cannot install with latest spree

[arthurtalkgoal]

failed to upgrade with latest spree version
spree_core (2.4.0.beta)

I found spree_alipay is on 2.2.0

spree_alipay only support spree 2.2 and 2.0 for now.
I'm really sorry but I don't have any bandwidth to help at the moment.
i wish i could upgrade it in next months.

I am trying to branch the spree 2-4-stable for alipay.

However, I found the spec failed.

Namely the link generated got ILLEGAL_PARTNER error.

Can I ask how can you get the API　partner, key and signature for alipay sandobx?
(I created a sandbox acct but seems not able to generate the API　key
https://sandbox.alipaydev.com)

@arthurtalkgoal , thanks for your work, first.
As far as i know, alipay sandbox do not support this feature. I was trying it. it does not work.
You have to prepare two alipay accounts, one is partner account( partner_id and key ). Create 1 cent product, try it manually.

I finally built a gem for latest spree, and spree_gateway.

Thanks for the info!
