorilla/mux. I made http server using Golang, and I run this program :

package main

import (
    "fmt"
    "html"
    "log"
    "net/http"

    "github.com/gorilla/mux"
)

func main() {

    router := mux.NewRouter().StrictSlash(true)
    router.HandleFunc("/", Index)
    log.Fatal(http.ListenAndServe(":8080", router))
}

func Index(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))

But I conflict this error :

/usr/local/go/bin/go build -i [/Users/imac/go/src]
http.go:9:5: cannot find package "github.com/gorilla/mux" in any of:
    /usr/local/go/src/github.com/gorilla/mux (from $GOROOT)
    ($GOPATH not set)
Error: process exited with code 1.

The error message says `($GOPATH not set)`. – ivan.sim Jan 09 '17 at 03:36 — ivan.sim, Jan 09 '17 at 03:36
My `$GOPATH` is `/User/imac/go`. Is it problem? – Diana Jan 09 '17 at 03:38 — Diana, Jan 09 '17 at 03:38

Could you try this steps to debug it:

ls -l /usr/local/go/src/github.com | grep gorilla
cd $GOPATH

go list ... | grep gorilla
if you din't see gorilla in the above two command, then you need to install it: go get -v -u github.com/gorilla/mux

Please run this: export PATH=$PATH:$GOPATH/bin

How about running go run main.go ? is that working, if yes you should be able to do go build from your project path.

gorilla folder is not here. `/Users/imac/go/src/github.com` < in here... – Diana Jan 09 '17 at 03:36
You may need to install it. please do step 3. and let me know the output. – James Sapam Jan 09 '17 at 04:09
In 1 step, I see message `ls: /usr/local/go/src/github.com: No such file or directory`. In 2 step, I see path `github.com/gorilla/mux`. In 3 step, I install it but program is still show same error. – Diana Jan 09 '17 at 04:38
can u see by `go list ... | grep gorilla` – James Sapam Jan 09 '17 at 04:54
Yes. I can see path `github.com/gorilla/mux`. – Diana Jan 09 '17 at 05:00
export PATH=$PATH:$GOPATH/bin – James Sapam Jan 09 '17 at 05:05
i din't see $PATH in ur env var. – James Sapam Jan 09 '17 at 05:06
I have to store `export PATH=$PATH:$GOPATH/bin` in bash_profile? – Diana Jan 09 '17 at 05:40
just execute that command in cli and check if that works, if yes you can include into your .profile or .bash_profile – James Sapam Jan 09 '17 at 05:48
could you please paste the output of this cmd `echo $PATH $GOPATH` – James Sapam Jan 09 '17 at 06:15
`/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:/usr/local/go/bin:/Users/imac/go/bin:/Users/imac/go/bin /Users/imac/go` – Diana Jan 09 '17 at 06:16
Can u execute `go run main.go` from ur main script location ? – James Sapam Jan 09 '17 at 06:18
you can do `go build` or `go install` from the same path in terminal. Not sure about IDE part. – James Sapam Jan 09 '17 at 06:28
1. cd to the path where your main script is `cd /path_to_main/script` 2. `go build main.go` : this will create binaries into the same current directory. 3. If you want to install it `go install main.go`. – James Sapam Jan 09 '17 at 06:46

I wish this helpful. You may off the 'mod'.

$ export GO111MODULE=off

Great, this works for me. The reason it wasn't working for me is that gorilla was being downloaded in the mod folder and not the src folder as expected. – Rishabh Apr 23 '21 at 15:50
After struggling for 2-3 hrs, this one worked for me.By default pkgs are installed in mod instead of src. – dynamo Nov 01 '21 at 12:27

This works for me...

fire command > go mod init <your-directoryNane-where-main.go-exits>
fire command > go get github.com/gorilla/mux

after firing this both commands you will be able see 2 files :

go.mod
go.sum

finally, Close VS code and open again, the error will be resolved

go get github.com/gorilla/mux

Can you find `github.com/gorilla/mux` in $GOPATH/pkg subdirectory. If not. Try `go install github.com/gorilla/mux`. – No_20 Jan 09 '17 at 03:37
I try this but not working... `github.com/gorilla/mux` is in `$GOPATH/pkg/darwin_amd64`. – Diana Jan 09 '17 at 03:55

If you are using VS Code as your IDE and facing this problem:

VS Code uses $HOME/go as your default GOPATH - if you export another GOPATH you running into this trouble.

How to solve:

Use the VS Code internal terminal and navigate to your project folder: cd prjectFolder. Type go env and check if the GOPATH entry is the same as you get when you use cmd+t and then >Go: Current GOPATH
If it doesn't fit, add in your user settings: "go.gopath": "/some/path" where /some/path is the same path you export in you shell, zsh and so on.

Hope this helps.

I try to remove github.com/gorilla and github.com/peterbourgon directory, then, retry: make, it works.

Try go build /Users/imac/go/src/project

because I see you try to use go build under /Users/imac/go/src

Maybe this can help other users running in Windows. In my case I had to create two symlinks:

 1. run cmd as administrator  
 2. cd %gopath%  
 3. mklink /D src pkg\mod  
this creates a symlink between src and pkg\mod
 4. cd src\github.com\gorilla

Here you'll notice that the mux package might be listed as mux@v1.8.0

 5. mklink /D mux mux@v1.8.0

With this, go will be able to find github.com/gorilla/mux under %gopath%\src\github.com\gorilla\mux

Finally, you have to set GO111Module to off set GO111Module=off

and now you can build your app:

go build app.go

cannot find package "github.com/gorilla/mux" in any of:
