Rails 3.2.2 在我的开发环境和服务器上都运行良好。
我正在尝试通过更改升级到 3.2.3:
gem 'rails', '3.2.2'
到
gem 'rails', '3.2.3'
然后运行:
bundle update
bundle
一切顺利,直到我尝试部署到我的服务器。在部署期间,我收到以下消息:
An error occured while installing railties (3.2.3), and Bundler cannot continue.
Make sure that `gem install railties -v '3.2.3'` succeeds before bundling.
我已登录服务器并运行 gem install railties -v '3.2.3' 命令,它可以正常工作。但是部署总是以同样的方式失败。
我已尝试删除此处显示的缓存目录,但我不确定我是否正确执行此操作。我在服务器和我的开发环境上使用 rvm。
任何人都可以帮我指出这个方向吗?
这是我的 deploy.rb 文件:
require "bundler/capistrano"
$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.
require "rvm/capistrano" # Load RVM's capistrano plugin.

更新
我最终能够通过部署到不同的用户来解决这个问题。但问题仍然存在:如何为老用户清除 gem 缓存?
