由于 gem 捆绑程序，应用程序无法推送到 heroku（无法将主机添加到已知主机列表 (/home/group_home/.ssh/known_hosts)）

Question

当我尝试推动狂欢沙盒车来测试我要使用的扩展时，我遇到了这个错误。

我的 Gemfile

gem 'spree_flexi_variants', :git=>'[email protected]:jsqu99/spree_flexi_variants.git', :branch => 'pre-deface-stable'

Heroku Push 的输出：

julio@ubuntu:~/rails/sandboxcart $ git push heroku master

应用程序正确运行并使用 gem，但在尝试部署时会发生该错误。我仍在排除故障的过程中，但任何帮助将不胜感激。

Answer 1

进行以下更改：

gem 'spree_flexi_variants', :git=>'[email protected]:jsqu99/spree_flexi_variants.git', :branch => 'pre-deface-stable'

TO

gem 'spree_flexi_variants', :git=>"git://github.com/jsqu99/spree_flexi_variants.git", :branch => 'pre-deface-stable'

应该可以，并且与您的 heroku 密钥无关。

Answer 2

这看起来像是您的 SSH 密钥的问题。

Heroku 站点 提供了有关如何管理 SSH 密钥的说明。

尝试 heroku keys 并确保您已正确配置。
