使用Rubber降低rails gem

Question

我有一个rails gem，由于新版本存在问题，我需要降级到旧版本：aws-sdk

我已经更新了我的本地Gemfile并推送到我的git服务器：

gem 'aws-sdk', '< 2.0'

现在，我需要使用降级的gem更新我的生产服务器，而不是它当前拥有的更新版本。

我尝试cap deploy，但收到此错误：

 ** [out :: app01-myserver.com] You are trying to install in deployment mode after changing
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] your Gemfile. Run `bundle install` elsewhere and add the
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] updated Gemfile.lock to version control.
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] You have added to the Gemfile:
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] * aws-sdk (< 2.0)
 ** [out :: app01-myserver.com] 
 ** [out :: app01-myserver.com] You have deleted from the Gemfile:
 ** [out :: app01-myserver.com] * aws-sdk

那么，是否可以从命令行运行cap或rubber命令来更新Gemfile？

Answer 1

如错误消息中所述，您应该将InputField添加到git。在它运行Gemfile.lock之后，提交bundle update aws-sdk中的更改，推送它并使用Gemfile.lock部署到生产服务器。
