If scope is nil or 'public', skip email.

[igoodrich]

If the scope is nil or 'public', github denies access to the email and
omniauth raises a failure. This makes it so that if you want to use
github for read-only authentication, you can't (at least in an obvious
fashion).

There is a workaround: pass 'skip_info: true' on configuration. In this
case you do not get the 'nickname' and 'image', however.
For example, the following will work without this fix:
provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET'], skip_info:
true

The other solution, without this patch, is to specify at least the user
scope, like so:
provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET'], scope:
'user'

Hi, I tried to make this fit into the existing code as best I could. I hope it's okay. Please let me know if you have any questions about the issue. --Ian

we are also facing this issue, using the gem through your git repo works, but would love to see this pull request merged

[prashantrajan]

Facing this same issue. Hoping this gets merged into master

[cjamison]

Ran into this issue as well.

as a temp workaround, I'm using in my Gemfile:

gem 'crowdint_omniauth-github', :require => 'omniauth-github'

Ran into the same problem. Hopefully this will get looked at soon; without it, this strategy is broken when the app uses public scope and the user has no public email address.

I've just faced the same problem. Why this PR isn't merged?

@mbleigh just pinging you on this real quick. Looks like quite a few people are hitting this problem.
