I have installed a package in windows using
go get github.com/couchbaselabs/go-couchbase
No message apprear after installation.
Then I tried to include in Go
import (
"github.com/couchbaselabs/go-couchbase"
)
However,when I build, I got the message
main.go:7:2: cannot find package "github.com/couchbaselabs/go-couchbase" in any of:
c:\go\src\pkg\github.com\couchbaselabs\go-couchbase (from $GOROOT)
C:\Go\src\Chaatz\src\github.com\couchbaselabs\go-couchbase (from $GOPATH)
C:\Go\src\github.com\couchbaselabs\go-couchbase
Am I miss something, or the package is installed to other path?
For example,
>set gopath
GOPATH=C:\gopath
>go get -v github.com/couchbaselabs/go-couchbase

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

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

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.
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"
)
how to verify if fips mode is enabled for binary in golang dev boring crypto branch ?
I dont see an easy way apart from internal golang tests
From this file:
https://go.googlesource.com/go/+/dev.boringcrypto/src/crypto/tls/fipsonly/fipsonly.go
// Package fipsonly restricts all TLS configuration to FIPS-approved settings.
//
// The effect is triggered by importing the package anywhere in a program, as in:
//
// import _ "crypto/tls/fipsonly"
//
// This package only exists in the dev.boringcrypto branch of Go.
By including that import statement in your program, it will only compile if you're using the dev.boringcrypto branch.
Here's a test main.go:
package main
import (
"fmt"
_ "crypto/tls/fipsonly"
)
func main() {
fmt.Println("Hello FIPS")
}
Using the dev.boringcrypto branch of Go:
$ go version
go version go1.12.9b4 linux/amd64
$ go run main.go
Hello FIPS
Using the normal release of Go:
$ go version
go version go1.12.9 darwin/amd64
$ go run main.go
main.go:4:2: cannot find package "crypto/tls/fipsonly" in any of:
/Users/ray/.gimme/versions/go1.12.9.darwin.amd64/src/crypto/tls/fipsonly (from $GOROOT)
/Users/ray/go/src/crypto/tls/fipsonly (from $GOPATH)
I have problems with importing a package. I want to import the "golang.org/x/tools/cmd/oracle" and the "golang.org/x/tools/oracle" package.
Which is the correct way to import these packages?
This the way I try to import the packages:
package main
import (
"fmt"
"strings"
"os"
"os/exec"
"golang.org/x/tools/oracle"
"golang.org/x/tools/cmd/oracle"
)
The both last imports leads to the following problem:

Have you run go get golang.org/x/tools/oracle and go get golang.org/x/tools/cmd/oracle ? This should be run after $GOPATH is properly set.
Never ever set GOROOT. (Unless you know what you are doing). Setting it is not needed.
As you cannot import golang.org/x/tools/cmd/oracle as this is a main package. At least you cannot do this the easy way and you should not anyway (except if you want to test the imported main package).
Importing is not magic, you'll have to download the package before using it. Use go get as others have mentioned.
Build on the command line to be sure what you are doing and how you are doing it (IDEs tend to blur things here).
If you need to import different packages of the same name in Golang, this is the way(just name it):
import (
"text/template"
ht "html/template"
)
but in case of "golang.org/x/tools/cmd/oracle"
it is not a package , it has just main.go and you need to build/install it. it is a command line tool:
Run 'oracle -help' for more information.
Go source code oracle.
Usage: oracle [<flag> ...] <mode> <args> ...
The -format flag controls the output format:
plain an editor-friendly format in which every line of output
is of the form "pos: text", where pos is "-" if unknown.
json structured data in JSON syntax.
xml structured data in XML syntax.
oracle is a source analysis command line tool, you can't import it. Use the following command to get it:
go get golang.org/x/tools/cmd/oracle
This will create an executable named oracle in your $GOPATH/bin directory.
Visit http://golang.org/s/oracle-user-manual for the complete oracle documentation.
