Ruby on rails Gemfile（Capistrano）中的语法错误

Capistrano给了我一个错误，说我把一个冒号放在了一个我甚至没有的宝石的错误位置。我应该如何解决这个问题？我猜只需指定

sdoc

就可以了，但我不确定正确的语法是什么<代码>gem'sdoc'，'~>0.4.0'失败

错误：（求和）

Gemfile

source 'https://rubygems.org'

加载项

Gemfile

group :doc do
  gem 'sdoc', require: false
end

---

然后，由于您的远程服务器正在运行Ruby<1.9，请将您的Gemfile更改为

gem 'sdoc', '~> 0.4.0', :group => :doc

---

但是，请立即切换到Ruby 2.2+主机—1.8.7不受支持，速度非常慢。

恐怕不行：/1仍然会出现同样的错误。我在日志中添加了完整的错误部分，以防遗漏任何重要信息。你真的在运行Ruby 1.9+？除非发生了某种奇怪的诡计，我相信我会的<代码>$ruby——版本ruby 2.2.2p95（2015-04-13修订版50295）[x86\u 64-linux]您能在服务器上确认吗？如果你做一个打印Ruby版本的Cap任务呢？@jmdeldin我是个白痴。出于某种原因，我认为只在本地检查是可以的。我的服务器是1.8.7，所以我有点搞砸了，因为它是共享主机

gem 'sdoc', '~> 0.4.0', :group => :doc
