I have the following line in my gemfile:
gem 'client_side_validations', :git => "[email protected]:Dakuan/client_side_validations.git", :branch => "master", ref: '2245b4174ffd4b400d999cb5a2b6dccc0289eb67'
The repo it’s pointing at is public and I can run bundle install / update locally just fine. When I try to push to Heroku I get the following error:
Fetching [email protected]:Dakuan/client_side_validations.git Host key verification failed. fatal: The remote end hung up unexpectedly Git error: command `git clone '[email protected]:Dakuan/client_side_validations.git' "/tmp/build_1xa9f06n4k1cu/vendor/bundle/ruby/1.9.1/cache/bundler/git/client_side_validations-56a04875baabb67b5f8c192c6c6743df476fd90f" --bare --no-hardlinks` in directory /tmp/build_1xa9f06n4k1cu has failed.
! Failed to install gems via Bundler.
! Heroku push rejected, failed to compile Ruby/rails app
Anyone got any ideas about what’s going on here?
Use this GitHub URL instead:
[email protected]:… URL is the writable SSH version, which requires authentication with an SSH key connected to a GitHub account that has write access to the repository.
git://github.com/… URL is the public, read-only version.
Since the gem you’re using is in a public GitHub repository, you can also use this shorthand in your Gemfile:
gem 'client_side_validations', :github => 'Dakuan/client_side_validations'
See the Bundler Git documentation for more information.
A late second answer, as I ran into some confusing output from Heroku’s build logs which stumped me for a while.
If you have multiple Github hosted gems in your Gemfile, and one of them is inaccessible (in my case, I had accidentally pointed to a private repo of mine), the build logs throw an error like
Username not found or
Repository not found for all the Github hosted gems – even those that are available.
