go get results in 'terminal prompts disabled' error for GitHub private repo

I created the private repo examplesite/myprivaterepo using the GitHub UI from my browser.

Then I went to my go directory (on the desktop) and cloned it:

$ cd $GOPATH
$ go get github.com/examplesite/myprivaterepo

So far so good. Created the file scheduler.go, added to repo and pushed.

$ vim scheduler.go
$ git add scheduler.go
$ git commit
$ git push

Everythng's OK. But when I went to a clean laptop and tried to clone the repo, I got an error:

# Now on laptop, which doesn't yet know about the repo
$ cd $GOPATH
$ go get github.com/examplesite/myprivaterepo
# At this point it should ask for my user ID and password ,right? But it doesn't.
# Instead, this error occurs:
cd .; git clone https://github.com/examplesite/myprivaterepo /Users/tom/go/src/github.com/examplesite/myprivaterepo
Cloning into '/Users/tom/go/src/github.com/examplesite/myprivaterepo'...
fatal: could not read Username for 'https://github.com': terminal prompts disabled
package github.com/examplesite/myprivaterepo: exit status 128

Why is my laptop hating on my own repo and how can I get it to accept its fate?

Thanks.

Solution

It complains because it needs to use ssh instead of https but your git is still configured with https. so basically as others mentioned previously you need to either enable prompts or to configure git to use ssh instead of https. a simple way to do this by running the following:

git config --global --add url."git@github.com:".insteadOf "https://github.com/"

or if you already use ssh with git in your machine, you can safely edit ~/.gitconfig and add the following line at the very bottom

Note: This covers all SVC, source version control, that depends on what you exactly use, github, gitlab, bitbucket)

# Enforce SSH
[url "ssh://git@github.com/"]
  insteadOf = https://github.com/
[url "ssh://git@gitlab.com/"]
        insteadOf = https://gitlab.com/
[url "ssh://git@bitbucket.org/"]
  insteadOf = https://bitbucket.org/

If you want to keep password pompts disabled, you need to cache password. For more information on how to cache your github password on mac, windows or linux, please visit this page.

Also, more importantly, if this is a private repository for a company or for your self, you may need to skip using proxy or checksum database for such repos to avoid exposing them publicly.

To do this, you need to set GOPRIVATE environment variable that controls which modules the go command considers to be private (not available publicly) and should therefore NOT use the proxy or checksum database.

The variable is a comma-separated list of patterns (same syntax of Go's path.Match) of module path prefixes. For example,

export GOPRIVATE=*.corp.example.com,github.com/mycompany/*

go env -w GOPRIVATE=github.com/mycompany/*

For more information on how to solve private packages/modules checksum validation issues, please read this article.

One last thing not to forget to mention, you can still configure go get to authenticate and fetch over https, all you need to do is to add the following line to $HOME/.netrc

machine github.com login USERNAME password APIKEY

For GitHub accounts, the password can be a personal access tokens.
