问题:

I tried pushing my app to heroku but get the following error:

remote: -----> Using Ruby version: ruby-2.2.2 remote: -----> Installing dependencies using 1.9.7 remote:        Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment remote:        Fetching gem metadata from https://rubygems.org/........... remote:        Fetching version metadata from https://rubygems.org/... remote:        Fetching dependency metadata from https://rubygems.org/.. remote:        Could not find net-ssh-2.10.0 in any of the sources remote:        Bundler Output: Fetching gem metadata from https://rubygems.org/........... remote:        Fetching version metadata from https://rubygems.org/... remote:        Fetching dependency metadata from https://rubygems.org/.. remote:        Could not find net-ssh-2.10.0 in any of the sources remote:  !     Failed to install gems via Bundler. remote:  !     Push rejected, failed to compile Ruby app

What can I do about this?

I've removed Gemfile.lock to see if rebuilding this file would make a difference, but it didn't. Also, I've tried gem uninstall net-ssh-2.10.0 and then bundle install before pushing to heroku. Also, I removed fog from my Gemfile since that's the gem with which net-ssh-2.10.0 comes along; then did bundle update, gem cleanup, put fog back in the Gemfile, ran bundle install, pushed to git, and pushed to heroku with again the same result.

My Gemfile:
