i receive the following error message on command: go env -w GO111MODULE=off; go get -v github.com/prometheus/client_golang/prometheus

i have tried it also as recommended from go but this also not work:

#15 2.146 + go env -w GO111MODULE=on
#15 2.149 + go install github.com/prometheus/client_golang/prometheus@latest
#15 2.226 go: downloading github.com/prometheus/client_golang v1.13.0
#15 2.275 go: github.com/prometheus/client_golang/prometheus@latest (in github.com/prometheus/client_golang@v1.13.0):
#15 2.275   The go.mod file for the module providing named packages contains one or
#15 2.275   more exclude directives. It must not contain directives that would cause
#15 2.275   it to be interpreted differently than if it were the main module.

and just in case you came again with this solution: https://github.com/prometheus/client_golang/issues/1154

this doesn`t help:

root@866a2fe8fad6:/go/src/camunda-engine-prometheus-exporter# GO111MODULE=off go get -v github.com/prometheus/client_golang
github.com/prometheus/client_golang (download)

i have the same issue.

@kakkoyun any update on this ?

[reimgun]

it seems to be working with the following commands: go env -w GO111MODULE=on git clone https://github.com/prometheus/client_golang cd /go/src/client_golang cp main.go . go build -a -installsuffix cgo -o /app/publish .

[kakkoyun]

@reimgun Sorry, I dropped the ball on this. I'll keep the tab open to take care of this. Thanks for further investigation.

[mwiede]

I came across which might be the root cause https://github.com/prometheus/common/issues/381#issuecomment-1290267963

[keremgocen]

hey @reimgun, manually changing your dependency version for github.com/matttproud/golang_protobuf_extensions from v1.0.3 => v.1.0.2 seems to be working for me when using GO111MODULE=on. Not quite sure how you'd do the same when not using modules though (maybe someone else can help on that, manually change what you have installed at your GOPATH etc).

go build . fails with the default/latest v1.0.3 and I can repro the error about *io_prometheus_client.MetricFamily does not implement protoreflect.ProtoMessage (missing ProtoReflect method). Looks like a dependency issue.

(ps: this also looks related https://github.com/golang/protobuf/issues/1133#issuecomment-629376146 cc: @kakkoyun)

manually changing your dependency version for github.com/matttproud/golang_protobuf_extensions from v1.0.3 => v.1.0.2 seems to be working for me when using GO111MODULE=on.

I am using go 1.20.3 could you please share the steps you followed to fix this issue?

in go.mod of v1.5.0 i have changed

require (
...
        github.com/matttproud/golang_protobuf_extensions v1.0.4 // indirect

to

require (
...
        github.com/matttproud/golang_protobuf_extensions v1.0.2 // indirect

a) when i use go build ,i get this -

[puneets@den-l-081]~/client_golang-1.15.0>ls

go build .
no Go files in /home/puneets/27042023/nodeexporters/lsfnodeexporter/client_golang-1.15.0

b) when i run make i get following error -
