undefined: otel.Meter or cannot find package "go.opentelemetry.io/otel/api/trace"

[vmihailenco]

To fix cannot find package "go.opentelemetry.io/otel/api/trace" or undefined: otel.Meter:

1. Make sure to initialize a Go module: go mod init github.com/my/repo

2. Make sure to use correct import path with v8 in the end: go get github.com/go-redis/redis/v8

For example:

mkdir /tmp/redis-test
cd /tmp/redis-test
go mod init redis-test
go get github.com/go-redis/redis/v8

The root cause

The error is not caused by OpenTelemetry. OpenTelemetry is just the first module Go tries to install. And the error will not go away until you start using Go modules properly.

The presence of $GOROOT or $GOPATH in error messages indicates that you are NOT using Go modules.

go get -u go.opentelemetry.io/otel/apils

I got this error when initializing the module and downloading all dependencies:
go get go.opentelemetry.io/otel/apils: module go.opentelemetry.io/otel@upgrade found (v0.13.0), but does not contain package go.opentelemetry.io/otel/apils

@vmihailenco you don't need to install go.opentelemetry.io/otel/apils. And you have typo in the name.

Thanks for answering in such a short time... I appreciate that
just to make my previous post clear, the typo was a copy paste issue for this post (my bad). The thing is that go says
go get go.opentelemetry.io/otel/api: module go.opentelemetry.io/otel@upgrade found (v0.13.0), but does not contain package go.opentelemetry.io/otel/api
the same goes with the /otel/api/trace

[vmihailenco]

I don't understand what you are trying to do. To install go-redis you don't need opentelemetry:

mkdir /tmp/redis-test
cd /tmp/redis-test
go mod init redis-test
go get github.com/go-redis/redis/v8

Sorry if ai'm not clear:
I've been using go-redis for months now. yesterday I tried to build my code and the compiler showed me the error I sent on my initial post. Go keeps trying to get the package go.opentelemetry.io/otel/api/trace. If I do a go build, the error is:
/home/gonzalo/golib/src/github.com/go-redis/redis/internal/util.go:10:2: cannot find package "go.opentelemetry.io/otel/api/trace" in any of:
/usr/local/go/src/go.opentelemetry.io/otel/api/trace (from $GOROOT)
/home/gonzalo/golib/src/go.opentelemetry.io/otel/api/trace (from $GOPATH)
/home/gonzalo/go/src/go.opentelemetry.io/otel/api/trace

Yes, I also get this error when installing packages.
I noticed that the go.opentelemetry.io package was recently updated (Move trace api package into ʻotel` (# 1229)
) and now there is no go.opentelemetry.io/otel/api/trace. Some of your code files have links to /api/trace (span trace.Span), but now they are gone.
The update will be like this -
import "go.opentelemetry.io/otel"
func (ctx context.Context, span otel.Span)
I'm sorry if I'm wrong

[gonzalochief]

Actually,, your suggestion worked! if you need the fixed code while the fix gets implemented in the oficial repository, i can share it...
