我想为我的购物车网站添加 Payupaisa 网关。我用狂欢。我用宝石
gem 'spree_payupaisa', :github => "meetdestiny/spree_payupaisa_express", :branch => "2-1-stable"
https://github.com/meetdestiny/spree_payupaisa_express
但是在我更新捆绑包时它会出错
Git error: command `git rev-parse 2-1-stable` in directory
/home/tps/.rvm/gems/ruby-2.0.0-p247@demo/cache/bundler/git/spree_payupaisa_express-6aebc199a8cbc824377ffe9416c892e73cc3271e has failed.
预先感谢。
