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
Successfully installed capistrano-3.7.2

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

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

我设置了参数。

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)

我如何解决这个错误？

【解决方案1】：

错误信息说明了问题：

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

换句话说，capifony 显然需要 capistrano = 2.13.5，但你已经安装了 capistrano 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%)
Successfully installed capistrano-2.15.9
1 gem installed
