[SOLVED] How do you install subcommands?

How do you install subcommands?

I am getting the following error message in Go v. 1.15.8 darwin/amd64

main.go:8:2: cannot find package "github.com/google/subcommands" in any of:
/usr/local/go/src/github.com/google/subcommands (from $GOROOT)
/Users/user1/go/src/github.com/google/subcommands (from $GOPATH)

The code in main.go looks like:

package main

import (
        "flag"
        "context"
        "os"

        "github.com/google/subcommands"
)

I know subcommands is located here: https://github.com/google/subcommands with the git repo here: https://github.com/google/subcommands.git

But how do I install it?

When I do:

go get github.com/google/subcommands

I get the following error message:

# cd .; git clone -- https://github.com/google/subcommands /Users/user1/go/src/github.com/google/subcommands
Cloning into '/Users/user1/go/src/github.com/google/subcommands'...
fatal: unable to access 'https://github.com/google/subcommands/': Could not resolve host: github.com
package github.com/google/subcommands: exit status 128

When I open my web browser and go to: https://github.com/google/subcommands/ I can see the web page with no problems. So why is the "go get" command having trouble with this?

What am I doing wrong?

Solution

In addition of git config, you can also check your environment variable for HTTP_PROXY/HTTPS_PROXY

But more importantly, check if adding GOPROXY=https://proxy.golang.org could help (there are other Go module proxies as well)

This could help getting modules from any provider, GitHub or others.
