ruby-on-rails - 安装spree commerce时无法激活机架问题

Question

我使用 gem install spree 安装 spree 版本 0.9.4 并运行设置命令 spree mystore 并收到此错误消息。有没有人在 spree 中经历过这种情况？

D:\Workspaces>spree mystore
C:/Program Files/BitNami RubyStack/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:280:i
n `activate': can't activate rack (>= 1.0.1, runtime) for ["spree-0.9.4"], alrea

谢谢

Answer 1

我到处都发现了类似的问题(有不同的 gem)并决定通过安装一个新的 gem 并卸载旧的来解决它

gem uninstall rack -v 1.0.0

然后

gem install rack -v 1.0.1

希望对遇到类似问题的人有所帮助。
