Answer 1

gem install spree_skrill

如果在那之后，你在这台机器上可用的宝石中找到“找不到宝石'spree_usa_epay（＆gt; = 0）ruby'。”

gem install spree_usa_epay

之后，我尝试运行＆gt;＆gt;狂欢安装再次，它工作

Answer 2

在我的例子中，我得到了这个错误can't find gem spree (>= 0.a) with executable spree (Gem::GemNotFoundException)

然后我运行这个命令：

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

它奏效了...
