Ruby on rails bundler无法在digital ocean上加载带有mina部署的命令unicorn

使用mina部署rails应用程序时显示此错误

bundler: failed to load command: unicorn (/home/kkteja/.rbenv/versions/2.2.3/bin/unicorn)
Gem::LoadError: unicorn is not part of the bundle. Add it to Gemfile.
  /home/kkteja/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/bundler-1.12.5/lib/bundler/rubygems_integration.rb:322:in `block in replace_gem'
  /home/kkteja/.rbenv/versions/2.2.3/bin/unicorn:22:in `<top (required)>'

认为gem锁文件有问题，所以我删除了它，运行了

bundle install

命令，然后进行mina部署。这是gem锁文件

几乎两天的研究，但仍然没有运气。一杯啤酒给帮助我处理这件事的极客

经过几天的挖掘，我终于发现问题出在代码被提交到回购协议上。Mina从repo获取代码的最新副本。我编辑了gem文件并向其中添加了unicorn，但是由于它没有提交，当mina获取代码库并安装它时，unicorn没有找到。希望这有帮助。

你能使用unicorn 4.9.0并尝试一下吗？尝试过@KumarAbinash，但输出相同。当我运行mina deploy时，我没有在

--->使用Bundler安装gem依赖项部分看到unicorn。你有多个分支吗？没有，我只有master branch。我建议你在deploy.rb文件中设置：branch，'master'，看看它是否有效。
