Hi I installed golang grpc in my vscode project with some go get commands,
go get -u google.golang.org/protobuf/cmd/protoc-gen-go
go install google.golang.org/protobuf/cmd/protoc-gen-go
go get -u google.golang.org/grpc/cmd/protoc-gen-go-grpc
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc
from https://stackoverflow.com/a/62872353/4159198
my project builds/runs inside vscode and on the command line but autocomplete gives me an error,
could not import google.golang.org/grpc (cannot find package "google.golang.org/grpc" in any of
/usr/local/go/src/google.golang.org/grpc (from $GOROOT)
/home/john/go/src/google.golang.org/grpc (from $GOPATH))
Find from my home directory:
find * -iname google.golang.org
go/src/google.golang.org
go/pkg/mod/google.golang.org
go/pkg/mod/cache/download/google.golang.org
go/pkg/mod/cache/download/sumdb/sum.golang.org/lookup/google.golang.org
My .profile bottom,
export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:~/go
export GOPATH=/home/john/go
export PATH=$PATH:$GOPATH/bin
I tried copying the source from pkg to src directory.
Try to launch go mod init on every program you want to compile.
If there was packages to imported and it missing, there will be a lightbulb icon that you can click on to automatically go get the packages you want
On your go.mod will there written
google.golang.org/genproto v0.0.0-20200526211855-cb27e3aa2013 // indirect
google.golang.org/protobuf v1.25.0 // indirect

could not import github.com/gorilla/mux (cannot find package "github.com/gorilla/mux" in any of
C:\Program Files\Go\src\github.com\gorilla\mux (from $GOROOT)
C:\Users\lenovo\go\src\github.com\gorilla\mux (from $GOPATH))compilerBrokenImport
I have installed gorilla mux using the cmd "go get github.com/gorilla/mux" but I'm getting this error.enter image description here
Looks like you didn't run "go mod init" before the "go get".
In cmd, try this:
cd [the dir of your source code]
go mod init
go get github.com/gorilla/mux
For more information run:
go help mod
Afterwards, you might also need to restart VS Code.
A Go language tutorial uses the "quote" package to get familiar quotes. When I give the command "go get -v rsc.io/quote", I get the message
code in directory.../github/hello/src/rsc.io/quote/v3 expects import "rsc.io/quote"
So I went there and looked at the code. It has an import statement:
import "rsc.io/quote/v3"
So I thought maybe I had the wrong version of quote. Accordingly, I tried "go get -v rsc.io/quite/v3" THis produces the message:
code in directory .../rsc.io/quote/v3 expects import "rsc.io/quote."
This seems circular: asking without a version number produces a requirement for a versioned package, but trying to get a versioned package produces a requirement without a version number.
If you continue the tutorial to the end you will see that the addition of a go module, and the subsequent initialisation, will resolve your issue. The .mod file will pull in the required dependencies.
Can you try
go get -v rsc.io/quote
get "rsc.io/quote": found meta tag get.metaImport{Prefix:"rsc.io/quote", VCS:"git", RepoRoot:"https://github.com/rsc/quote"} at //rsc.io/quote?go-get=1

More about go get vs go install. What is the difference between go get and go install?
Can you please check your GO env path settings:
export GOPATH=$HOME/github/<your_workspace_name>
export GOBIN=$GOPATH/bin
export GOROOT=/usr/local/go
export PATH=$PATH:/usr/local/bin:/usr/local/go/bin:$GOPATH/bin
Here is a good source for setting up workspace:

