What is the reason, how to solve it?
This repo uses Go modules feature and installation instructions clearly state it requires Go 1.13 or higher:
Install Go 1.13 or higher
From error messages it seems you have Go 1.10 which doesn't support modules (and likely also other features this repo depends on).
This error is caused by fact that prior modules support was added to Go in version 1.11; go tool was always looking up modules in $GOROOT and $GOPATH locations - and in your case it can't find them there.
Install Go 1.13 or higher to make the installation guide work. You can find recent enough packages in backport PPA or install latest from official tarball available here.
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 am trying to install the dependencies of my project with glidebut unfortunately it fails with the following message:

/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 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:

My GOROOT is /usr/lib/go and my GOPATH is /home/haapoo/go .
I know the question about gopath and goroot comes often but maybe anyone has an idea.
PS: I use goclipse

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.
