框架是react, ?腳手架為dva官方腳手架下面是模塊共享數據文件 ==>modle/todos.jsconst?R?=?require('ramda')????//<===== //?import?R?from?'ramda'??????//<=====?? export?default?{ namespace:?'todos', state:?{ ????'list':?[ ????????{ ????????????'title':?'吃飯', ????????????'done':?true ????????}, ????????{ ????????????'title':?'睡覺', ????????????'done':?false ????????}, ????????{ ????????????'title':?'拉屎', ????????????'done':?false ????????} ????], ????'visible':?0, }, effects:?{ }, reducers:?{ ????change_todo(state,?action)?{ ????????return?R.set(R.lensProp('visible'),?action.visible,?state) ????}, }, };為什么將引包方式換成?import R from 'ramda'后會報錯,?報錯內容為TypeError: Cannot read property 'set' of undefined