As #MartinBennett mentioned, it's already mentioned in the tutorial but may be not so clear.
Once you add import "rsc.io/quote" in your hello.go file, you will need to run these commands in your terminal:
1-
go mod init hello
2-
go run hello.go
I have been trying to build a module on Go v1.13 with dependencies on github.com/aws/aws-lambda-go and github.com/aws/aws-sdk-go which fail on the two imports:
"github.com/aws/aws-sdk-go/aws/service/s3"
"github.com/aws/aws-sdk-go/aws/service/s3/s3manager"
The stderr is as follows for GOOS=linux GOARCH=amd64 go build -o dist/api ./api where the api directory contains my module definition:
api/main.go:11:2: cannot find package "github.com/aws/aws-sdk-go/aws/service/s3" in any of:
/usr/local/go/src/github.com/aws/aws-sdk-go/aws/service/s3 (from $GOROOT)
/u/go/src/github.com/aws/aws-sdk-go/aws/service/s3 (from $GOPATH)
api/main.go:12:2: cannot find package "github.com/aws/aws-sdk-go/aws/service/s3/s3manager" in any of:
/usr/local/go/src/github.com/aws/aws-sdk-go/aws/service/s3/s3manager (from $GOROOT)
/u/go/src/github.com/aws/aws-sdk-go/aws/service/s3/s3manager (from $GOPATH)
Honestly, I have no clue why this is happening and any inputs would be appreciated.
Already tried using go get to ensure that the dependencies have been pulled:
$ go get github.com/aws/aws-sdk-go
and the requested import paths are present under $GOPATH/src/github.com/aws/aws-sdk/go/aws/service/s3 and $GOPATH/src/github.com/aws/aws-sdk/go/aws/service/s3/s3manager
Also, tried clearing the cache using go clean --cache --modcache whilst removing previously pulled modules.
On closer inspection, something that I completely overlooked, the import path is /u/go/src/github.com/aws/aws-sdk-go/aws/service/s3 instead of /u/go/src/github.com/aws/aws-sdk-go/service/s3 with the former having an additional aws subpath inside aws-sdk-go.
Just realized the copy/paste error I had made in the code.
import (
"github.com/aws/aws-sdk-go/aws/service/s3"
"github.com/aws/aws-sdk-go/aws/service/s3/s3manager"
)
instead of
import (
"github.com/aws/aws-sdk-go/service/s3"
"github.com/aws/aws-sdk-go/service/s3/s3manager"
)
I'm trying to install the context package in golang, which I did like this :
go get golang.org/x/net/context
But when I do an import "context", I still get the following error :
cannot find package "context" in any of:
/usr/lib/go-1.6/src/context (from $GOROOT)
/home/saurabh/work/src/context (from $GOPATH)
Can anyone suggest how to install this package ? I'm currently using version go1.6.2.
change import "context" to import "golang.org/x/net/context".
but after go 1.7 you can use import "context", as it had become a standard library.
Go 1.7 moves the golang.org/x/net/context package into the standard library as context.
see 1.7 release notes: https://golang.org/doc/go1.7#context
I faced similar issue , below are the steps to fix:
Download the latest version https://golang.org/doc/install?download=go1.9.2.linux-arm64.tar.gz
Extract the tar to /usr/local/ .
Use Command ->
tar -xzvf go1.9.2.linux-arm64.tar.gz -C /usr/local
Replace the symlink pointing to go:
sudo rm /usr/bin/go
sudo ln -s /usr/local/go/bin/go /usr/bin/go

I'm just getting started with the Go programming language and installed Go using the Windows installer from the website. I tested installation by using go run hello.go and that works. The problem comes when I try to build my first program:
$ echo $GOROOT
C:\Go\
$ echo $GOPATH
/cygdrive/c/Users/Paul/Documents/Home/go
mkdir -p $GOPATH/src/hello
Inside that directory I have a simple hello.go program:
package main
import "fmt"
func main() {
fmt.Printf("Hello, world.\n")
}
The problem comes when I try to build and install:
$ go install hello
can't load package: package hello: cannot find package "hello" in any of:
C:\Go\src\hello (from $GOROOT)
\cygdrive\c\Users\Paul\Documents\Home\go\src\hello (from $GOPATH)
GOPATH environment variable must contain valid path.
\cygdrive\c\Users\Paul\Documents\Home\go\src\hello is not a valid path on Windows.
Try setting GOPATH=c:\Users\Paul\Documents\Home\go instead.
