Question

我是 ROR 的新手，現在我正在安裝Spree ，以下步驟

gem install rails -v 3.1.4
rails new mystore
cd mystore
spree install

之后在這里顯示此錯誤

gemfile  spree
     gemfile  spree_usa_epay
     gemfile  spree_skrill
         run  bundle install from "."
Could not find gem 'spree_skrill (>= 0) ruby' in the gems available on this machine.

Run `bundle install` to install missing gems.

Answer 1

gem install spree_skrill

如果在那之后，您收到“在這台機器上可用的 gem 中找不到 gem 'spree_usa_epay (>= 0) ruby​​'”。

gem install spree_usa_epay

之后，我再次嘗試運行 >> spree install 並且它起作用了

Answer 2

就我而言，我收到此錯誤無法找到具有可執行文件狂歡 (Gem::GemNotFoundException) 的 gem 狂歡 (>= 0.a)

然后我運行這個命令：

gem install spree -v '>= 0.a'

有效...
