致命错误：消息为“ environment”的未捕获异常“ Braintree_Exception_Configuration”需要设置。

Question

How to set the environment? And how to rectify this error?

Fatal error: Uncaught exception 'Braintree_Exception_Configuration'

Answer 1

Message is pretty selfexplanatory. You need to call

Braintree_Configuration::environment(...);

with proper parameter prior using BT, as it needs to know if you want to talk to production or sandbox.
