I am using cloud function to auto create some VM instance. Before, I was success in my use-case. You can view it here.Now, I want to update some line in metadata script. But when I save the code, it tell me some package I was import cannot find. Logs is
Build failed: src/cloudfunctions/function.go:9:2: cannot find package "google.golang.org/api/compute/v1" in any of:
/usr/local/go/src/google.golang.org/api/compute/v1 (from $GOROOT)
/workspace/src/google.golang.org/api/compute/v1 (from $GOPATH); Error ID: 2f5e35a0
But I was view document in https://pkg.go.dev/google.golang.org/api/compute/v1, usage example import like this import "google.golang.org/api/compute/v1", as same as me.
So, who can tell me what is $GOROOT and $GOPATH in cloud function, and how can I import this package.
Thanks in advance.
Run
go get -u -x google.golang.org/api/compute/v1
Then cd/open your directory in terminal then run
go mod init filename.go
then
go mod tidy
Also restart your IDE as that will need to update

I am new at Golang. I am learning about universal scope and importing variables from one file to another.
Conditions:
System: Windows 11 x64
IDE: VS code
Language: GoLang
According to the universal scope I should be able to import variables from one file to another easily. Primary file: "main.go" and secondary file ""uniscope.go
Importing from uniscope.go into main.go
If the files are kept in the same folder directory then I can easily import using command: "go run main.go uniscope.go"
This runs without any error but until this command I get the error in main.go, "undeclared name", that is still not the main issue.
When I move the uniscope.go to another folder and then I run "go run main.go uniscope.go", it doesn't work, which is understandable as directory has been changed. So then I copy the path and paste it in import which in turns resolves the previous error, change the command to "go run main.go" but it throws out a new one.
"main.go:6:7: illegal character U+0073 's' in escape sequence"
I am not sure how I am wrong here. The video I am learning from is: https://www.youtube.com/watch?v=vYD9XWi_Xw8&list=PLve39GJ2D71xX0Ham0WoPaYfl8oTzZfN6&index=5
He is using itelliJ but I don't think that should be an issue.
I have tried the mentioned above and also tried finding the exact error on google. Just found a similar question posted on some Portuguese forum with no answers.
main.go:
package main
import "hello/world"
func main() {
println(world.Value)
}
world/world.go:
package world
const Value = 1
and run:
go mod init hello
go run .
I'm trying to import a subdirectory I have in my project to my main file, but for some reason I get this error:
could not import ./service (no package for import ./service)
This is how I import:
import (
"os"
"service"
)
I also tried "service/app"
"./service/app"
"./service" nothing works, always the same error.
I'm trying to use the app.go file
This is the file structure:
Project Directory
-- main.go
-- service (directory)
-- app.go (file)
I tried to restart VS Code, tried to use go install/update tools, nothing works.
Also, this is my main func:
func main() {
a := &service.App()
a.Initialize(
os.Getenv("APP_DB_USERNAME"),
os.Getenv("APP_DB_PASSWORD"),
os.Getenv("APP_DB_NAME"),
)
a.Run(":8010")
}
&service.App() does not show a problem, but when I remove the "service" import, it does say
undeclared name: service
So I don't understand what the problem is.
This error sometime show on the "os" import too, I don't know why.
Golang doesn't support relative imports.
In modules, there finally is a name for the subdirectory. If the parent directory says "module m" then the subdirectory is imported as "m/subdir", no longer "./subdir".
So, in your case you should import service package as your_module_name/service.
I'm stuck on running the BeeGO app using "bee run" it says
The thing is I've already have setup properly my GOPATH to D:/Web Dev/GO/BeeGO/test-project/
and also routers path does exist and I've tried to manual build the file but it doesn't generate an .exe file.
Anyone knows how to fix this?
