__WEBPACK_IMPORTED_MODULE_3_vuex__.a is not a constructor

 

错误代码

 

let store = new Vuex({
  state: {
    totalPrice: 0
  },
  mutations: {
    increment (state, price) {
      state.totalPrice += price
    },
    decrement (state, price) {
      state.totalPrice -= price
    }
  }
})

 

正确代码：

let store = new Vuex.Store({
  state: {
    totalPrice: 0
  },
  mutations: {
    increment (state, price) {
      state.totalPrice += price
    },
    decrement (state, price) {
      state.totalPrice -= price
    }
  }
})

　

　

分析：构造器写法写错了应该是new Vuex.Store({})

 

下面请忽略。。

 

　

let store = new Vuex({
state: {
totalPrice: 0
},
mutations: {
increment (state, price) {
state.totalPrice += price
},
decrement (state, price) {
state.totalPrice -= price
}
}
})
