How to fix Go 1.11 module unknown import path, cannot find module providing package?

Question

I am building a Go 1.11 Standard App Engine Service.

It's not under GOPATH , so I ran go mod init and go mod tidy .

I am able to build a simple web service using go build , and deploy and test using gcloud app deploy .

I am now trying to add gPubSub code to my service following this code example .

This adds the following imports: "context" , "cloud.google.com/go/pubsub" .

When I run go build , I get:

../../../../go/pkg/mod/golang.org/x/net@v0.0.0-20181217023233-e147a9138326/idna/idna.go:23:2: unknown import path "golang.org/x/text/secure/bidirule": cannot find module providing package golang.org/x/text/secure/bidirule
../../../../go/pkg/mod/golang.org/x/net@v0.0.0-20181217023233-e147a9138326/idna/idna.go:24:2: unknown import path "golang.org/x/text/unicode/bidi": cannot find module providing package golang.org/x/text/unicode/bidi
../../../../go/pkg/mod/golang.org/x/net@v0.0.0-20181217023233-e147a9138326/idna/idna.go:25:2: unknown import path "golang.org/x/text/unicode/norm": cannot find module providing package golang.org/x/text/unicode/norm

When I run go get -u all , I get "no Go files in"

go build golang.org/x/text/secure/bidirule: no Go files in
go build golang.org/x/text/unicode/bidi: no Go files in
go build golang.org/x/text/unicode/norm: no Go files in

cat go.mod shows me the following: ```

module github.com/XXX/YYY

require (
    cloud.google.com/go v0.34.0
    github.com/googleapis/gax-go v2.0.2+incompatible // indirect
    go.opencensus.io v0.18.0 // indirect

    google.golang.org/grpc v1.17.0 // indirect
)

```

go list . shows me the following:

go: finding golang.org/x/text/unicode/bidi latest
go: finding golang.org/x/text/secure/bidirule latest
go: finding golang.org/x/text/unicode/norm latest
go: finding golang.org/x/text/unicode latest
go: finding golang.org/x/text/secure latest
github.com/XXX/YYY/ZZZ (our project)

This seems to be some transient dependency.

When I deploy using gcloud app deploy , my service does successfully build and on execution, publishes to the pubsub topic, so this is a local problem.

How do I diagnose and fix this local dev environment problem?