I'm using Windows 8.1 Pro (64-bit)
Thanks
GO expects the directory structure under $GOPATH in following ways as described in code organization:
$GOPATH/src <--- where your source code goes
/pkg
/bin
Instead of placing your source files directly under $GOPATH (D:/Web Dev/GO/BeeGO/test-project/ for your case), you want to move your code under $GOPATH/src.
D:/Web Dev/GO/BeeGO/test-project/src/main.go
D:/Web Dev/GO/BeeGO/test-project/src/quickstart/routers/routers.go
D:/Web Dev/GO/BeeGO/test-project/src/quickstart/controllers/controllers.go
import path should be always starting from $GOPATH/src. routers.go can be always imported as import "quickstart/routers" and controllers.go can be imported as import "quickstart/controllers".
That's not how you import a package.
The import path is relative to $GOPATH/src. use:
import "quickstart/routers"
Finally fixed the bug from the framework,
What I did:
in main.go import from
"D:/Web Dev/GO/BeeGO/test-project/quickstart/routers"
I changed it to _"../quickstart/routers" make sure to include _ this means to import the library even if it is not used,
Then in the routers/router.go I changed the import path
"D:/Web Dev/GO/BeeGO/test-project/quickstart/controllers" to "../controllers"
It seems BeeGO doesn't generate the template properly and caused the build to fail.
Another possiblity for this error, is when you copy-paste code from the internet,
and
import "quickstart/routers"
became
import "quickstart/routers "
due to bugs in some CMS/Blog systems (notice the space at the end before the closing quote...).
i'm currently try to install https://github.com/willnorris/imageproxy . I'm a newbie with go lang. So i installed first go, github and hg.
I tried a few things, clone the git repository, use go get, use go install, go build.
But nothing worked, it could download the files to the src direcotry, but didn't get the bin.
so has anybody an idea?
---edit---
with:
go get github.com/willnorris/imageproxy/cmd/imageproxy
i get:
[root#s17848415 go]# go get github.com/willnorris/imageproxy/cmd/imageproxy
# github.com/willnorris/imageproxy/cmd/imageproxy
src/github.com/willnorris/imageproxy/cmd/imageproxy/main.go:27: imported and not used: "github.com/sosedoff/imageproxy/proxy"
src/github.com/willnorris/imageproxy/cmd/imageproxy/main.go:60: undefined: imageproxy
--edit 2 ---
[root#s17848415 go]# go get github.com/willnorris/imageproxy/cmd/imageproxy
package willnorris.com/go/imageproxy: unrecognized import path "willnorris.com/go/imageproxy"
solution:
first:
go get github.com/willnorris/imageproxy/cmd/imageproxy
(downloads source)
second - change "vi github.com/willnorris/imageproxy/cmd/imageproxy"
last line
import (
"flag"
"fmt"
"log"
"net/http"
"strings"
"github.com/gregjones/httpcache"
"github.com/gregjones/httpcache/diskcache"
"github.com/willnorris/imageproxy"
)
last - again:
go get github.com/willnorris/imageproxy/cmd/imageproxy
I've updated the README file to include getting started instructions: https://github.com/willnorris/imageproxy#getting-started. Notably, you should go get as "willnorris.com/go/imageproxy", not "github.com/willnorris/imageproxy".
With halfdans advice, I was successfully able to use goinstall github.com/hoisie/web.go without any errors after installing git first. However, now when I try to compile the sample code given, go is not finding the web package. I get the error,
main.go:4: can't find import: web
On this code
package main
import (
"web"
)
func hello(val string) string { return "hello " + val }
func main() {
web.Get("/(.*)", hello)
web.Run("0.0.0.0:9999")
}
Is there something special I need to do in order for it to recognize the package? I found the package source at $GOROOT/src/pkg/github.com/hoisie/web.go/web. I tried github.com/hoisie/web.go/web as the import and it still did not like that.
If you install web.go through goinstall, you need to do:
import "github.com/hoisie/web.go"
Goinstall is still an experimental system. It would be nice if you didn't have to include the full path.
import web "github.com/hoisie/web.go"
