Unable to install docker-credential-ecr-login using go install

As developer trying to use docker-credential-ecr-login, I tried installing using go install

go install github.com/awslabs/amazon-ecr-credential-helper/ecr-login/cli/[email protected]

It results in the following error,

go: github.com/awslabs/amazon-ecr-credential-helper/ecr-login/cli/[email protected]: module github.com/awslabs/[email protected] found, but does not contain package github.com/awslabs/amazon-ecr-credential-helper/ecr-login/cli/docker-credential-ecr-login

If I do go install github.com/awslabs/amazon-ecr-credential-helper/ecr-login/cli/docker-credential-ecr-login@latest it works. but I need to pin to a version of the binary.

Any clues?

It is my understanding that you have to give the directory that contains go.mod:

So, for instance:

go install github.com/santhosh-tekuri/jsonschema/cmd/[email protected]

works.

However,

go install "github.com/awslabs/amazon-ecr-credential-helper/[email protected]

does not work, either:

go: github.com/awslabs/amazon-ecr-credential-helper/[email protected]: module github.com/awslabs/[email protected] found, but does not contain package github.com/awslabs/amazon-ecr-credential-helper/ecr-login

This is with golang 1.20.6.

My suspicion is that go.mod and main.go need to be located in the same directory, but I certainly don't fully understand how go install resolves its arguments; the help output is confusing.

In the meantime, I do this as part of my Docker build:

# renovate: datasource=github-tags depName=awslabs/amazon-ecr-credential-helper versioning=semver
ENV AWS_ECR_CRED_HELPER_VERSION="v0.7.1"

RUN apk add --no-cache wget \
 && wget -nv -O /go/bin/docker-credential-ecr-login \
      https://amazon-ecr-credential-helper-releases.s3.us-east-2.amazonaws.com/${AWS_ECR_CRED_HELPER_VERSION#v}/linux-amd64/docker-credential-ecr-login \
 && chmod +x /go/bin/docker-credential-ecr-login

Issue persists with golang 1.21.5.
