我尝试设置capristrano部署 - 但有错误，
环境是Ubuntu 14.04
红宝石： 红宝石-v ruby 2.2.6p396（2016-11-15修订版56800）[x86_64-linux-gnu]gem install capistrano

然后

我如何解决这个错误？
答案 0 :(得分：2)
错误消息解释了问题：
capistrano-3.7.2 conflicts with capistrano (<= 2.16.0, >= 2.13.5)
换句话说，capifony显然需要capistrano＆lt; = 2.16.0，＆gt; = 2.13.5，但你已经安装了capistrano 3.7.2。
解决方案是卸载capistrano并重新安装兼容版本。
gem uninstall capistrano
gem install capistrano -v "<= 2.16.0, >= 2.13.5"
您应该看到：
Fetching: capistrano-2.15.9.gem (100%)
Successfully installed capistrano-2.15.9
