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

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
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 have get go1.11.5 installed by downloading precompiled binary package directly on my ubuntu18.04. Now i want to install go1.12 by building from source, so i follow with Installing Go from source.
I set GOROOT_BOOTSTRAP=~/goroot_bootstrap
$ mkdir -p ~/goroot_bootstrap/bin
$ cp /usr/local/go/bin/go ~/goroot_bootstrap/bin/
$ echo "export GOROOT_BOOTSTRAP=~/goroot_bootstrap" >> ~/.bashrc
$ source ~/.bashrc
Then, get source
$ git clone -b release-branch.go1.12 https://github.com/golang/go.git ~/github.com/golang/go
Build
$ cd ~/github.com/golang/go/src
$ ./all.bash
It failed, and tips:
Building Go cmd/dist using /home/pi/goroot_bootstrap.
cmd/dist/imports.go:12.2: cannot find package "bufio" in any of:
/home/pi/goroot_bootstrap/src/bufio (from $GOROOT)
/home/pi/go/src/bufio (from $GOPATH)
...
But if i set GOROOT_BOOTSTRAP=/usr/local/go, it will success.
Then, i read source code at src/make.bash.
166 rm -f cmd/dist/dist
167 GOROOT="$GOROOT_BOOTSTRAP" GOOS="" GOARCH="" GO111MODULE=off "$GOROOT_BOOTSTRAP/bin/go" build -o cmd/dist/dist ./cmd/dist
The bootstrap toolchains build cmd/dist with GOROOT="$GOROOT_BOOTSTRAP" at line 167.
If i have GOROOT_BOOTSTRAP=/usr/local/go set and success, which means building still depending old package such as bufio.
So, why it failed when setting GOROOT_BOOTSTRAP=~/goroot_bootstrap?
Do building depends old package if setting GOROOT_BOOTSTRAP=/usr/local/go?
Which one is the right method to install from source?
Any help will be grateful.
I am trying to install the dependencies of my project with glidebut unfortunately it fails with the following message:
main.go:7:2: cannot find package "github.com/arschles/go-in-5-minutes/episode13/models" in any of:
/Users/theo/go-workspace/src/github.com/thitami/go-in-5-minutes/episode13/vendor/github.com/arschles/go-in-5-minutes/episode13/models (vendor tree)
/usr/local/Cellar/go/1.8.3/libexec/src/github.com/arschles/go-in-5-minutes/episode13/models (from $GOROOT)
/Users/theo/go-workspace/src/github.com/arschles/go-in-5-minutes/episode13/models (from $GOPATH)
Running a go env, this is my env variables of interest:
GOPATH="/Users/theo/go-workspace"
GOROOT="/usr/local/Cellar/go/1.8.3/libexec"
Please be advised that I am zsh and I am exporting the GOPATH inside the .zshrc file like this:
export GOPATH=HOME/go-workspace
Any ideas are appreciated
* UPDATE *
As requested this is the piece of code with the call to the models package:
import (
"database/sql"
"log"
"github.com/arschles/go-in-5-minutes/episode13/models"
_ "github.com/mxk/go-sqlite/sqlite3"
)
You can only set the gopath once and you'll have to reset it every time you change packages. Think of it as a virtualenv. One way around it is to install the packages global or by using something like gvm
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.
