Capistrano的安装在Ubuntu 14.04冲突

Question

我尝试设置capristrano部署 - 但有错误，

环境中的Ubuntu 14.04

红宝石： 红宝石-v 红宝石2.2.6p396（二○一六年十一月十五日修订56800 ）[x86_64-linux-gnu]

gem install capistrano 
Successfully installed capistrano-3.7.2

1 gem installed 



root@grek-Inspiron-11-3147:/tmp# gem install capifony 
Successfully installed capifony-2.8.6 
Parsing documentation for capifony-2.8.6

1 gem installed 

capifony . 
[skip] './Capfile' already exists 
[skip] './app/config/deploy.rb' already exists 
[done] symfony 2 project capifonied! 

我设置参数。

然后

cap deploy:setup 
(Backtrace restricted to imported tasks) 
cap aborted! 
Gem::ConflictError: Unable to activate capifony-2.8.6, because capistrano-3.7.2 conflicts with capistrano (<= 2.16.0, >= 2.13.5)

LoadError: cannot load such file -- capifony_symfony2

我如何解决这个错误？

Answer 1

错误消息解释该问题：

capistrano-3.7.2 conflicts with capistrano (<= 2.16.0, >= 2.13.5) 

换句话说，capifony显然需要Capistrano的< = 2.16.0，> = 2.13.5，但你已经安装了Capistrano的3.7.2。

解决方法是卸载capistrano并重新安装兼容版本。

gem uninstall capistrano 
gem install capistrano -v "<= 2.16.0, >= 2.13.5" 

你应该看到：

Fetching: capistrano-2.15.9.gem (100%)
